ABSTRACT
Thales was the first known great Greek mathematician and lived in the sixth century BC. He came up with a method of mathematical thinking that became standard for later Greek mathematics. The two mathematicians, Isidore and Anthemius, joined forces to build the church dedicated to the Holy Wisdom to celebrate not only the rule of Christianity in the Roman Empire with Byzantium at its center, but also the political and military prowess of the Empire with Justianian I at its head. The other architect of Hagia Sophia, Isidore, must have known of Thales too. After all, he was born in the same town from which Thales came. The Milesian school was very important school that brought together knowledge that existed in Babylonia and Egypt, particularly that related to mathematics and astronomy, and made it part of the Hellenic intellectual heritage.
