Anthemius of Tralles ( c. 474 – before 558 ; ) was a Greek professor of Geometry in Constantinople ( present-day Istanbul in Turkey ) and architect, who collaborated with Isidore of Miletus to build the church of Hagia Sophia by the order of Justinian I. Anthemius came from an educated family, one of five sons of Stephanus of Tralles, a physician.

Successful recreations have been performed by Anthemius of Tralles ( 6th century AD ), Proclus ( 6th century ) ( who by this means purportedly destroyed the fleet of Vitellus besieging Constantinople ), Ibn Sahl in his On Burning Mirrors and Lenses ( 10th century ), Alhazen in his Book of Optics ( 1021 ), Roger Bacon ( 13th century ), Giambattista della Porta and his friends ( 16th century ), Athanasius Kircher and Gaspar Schott ( 17th century ), the Comte du Buffon in 1740 in Paris, Ioannis Sakas in the 1970s in Greece, and others.

Justinian commissioned Anthemius of Tralles and Isidore of Miletus to replace it with a new and incomparable St Sophia.

Isidore of Miletus was one of the two main Byzantine Greek architects ( Anthemius of Tralles was the other ) that Emperor Justinian I commissioned to design the church of Hagia Sophia in Constantinople from 532-537A. D.

Isidore of Miletus and Anthemius of Tralles originally planned on a main hall of the Hagia Sophia that measured 230 feet by 250 feet, making it the largest church in Constantinople, but the original dome was nearly 20 feet lower than it was constructed, “ Justinian suppressed these riots and took the opportunity of marking his victory by erecting in 532-7 the new Hagia Sophia, one of the largest, most lavish, and most expensive buildings of all time .” Although Isidore of Miletus and Anthemius of Tralles were not formally educated in architecture, they were scientists that could organize the logistics of drawing thousands of laborers and unprecedented loads of rare raw materials from around the Roman Empire to create the Hagia Sophia for Emperor Justinian I.

Most notably, he had the Hagia Sophia, originally a basilica style church that had been burnt down during the Nika riots, splendidly rebuilt according to a completely different ground plan, under the architectural supervision of Isidore of Miletus and Anthemius of Tralles.

In the 6th century AD, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments, Ibn al-Haytham ( Alhazen ) ( 965 – 1040 ) studied the camera obscura and pinhole camera, Albertus Magnus ( 1193 – 1280 ) discovered silver nitrate, and Georges Fabricius ( 1516 – 71 ) discovered silver chloride.

Built by Anthemius of Tralles and Isidore of Miletus in Constantinople between 532 and 537, the Hagia Sophia has been called the greatest building in the world.

Isidore of Miletus and Anthemius of Tralles, the architects of the famous Hagia Sophia in Constantinople, also contributed towards mathematical theories concerning architectural form, and the perceived mathematical harmony needed to create a multi-domed structure.
