The Theodosian church of St Sophia was destroyed on the first day of the great Nika rebellion of January 532. Its destruction provided Justinian with the pretext, at least, to rebuild it in a more durable and more magnificent form and presented his principal architects, Anthemius of Tralles and the elder Isidorus of Miletus, with an almost unprecedented opportunity. This opportunity they seized to the full. By a daring combination of structural forms never before attempted on such a scale, they created an interior whose superb spatial qualities still excite and amaze. A partial collapse in 558, little more than twenty years after the solemn dedication in December 537, showed that they had even been a little too daring and called for a partial reconstruction. But, after this had been completed by the younger Isidorus in 563, the rebuilt church acquired substantially its present form and remained for some 800 years the largest vaulted man-made structure in the world.
This paper is a slight expansion of part of the Annual Lecture delivered to the Society in January 1968. It is based on a continuing study of the church sponsored by the Dumbarton Oaks Centre for Byzantine Studies, Harvard University, and thanks are due to Dumbarton Oaks for permission to publish it; to Mr Robert L. Van Nice, whose measurements have been the essential starting point and whose intimate knowledge of the building has been made freely available throughout; to Professor Cyril Mango for translations of some of the documents; and to the Turkish authorities, particularly Bay Feridun Dirimtekin, Director of the Aya Sofya Museum, for their unfailing co-operation.

10 A figure of 20ft has been assumed as given by Malalas, though Theophanes and Cedrenus change this, in fact, to ‘more than 20ft’. In a later reference Malalas gives 30 ft, while Zonarus gives 25 ft.
