Never before had the citizens of the Roman Empire seen such construction, at such a pace. The dusty city of the emperor’s birth, Tauresium, was refurbished and renamed Justiniana Prime; hospitals and baths sprang up, and fortifications were strengthened. Bridges spanning mighty rivers were constructed, and inns were spaced along the major highways for the imperial post to change horses. The most impressive work, however, was saved for Constantinople. A sumptuous new Senate house, colonnaded with creamy white marble pillars and topped with fine carvings, rose near the city’s central square to replace the burned one. Three statues of barbarian kings were set up, all bowing before a large column surmounted with an equine statue of Justinian in full military dress.*
To the west of his column, the emperor built a massive subterranean cistern to feed the city’s numerous fountains and baths and to provide fresh water for all of its inhabitants. Constantinople gleamed with new construction, but, for the emperor, this was merely the prologue. He now turned to the project which would surpass them all.The Hagia Sophia was undoubtedly the most important structure that had been destroyed in the riots. Originally built by Constantius II to house the mystery of the Holy Communion, it had been demolished by rioters more than a century before when the great golden-tongued reformer Saint John Chrysostom had been exiled to Georgia. The emperor Theodosius II had rebuilt it eleven years later along the same rather uninspired lines, and most in the city assumed that the familiar outline would soon greet them once again. Justinian, however, had no intention of following the tired plans of an earlier age. This was a chance to remake the cathedral on a whole new scale, something worthy of his vision for the empire. It was to be nothing short of a revolution, equal parts art and architecture, the enduring grandeur of the emperor himself frozen in marble and brick.
Little more than a month after the Nika riots, construction began on the mighty showpiece of his reign. Choosing two architects who had more vision than practical experience, Justinian told them to create a building unlike anything else in the world. Sheer scale wasn’t enough—the empire was full of grand monuments and immense sculpture. This had to be something different, something fitting for the new golden age that was dawning. Expense, he informed them, wasn’t an issue, but speed was. He was already in his fifties, and he didn’t intend to have some successor apply the final coat of paint and claim it as his own.
The two architects didn’t disappoint. Rejecting the classical basilica form that had been used for three hundred years, they came up with a bold and innovative plan.*
Building the largest unsupported dome in the world, they put it on a square floor plan and distributed its weight over a cascading series of half-domes and cupolas. The riches of the empire were poured into its construction. Each day, gold arrived from Egypt, porphyry from Ephesus, powdered white marble from Greece, and precious stones from Syria and North Africa. Even the old capital provided a quarry for the new, as columns that had once stood in the Temple of the Sun in Rome were carted off to adorn the rising church.The building seemed to grow at a breathtaking rate. The architects split their crew of ten thousand men into two parts, placing one group at the south end and the other at the north end. Spurred on by the presence of the emperor—who daily visited the site—the two teams raced against each other, speeding up the building to a frenetic pace. In the end, it took only five years, ten months, and four days from the laying of the first stone to the completion of the building—a remarkable achievement in any age, much less one without modern machines.†
