may contain the first examples of trompe-l'œil, pseudo-perspective, and pure landscape. Almost all of the surviving painted portraits from the Ancient world are a large number of coffin-portraits of bust form found in the Late Antique cemetery of Al-Fayum. They give an idea of the quality that the finest ancient work must have had. A very small number of miniatures from Late Antique illustrated books also survive, and a rather larger number of copies of them from the Early Medieval period. Early Christian art grew out of Roman popular, and later Imperial, art and adapted its iconography from these sources. Medieval Most surviving art from the Medieval period was religious in focus, often funded by the Church, powerful ecclesiastical individuals such as bishops, communal groups such as abbeys, or wealthy secular patrons. Many had specific liturgical functions—processional crosses and altarpieces, for example. One of the central questions about Medieval art concerns its lack of realism. A great deal of knowledge of perspective in art and understanding of the human figure was lost with the fall of Rome. But realism was not the primary concern of Medieval artists. They were simply trying to send a religious message, a task which demands clear iconic images instead of precisely rendered ones. Time Period: 6th century to 15th century Early Medieval art Migration period art is a general term for the art of the "barbarian" peoples who moved into formerly Roman territories. Celtic art in the 7th and 8th centuries saw a fusion with Germanic traditions through contact with the Anglo-Saxons creating what is called the Hiberno-Saxon style or Insular art, which was to be highly influential on the rest of the Middle Ages. Merovingian art describes the art of the Franks before about 800, when Carolingian art combined insular influences with a self-conscious classical revival, developing into Ottonian art. Anglo-Saxon art is the art of England after the Insular period. Illuminated manuscripts contain nearly all the surviving painting of the period, but architecture, metalwork and small carved work in wood or ivory were also important media. Byzantine Byzantine art overlaps with or merges with what we call Early Christian art until the iconoclasm period of 730-843 when the vast majority of artwork with figures was destroyed; so little remains that today any discovery sheds new understanding. After 843 until 1453 there is a clear Byzantine art tradition. It is often the finest art
