Isidore of Miletus was one of the main Byzantine Greek architects that was commissioned by a Byzantine emperor, Justinian I. Also known as Justinian the Great or Saint Justinian the Great. Isidore of Miletus was commissioned specifically for Hagia Sophia. Aside from Hagia Sophia he presented the first completed collection of Archimedes’ works. Prior to the Hagia Sophia he was a famed mathematician and scientist. He was a part of the third bascilla. Side note: when the dome collapsed in 558 it is believed that Isidore of Miletus’s nephew, Isodorus the younger led the reconstruction.

Anthemius of Tralles was a Greek and son of Stephanus of Tralles a physician. Prior to partaking as an architect he was a geometer. It is said that he died in the early stages of Hagia Sophia around 534 but that is unconfirmed because it was said that the church was dedicated in 537. It is said that as a child he annoyed his neighbor by one, creating an artificial earthquake and two, by imitating lightening flashing in eyes.

Isidore of Miletus and Anthemius of Tralles were obviously directly related to Hagia Sophia because they were the architects in the third church built, the first two of which were destroyed. Justinian I wanted to guarantee that this one would no be destroyed, so it was built of stone. The second church being destroyed during the Nika Riot. Though these two men were not first architects, the knowledge and expertise they had in their respected fields proved to assist in their abilities to create and assist in building the Hagia Sophia. Another side note: hardly any of the websites, wiki, Britannica, and encyclopedia gave the exact same titles for the two men prior to becoming architects.
I chose these three images because while only reading about Hagia Sophia and not really pay attention to the pictures and only imagining the structure in my head I honestly did’t realize how different the structure would be in the present. Obviously I just wasn’t thinking about it but for some reason it was a small surprise seeing the structure in the present.
