- Anthemios of Tralles
- SUBJECT AREA: Architecture and building[br]fl. sixth century AD Tralles, Lydia, Asia Minor[br]Greek architect, geometer, mathematician and physicist.[br]Tralles was a wealthy city in ancient Greece. Ruins of the city are situated on a plateau above the present-day Turkish city of Aydin, in Asia Minor, which is near to Ephesus. In 334 BC Tralles was used as a base by Alexander the Great and later it was occupied by the Romans. After the collapse of the western half of the Roman Empire in the fifth century AD Tralles remained a part of the Byzantine Empire until its destruction in 1282. Anthemios was one of the great sons of Tralles and was probably educated in Alexandria. He is especially famed as architect (with Isodorus of Miletos) of the great Church of Santa Sophia in Istanbul. This vast building, later a Turkish mosque and now a museum, was built for the Emperor Justinian between 532 and 537 AD. It was an early and, certainly for many centuries, the largest example of pendentive construction to support a dome. This form, using the spherical triangles of the pendentives, enabled a circular-based dome to be supported safely upon piers that stood on a square plan below. It gradually replaced the earlier squinch type of structure, though both forms of design stem from Middle Eastern origins. At Santa Sophia the dome rises to 180ft (55m) above floor level and has a diameter of over 100ft (30m). Together with Isodorus, Anthemios also worked upon the Church of the Holy Apostles in Istanbul.[br]Further ReadingG.L.Huxley, 1959, Anthemius of Tralles: A Study in Later Greek Geometry, Cambridge, Mass.: Harvard University Press.Procopius, 1913, De Aedificiis, On the Buildings Constructed by the Emperor Justinian, Leipzig.Richard Krautheimer, 1965, Early Christian and Byzantine Architcture, Penguin.DY
