Justinian Surpasses Solomon

On December 27, 537, Emperor Justinian inaugurates Hagia Sophia in Constantinople and, according to chronicle, exclaims: "Solomon, I have surpassed you!" Architects Anthemius of Tralles and Isidore of Miletus have just completed unprecedented audacity: a thirty-one-meter dome resting on a square of pendentive vaults. The single nave, bathed in light filtered through forty windows at the dome's base, impresses to the point that witnesses believe the dome suspended by a golden chain. Twenty-one years later, an earthquake collapses this first dome; it will be rebuilt in 562, higher.

Justinian reigns over a partly reconquered empire — Italy, North Africa — and obsessed with restoring Roman grandeur. Hagia Sophia, erected in only five years on the site of a previous burned basilica, must embody this imperial renaissance. Ten thousand workers and a hundred master builders mobilize marbles from across the Mediterranean: Egyptian porphyry, Thessalian green, Proconnesian white.

Anthemius, mathematician and engineer, and Isidore, vault specialist, experiment with geometry where the dome's weight is redistributed toward massive piers by lateral half-domes. The result gives illusion of floating surface — effect reinforced by rows of windows piercing the dome's base.

The 558 collapse, after an earthquake, kills Isidore the Younger, nephew of the first architect, who takes over the project. The new dome, slightly more elevated and reinforced by external buttresses still visible today, becomes the model for great Byzantine then Ottoman domes.

For nearly a thousand years, until Saint Peter's construction in Rome, Hagia Sophia remains the vastest Christian cathedral in the world. Converted into mosque in 1453, then museum in 1934, it remains the symbol of a city where empires and religions overlap without erasing Justinian's voice.
