For this reason, the sections concerning each works formal aspects will be deemphasized.
There are two terms you will need to understand in depth for this next section, nativity and annunciation.
According to the Brittanica,
a nativity is a theme in Christian art depicting the newborn Jesus with the Virgin Mary and other figures, following descriptions of Christ's birth in the Gospels and Apocrypha. An old and popular subject with a complicated iconography, the Nativity was first represented in the 4th century, carved on Early Christian Roman sarcophagi, and was later included with other scenes from Christ's life in monumental decoration of Early Christian basilicas. It was a very important subject for Early Christian art from the 5th century because it emphasized the reality of the incarnation of Christ and the validity of the Virgin's newly established (431) title of Theotokos (Mother of God). The Early Christian version of the Nativity shows the Virgin seated, to emphasize that the birth was painless, and the Child, in swaddling clothes, lying in a manger. The two, along with an ox and an ass, are under the roof of a barnlike stable. Usually one or two shepherds, who symbolize the revelation of Christ to the Jews, and often also the Magi--Wise Men from the East who symbolize his revelation to the Gentiles--appear in the scene. By the 6th century another version of the Nativity appeared in Syria, becoming universal in the East throughout the Middle Ages, and in Italy until the late 14th century. It differs from the earlier version, which was retained with some modifications in northwestern Europe, mainly in that it shows the Virgin lying on a mattress, thus ignoring the concept of the painless birth. The Child is again in swaddling clothes in a manger, and the ox and ass are retained, but the stable is located not in a barn but in a cave, as was the custom in Palestine. Angels usually hover above the cave, and Joseph sits outside it. The Magi and the shepherds are often present. The announcement of the miraculous birth to the shepherds by an angel and the journey of the Magi may be depicted simultaneously in the background. Another simultaneous representation--the bathing of the Child by two midwives in the foreground--became standard in Eastern Nativities. It probably derives from classical scenes of the birth of the god Dionysus and is a prefiguration of Christ's Baptism. As the emblem of a major feast day, this version of the Nativity figured prominently, usually in its most complicated form, in the liturgical iconography of Byzantine church decoration.
In the late 14th century an abrupt transformation of the iconography of the Nativity occurred throughout western Europe, including Italy, and a second major version came into being. This was essentially an adoration; the most important change is that the Virgin is depicted no longer in the aftermath of childbirth but kneeling before the Child, who is now nude and luminous and lies not in a manger but on the ground on a pile of straw or a fold of the Virgin's mantle. Often Joseph, too, kneels in adoration. Most of the other details, except the ox and ass, are omitted, especially in earlier works. This version, which seems to have spread from Italy, follows in detail--and in fact almost certainly originates with--an account of a vision by St. Bridget of Sweden, an influential 14th-century mystic. Universally adopted in western Europe by the 15th century, this version is widely depicted in altarpieces and other devotional works.
In the Renaissance, angels reappeared, and the scene was often combined with the adoration of the shepherds, which had recently developed as a separate theme. The midwives were still included occasionally. In the 16th century the Council of Trent outlawed the midwives, the ox and ass, and the bathing of Christ as ignoble, apocryphal, and theologically unsound (the bathing of the Child is inconsistent with the doctrine of a pure and supernatural birth).
In the 17th century a more prosaic representation reappeared, with the Virgin again reclining and holding the Child. After the 17th century, despite the decline of Christian religious art in general, the Nativity remained an important theme in the popular arts.

According to the Brittanica,
the Annunciation in Christianity, the announcement by the angel Gabriel to the Virgin Mary that she would conceive a Son of the Holy Spirit to be called Jesus (Luke 1:26-38). The Feast of the Annunciation, one of the principal feasts of the Christian church, is celebrated on March 25 (Lady Day). The first authentic allusions to the feast (apart from the Gelasian and Gregorian sacramentaries, in both of which it is mentioned) are in acts of the Council of Toledo (656) and of the Trullan Council (692).
Because its significance is much more than narrative, the Annunciation had a particularly important place in the arts and church decoration of the early Christian and medieval periods and in the devotional art of the Renaissance and Baroque. Moreover, because, in Christian doctrine, the event coincides with the Incarnation of Christ, it also represents a prelude to the redemption of the world.

Nicola Pisano. Nativity, 
detail of Baptistery Pulpit panel: Annunciation, 
Nativity and Annunciation to Shepherds 1259-60
Italian Gothic,
Form:  This is a relief carving.  The relief varies greatly in the height and or depth of each of the figures and objects.  In general the composition is fairly symmetrical yet it is very crowded and almost seems disorganized.  Most of the figures are placed in the foreground of the picture plane and the space created is not very illusionistic.  Space is created by placing the figures in the foreground lower in the picture plane.  In order to show the recession of space, the figures are layered and the placed in a vertical perspective.  The rendering of each of the figures is fairly naturalistic and the clothing, drapery and poses are somewhat reminiscent of carvings such as the this one from the Parthenon's pediment.  Several of the figures, such as the main one which depicts Mary and the child (Jesus) are repeated because several scenes are simultaneously being represented.  This kind of continuous narrative is common in Byzantine, Romanesque, Gothic and Renaissance art. 
Iconography:  This is a nativity scene that at first appears to take place in a manger but it also contains the baptism of Christ as well as the annunciation by the angel Gabriel.  The scenes are as follows, far left the angel Gabriel confronts Mary with his annunciation of the birth of Jesus. Mary pulls away towards the center of the scene.  In the upper right hand corner is a manger scene in which Jesus lies in his crib, at the far right are two of the wise men who are missing their heads.  The center of the scene Mary reclines in a pose very reminiscent of the Goddesses from Parthenon.  In the lower left foreground of the image is the baptism of Christ (note he's missing his head too.)

Duccio di Buoninsegna, The Nativity with the Prophets Isaiah and Ezekiel, 1308/1311
This panel in the National Gallery, Washington DC
Form: The rendering of each of the figures is fairly naturalistic and the clothing, drapery and poses are somewhat reminiscent of Nicola Pisano's Nativity, from the Baptistery Pulpit panel and carvings such from the Parthenon's pediment.  Several of the figures, such as the main one which depicts Mary and the child (Jesus) are repeated because several scenes are simultaneously being represented.  This kind of continuous narrative is common in Byzantine, Romanesque, Gothic and Renaissance art.  Iconography:  This is a nativity scene that at first appears to take place in a manger but it also contains the baptism of Christ as well.  The center of the scene Mary reclines in a pose very reminiscent of the Goddesses from Parthenon.  In the lower left foreground of the image is the baptism of Christ.
 
 
The figures that flank the main scene serve as a kind of framing device that also update the image and provide transitional figures that bridge the gap between Mary, Jesus and us.  The image of the saint in Catholic art and religious practice is one that symbolizes our possibilities.  The saints were normal people, who in their emulation of Christlike qualities show us what every person is capable of attaining.  When Catholics pray to them they are asking for the saint to intercede with God.  Basically ask God for a favor for us. Context:  It is easy to guess that Duccio probably used, almost directly Nicola Pisano's Nativity, from the Baptistery Pulpit panel as his schema.  This was not considered plagiarism by the Gothic artists but rather a compliment and a continuation of a time honored Byzantine tradition.  Her pose and drapery almost exactly mimic Nicola Pisano's Nativity, from the Baptistery Pulpit panel but the drapery is somewhat less lifelike.  This also demonstrates the desire to continue older visual traditions and to not always have a revolutionary and innovative stylistic break with earlier traditions.
 

Duccio di Buoninsegna, Annunciation 1308-11
Tempera on wood, 43 x 44 cm 
National Gallery, London
predella Maesta Altar
Form: Duccio's Annunciation scene shares some of the same formal devices that the other works we've looked at.  There is no deep space but there is an attempt to relate the figures to the architectural environment they reside in.  There is a consistent sense of chiaroscuro that unifies the picture plane.  The drapery of the figures is beginning to demonstrate a shift of light and shadow (chiaroscuro) that we see in Giotto's work and the drapery begins to actually feel as if the anatomy beneath is revealed in how the drapery hangs on the figures.  The composition is still symmetrical but there is an out door in door feeling to the image.  Mary is framed within an arch like structure. Iconography:  The increased illusionism of the image is symbolic of some of the growing humanistic trends in the Catholic faith that is further evidenced by the philosophies of St. Francis.
Both Mary and Gabriel are dressed in a cross between Byzantine clothing and Roman style togas indicating a  historicism about them.  The colors used for the clothing are expensive and so is the gold leaf in  the background.  Both the figures heads are adorned with halos that are ornamneted with punchwork.
Mary is holding either a book of hours or a Bible.  Brittanica describes a book of hours as a,
devotional book widely popular in the later Middle Ages. The book of hours began to appear in the 13th century, containing prayers to be said at the canonical hours in honour of the Virgin Mary. The growing demand for smaller such books for family and individual use created a prayerbook style enormously popular among the wealthy. The demand for the books was crucial to the development of Gothic illumination. These lavishly decorated texts, of small dimensions, varied in content according to their patrons' desires.
She pulls away slightly from Gabriel as he announces that she will be having the son of god demonstrating a very human response and therefore humanistic perspective.  Above her head flying in through the combination Gothic/Triumphal arch is the holy spirit which is represented as a dove.  This is also a reference to the story of Noah as a typology.  The architectural structure is designed to look like both a Church and a triumphal arch.  This is representative of Mary's house as the house of God and a place of worship.  The scepter Gabriel holds represents triumph. Between the two figures is a vessel filled with lilies.  The vessel refers to Mary's role as the "vessel of God" and the white flowers refer to her purity.  In fact there is a whole iconographic system devoted to flowers and Mary.


Simone Martini, Annunciation, 1333 10'x8' 
(central panel)  Lippo Memmi, (Wings)
Frame 19th C Anonymous
Florence Uffizi
Italian Late Gothic/Early Renaissance
Form: Martini's Annunciation scene shares some of the same formal devices that the other works we've looked at too.  There is no deep space whatsoever in this image because of the use of gold leaf for the background.  The drapery of the figures is beginning to demonstrate chiaroscuro and anatomical structure but in some ways less so then some of the other images.  The composition is perfectly symmetrical and the figures are placed beneath each of the three pointed Gothic style arches. Iconography:  As in the other works the  increased illusionism of the image is symbolic of some of the growing humanistic trends in the Catholic faith that is further evidenced by the philosophies of St. Francis.
Both Mary and Gabriel are dressed in a cross between Byzantine clothing and Roman style togas indicating a  historicism about them.  The colors used for the clothing are expensive and so is the gold leaf in  the background.  Both the figures heads are adorned with halos that are ornamneted with punchwork.  However, there is a bit more in terms of their ornamnetation.  The checked pattern on Gabriel's gown may actually be a reference to either a popular style of fabric design or a type of fabric produced by the patron.  In this way it is a form of "product placement."  Mary is holding a book of hours and like Duccio's painting she pulls away slightly from Gabriel as he makes his announcement. 
A possible reference to the literacy of the wealthy may be the words inscribed in the gold leaf which emenate from Gabriel's mouth, "Hail favored one!  The Lord is with you."
Plant forms figure powerfully into this kind of image.  Between the two figures is a vessel filled with lilies.  The vessel refers to Mary's role as the "vessel of God" and the white flowers refer to her purity.  In fact there is a whole iconographic system devoted to flowers and Mary.  The olive branch is a reference to the story of Noah in which the dove brings an olive branch back to the ark and this is a symbol of God's renewed covenant with Noah.  The wreath of olives around Gabriel's head is a similar refernce both also refers to the Greek and Roman traditions of honoring heroes and athletes with the laurel wreaths on there head as an impromptu crown.  It may also be a reference to Christ's crwon of thorns. The central panel of the altar is in a tripartite division (three part).  This is possibly a reference to the holy trinity which is "in Christian doctrine, the unity of Father, Son, and Holy Spirit as three persons in one Godhead," according to the Brittanica.  It also designed to look like the arches in a Gothic church.  In the central bay of the image is an image of the holy spirit surrounded by a series of cherubim in the form of sparrows.  The sparrow comes up quite a bit as a symbol of the word of God and as cherubim.

  • Form:  Before you read this section, read in Stokstad the section called, Technique, Cennini on Panel Painting. Form:  The overall composition of this work is symmetrical.  The largest figures of Mary and Jesus are at the center of the composition and they are flanked by two rows of angels and Saints overlapped as if they are standing on bleachers.  In order to create space, Duccio uses the same convention of vertical perspective we saw in Pisano's pulpit.  The figures that are highest up in the picture plane are furthest back.
    This painting was rendered with tempera paint and gold leaf.  Tempera is a medium which is made from egg (sometimes just the yolk sometimes the whites) glue and ground up minerals that serve as pigment or colorant.  The egg actually glues or binds the pigments to the surface.  The paint is applied in small distinct brush strokes that show the brushwork when looked at closely. 
    The background is gold leaf on a wooden panel that has been painted with a a combination of glue and marble dust or chalk referred to as gesso.  The gold leaf is then incised and punctured with designs (Stokstad calls this punchwork.)  Gold leaf has also been added to the drapery as a means to highlight the folds. 
    The rendering of color and value in this painting is fairly limited.  There is no distinct source of light and very little tonal variation on the faces or drapery of the individual figures and there are no real differences of character or appearance from one face to the next.
    Duccio's rendition of the Virgin is very similar to the one from Auvergne and Cimabue's.  This painting, like the sculpture, is both naturalistic and stylized.  Again the rendering of the face and hands was an attempt by the sculptor to represent convincing human forms however, the faces show no real expression and the bodies are completely covered with an almost Byzantine style of drapery that almost completely conceals both figures' bodies.  The child Jesus is not rendered as a child buy rather a stiff looking miniature adult.  The poses of both figures are stiff and fairly wooden but in the case of Mary, this is appropriate if you look at her role in  terms of the work's iconography.
    Iconography:  As in the French Gothic sculpture Mary is depicted as the "Throne of Wisdom."   The arrangement of the composition places Mary at the center of the image and in the most important location.  So the use of symmetry and the placement of figures can indicate their status.  Notice that Mary is framed and as such "backed up" by the angels.  The less important figures of the prophets are literally beneath her and Jesus. Color and the gold leaf used also serve as iconographic reminders of Mary and Jesus' status.  Gold leaf and red and blue pigments were made from precious stones and materials and are symbols of there status.
    Context: According to the Brittanica,
    Maestà (Italian: "Majesty"), double-sided altarpieces executed for the cathedral of Siena by the Italian painter Duccio. The first version (1302), originally in the Palazzo Pubblico in Siena, is now lost. The second version (Oct. 9, 1308-June 9, 1311), painted for the cathedral of Siena and one of the largest altarpieces of its time, consisted of a wide frontal panel with the Virgin and Child adored by the patrons of Siena and surrounded by saints and angels. Beneath was a predella with seven scenes from the childhood of Christ; above were pinnacles with scenes from the life of the Virgin; and on the back were scenes from the life of Christ. The main panel and the bulk of the narrative scenes are now in the Museo dell'Opera Metropolitana, Piazza del Duomo, Siena, but isolated panels from the altarpiece have found their way to the National Gallery, London; the Frick Collection, New York City; and the National Gallery of Art, Washington, D.C.
    The work in which the genius of Duccio unfolds in all its brilliant fullness and the one to which the painter owes his greatest fame, however, is the "Maestà," the altarpiece for the main altar of the cathedral of Siena. He was commissioned to do this work on Oct. 9, 1308, for a payment of 3,000 gold florins, the highest figure paid to an artist up to that time. On June 9, 1311, the whole populace of Siena, headed by the clergy and civil administration of the city, gathered at the artist's workshop to receive the finished masterpiece. They carried it in solemn procession to the accompaniment of drums and trumpets to the cathedral. For three days alms were distributed to the poor, and great feasts were held. Never before had the birth of a work of art been greeted with such public jubilation and never before had there been such immediate awareness that a work was truly a masterpiece and not just a reflection of the religious fervor of the people. Duccio himself was aware of the work's significance; he signed the throne of the Virgin with an invocation that was devout yet proud for the time: "Holy Mother of God, grant peace to Siena, and life to Duccio because he has painted you thus." The "Maestà" is in the form of a large horizontal rectangle, surmounted by pinnacles, and with a narrow horizontal panel, or predella, as its base. It is painted on both sides. The entire central rectangle of the front side is a single scene showing the Madonna and Child enthroned in the middle of a heavenly court of saints and angels with the four patron saints of Siena kneeling at their feet. The back is subdivided into 26 compartments that illustrate the Passion of Christ. The front and back of the predella contain scenes of the infancy and the ministry of Jesus, and the pinnacles, crowning the entire work, represent events after the Resurrection. In all, there are 59 narrative scenes.
    The rigorous symmetry with which the groups of adoring figures at the sides of the Virgin are arranged in the imposing scene of the central panel is inspired by compositions of the Byzantine tradition and gives evidence of Duccio's keen architectural sensibility by its power to draw attention to the "Maestà" as the true focal point of the cathedral's spatial and structural organization. Like elements of a living architecture, the 30 figures, through the slightest of gestures and turnings of the head, are intimately related, their positions repeated to give a feeling of intense lyrical contemplation. The consonance of feeling that arises from this contemplation gives the facial features of each a distinct, spiritual beauty, reminiscent, especially the faces of the angels, of the more idealistic creations of Hellenistic art. The Madonna, slightly larger than the other figures, seated on a magnificent and massive throne of polychrome marbles, inclines her head gently as if trying to hear the prayer of the faithful. Duccio thus succeeds in reconciling perfectly the Byzantine ideal of power and dignity with the underlying tenderness and mysticism of the Sienese spirit. The scenes in the predella, pinnacles, and back are filled with the Byzantine iconographic schemes from which Duccio finds it difficult to detach himself, and they are developed with a deeper concern for their narrative significance. The scenes are not, however, merely descriptions or chronicles. They include many touches from daily life, which provide a lyrical synthesis that harmonizes the character and gestures of the figures with their landscape and architectural surroundings.
    Briitanica Encyclopedia
    At this time the altarpiece for the high altar was finished and the picture which was called the "Madonna with the large eyes" or Our Lady of Grace, that now hangs over the altar of St. Boniface, was taken down. Now this Our Lady was she who had hearkened to the people of Siena when the Florentines were routed at Monte Aperto, and her place was changed because the new one was made, which is far more beautiful and devout and larger, and is painted on the back with the stories of the Old and New Testaments. And on the day that it was carried to the Duomo the shops were shut, and the bishop conducted a great and devout company of priests and friars in solemn procession, accompanied by the nine signiors, and all the officers of the commune, and all the people, and one after another the worthiest with lighted candles in their hands took places near the picture, and behind came the women and children with great devotion. And they accompanied the said picture up to the Duomo, making the procession around the Campo, as is the custom, all the bells ringing joyously, out of reverence for so noble a picture as this. And this picture Duccio di Niccolò the painter made, and it was made in the house of the Muciatti outside the gate a Stalloreggi . And all that day persons, praying God and His Mother, who is our advocate, to defend us by their infinite mercy from every adversity and all evil, and keep us from the hands of traitors and of the enemies of Siena. This account reminds us how we should remember the integral role of a major work like this in the civic life of the city. Notice also how the adoration devoted to this new image is comparable to that shown the relics of a patron saint of a community. It is important to remember that the Virgin was the patron saint of Siena, and as such she was the center of the civic and religious life of the city. Kneeling beside the throne of the Virgin are the other patron saints of Siena: Ansanus, Sabinus, Crescentius, and Victor. The order of the altarpiece and the privileged position given to the Sienese saints, especially the Virgin, would have been clearly understood to reflect the ideal order of the city of Siena which would stand before it in the Duomo. The civic implications are further brought out by the original inscription: HOLY MOTHER OF GOD BESTOW PEACE ON SIENA AND SALVATION ON DUCCIO WHO PAINTED THEE.
    The reference in the account above to the Madonna with the Large Eyes , or in Italian --Madonna degli Occhi Grossi-- relates to a painting done about 1200:
    This work was seen to be a miracle working image. The Sienese appeals to this image of their patron saint were believed to have lead to the salvation of the city from the Florentines in the Battle of Montaperti in 1260. Why do you think the Sienese would have wanted to have replaced such a revered image with the Duccio altarpiece?

    Duccio di Buoninsegna
    The Nativity with the Prophets Isaiah and Ezekiel, 1308/1311
    This panel in the National Gallery, Washington DC
    Form: In general the composition is fairly symmetrical yet it is very crowded and almost seems disorganized.  Most of the figures are placed in the foreground of the picture plane and the space created is not very illusionistic.  Space is created by placing the figures in the foreground lower in the picture plane.  In order to show the recession of space, the figures are layered and the placed in a vertical perspective.  The rendering of each of the figures is fairly naturalistic and the clothing, drapery and poses are somewhat reminiscent of Nicola Pisano's Nativity, from the Baptistery Pulpit panel and carvings such from the Parthenon's pediment.  Several of the figures, such as the main one which depicts Mary and the child (Jesus) are repeated because several scenes are simultaneously being represented.  This kind of continuous narrative is common in Byzantine, Romanesque, Gothic and Renaissance art. 
    Iconography:  This is a nativity scene that at first appears to take place in a manger but it also contains the baptism of Christ as well.  The center of the scene Mary reclines in a pose very reminiscent of the Goddesses from Parthenon.  In the lower left foreground of the image is the baptism of Christ. The next major difference is in the style and amount of artwork. In general, the Gothic style is extremely organized, diagrammatic, and stylized. It tends to take cues from Byzantine and Romanesque art, in which the figures' relative size to another figure is based upon its' importance in the spiritual hierarchy. For example, when Jesus or an Angel is shown, they are relatively larger than all the other figures whom are depicted in a particular scene. This shows how important they are, they loom above the mere mortals, faithful and sinners alike.
    Context:  It is easy to guess that Duccio probably used, almost directly Nicola Pisano's Nativity, from the Baptistery Pulpit panel as his schema.  This was not considered plagiarism by the Gothic artists but rather a compliment and a continuation of a time honored Byzantine tradition.  Her pose and drapery almost exactly mimic Nicola Pisano's Nativity, from the Baptistery Pulpit panel but the drapery is somewhat less lifelike.  This also demonstrates the desire to continue older visual traditions and to not always have a revolutionary and innovative stylistic break with earlier traditions.

    Duccio di Buoninsegna, (Maestà)
    detail Christ Entering Jerusalem
    (Maestà, reverse of the top panel called "verso")
    1308-11Tempera on wood
    Museo dell'Opera del Duomo, Siena
    Form:  Probably the most significant stylistic and formal element of note is the awkward construction of space.  Here, Duccio attempts to create some sort of space but is a bit confused as to how to do it.  He uses vertical perspective to create space initially.  He places the figures that are closest to the viewer the lowest in the picture plane and those further back higher up.  The use of vertical perspective seems to tip the ground plane up and places the viewer in a helicopter or tower in which they are about 15 feet off the ground looking down on the scene. He also uses overlapping and a size scale difference between foreground and background.  Some of the figures in the crowd overlap and hide the figure's behind them but this really doesn't happen with the figures of the apostles, probably because he wanted to make sure the viewer was able to see all their faces.  The figures in the background are significantly smaller but the scale of the building and the way in which the apostles who follow Jesus are bunched up is a bit illogical.  There is not enough space on the ground for all the apostles nor the crowds to be standing together. 
    Context:  In order to understand the iconography of this scene one needs to go to the Bible passage on which it is modeled first:
    Matthew Chapter 21
    1
    When they drew near Jerusalem and came to Bethphage on the Mount of Olives, Jesus sent two disciples,
    2
    saying to them, "Go into the village opposite you, and immediately you will find an ass tethered, and a colt with her. Untie them and bring them here to me.
    3
    And if anyone should say anything to you, reply, 'The master has need of them.' Then he will send them at once."
    4
    This happened so that what had been spoken through the prophet might be fulfilled:
    5
    "Say to daughter Zion, 'Behold, your king comes to you, meek and riding on an ass, and on a colt, the foal of a beast of burden.'"
    6
    The disciples went and did as Jesus had ordered them.
    7
    They brought the ass and the colt and laid their cloaks over them, and he sat upon them.
    8
    The very large crowd spread their cloaks on the road, while others cut branches from the trees and strewed them on the road.
    9
    The crowds preceding him and those following kept crying out and saying: "Hosanna to the Son of David; blessed is he who comes in the name of the Lord; hosanna in the highest."
    10
    And when he entered Jerusalem the whole city was shaken and asked, "Who is this?"
    11     And the crowds replied, "This is Jesus the prophet, from Nazareth in Galilee."
    Iconography:  Most of the iconography is fairly standard in this image.  Jesus is depicted in he usual manner, he has a beard and is depicted, as his apostles with a beautiful nimbus of gold around his head.  His halo is literally the light of divine knowledge which radiates from him.  The royal red and blue colors he wears and the gold leaf are all meant to emphasize his status, however, he is also humble.  He rides a common beast of burden to show his connection to all men.

    Duccio paints with tempera paint.  According to the Brittanica.
     
    Tempera
    A tempera medium is dry pigment tempered with an emulsion and thinned with water. It is a very ancient medium, having been in constant use in most world cultures, until in Europe it was gradually superseded, during the Renaissance, by oil paints. Tempera was the original mural medium in the ancient dynasties of Egypt, Babylonia, Mycenean Greece, and China and was used to decorate the early Christian catacombs. It was employed on a variety of supports, from the stone stelae (or commemorative pillars), mummy cases, and papyrus rolls of ancient Egypt to the wood panels of Byzantine icons and altarpieces and the vellum leaves of medieval illuminated manuscripts. True tempera is made by mixture with the yolk of fresh eggs, although manuscript illuminators often used egg white and some easel painters added the whole egg. Other emulsions have been used, such as casein glue with linseed oil, egg yolk with gum and linseed oil, and egg white with linseed or poppy oil. Individual painters have experimented with other recipes, but few of these have proved successful; all but William Blake's later tempera paintings on copper sheets, for instance, have darkened and decayed, and it is thought that he mixed his pigment with carpenter's glue.
    Distemper is a crude form of tempera made by mixing dry pigment into a paste with water, which is thinned with heated glue in working or by adding pigment to whiting, a mixture of fine-ground chalk and size. It is used for stage scenery and full-size preparatory cartoons for murals and tapestries. When dry, its colours have the pale, mat, powdery quality of pastels, with a similar tendency to smudge. Indeed, damaged cartoons have been retouched with pastel chalks.
    Egg tempera is the most durable form of the medium, being generally unaffected by humidity and temperature. It dries quickly to form a tough film that acts as a protective skin to the support. In handling, in its diversity of transparent and opaque effects, and in the satin sheen of its finish, it resembles the modern acrylic resin emulsion paints.
    Traditional tempera painting is a lengthy process. Its supports are smooth surfaces, such as planed wood, fine set plaster, stone, paper, vellum, canvas, and modern composition boards of compressed wood or paper. Linen is generally glued to the surface of panel supports, additional strips masking the seams between braced wood planks. Gesso, a mixture of plaster of paris (or gypsum) with size, is the traditional ground. The first layer is of gesso grosso, a mixture of coarse, unslaked plaster and size. This provides a rough, absorbent surface for ten or more thin coats of gesso sotile, a smooth mixture of size and fine plaster previously slaked in water to retard drying. This laborious preparation results, however, in an opaque, brilliant white, light-reflecting surface, similar in texture to hard, flat icing sugar.
    The design for a large tempera painting traditionally was executed in distemper on a thick paper cartoon. The outlines were pricked with a perforating wheel so that when the cartoon was laid on the surface of the support, the linear pattern was transferred by dabbing, or "pouncing," the perforations with a muslin bag of powdered charcoal. The dotted contours traced through were then fixed in paint. Medieval tempera painters of panels and manuscripts made lavish use of gold leaf on backgrounds and for symbolic features, such as haloes and beams of heavenly light. Areas of the pounced design intended for gilding were first built up into low relief with gesso duro, the harder, less absorbent gesso compound used also for elaborate frame moldings. Background fields were often textured by impressing the gesso duro, before it set, with small, carved, intaglio wood blocks to create raised, pimpled, and quilted repeat patterns that glittered when gilded. Leaves of finely beaten gold were pressed onto a tacky mordant (adhesive compound) or over wet bole (reddish-brown earth pigment) that gave greater warmth and depth when the gilded areas were burnished.
    Colours were applied with sable brushes in successive broad sweeps or washes of semitransparent tempera. These dried quickly, preventing the subtle tonal gradations possible with watercolour washes or oil paint; effects of shaded modelling had therefore to be obtained by a crosshatching technique of fine brush strokes. According to the Italian painter Cennino Cennini, the early Renaissance tempera painters laid the colour washes across a fully modelled monochrome underpainting in terre vert (olive-green pigment), a method developed later into the mixed mediums technique of tempera underpainting followed by transparent oil glazes.
    The luminous gesso base of a tempera painting, combined with the accumulative effect of overlaid colour washes, produces a unique depth and intensity of colour. Tempera paints dry lighter in value, but their original tonality can be restored by subsequent waxing or varnishing. Other characteristic qualities of a tempera painting, resulting from its fast drying property and disciplined technique, are its steely lines and crisp edges, its meticulous detail and rich linear textures, and its overall emphasis upon a decorative flat pattern of bold colour masses.
    The great Byzantine tradition of tempera painting was developed in Italy in the 13th and 14th centuries by Duccio di Buoninsegna and Giotto. Their flattened picture space, generously enriched by fields and textures of gold leaf, was extended by the Renaissance depth perspectives in the paintings of Giovanni Bellini, Piero della Francesca, Carlo Crivelli, Sandro Botticelli, and Vittore Carpaccio. By that time, oil painting was already challenging the primacy of tempera, Botticelli and some of his contemporaries apparently adding oil to the tempera emulsion or overglazing it in oil colour.
    Following the supremacy of the oil medium during succeeding periods of Western painting, the 20th century saw a revival of tempera techniques by such U.S. artists as Ben Shahn, Andrew Wyeth, and George McNeil and by the British painter Edward Wadsworth. It would probably have been the medium also of the later hard-edge abstract painters had the new acrylic resin paints not proved more easily and quickly.
