The governor ordered the saint to be sent to the city of Perinthus, and from there to Byzantium, where St Mocius was beheaded.

[2][3] The Emperor Anastasius I Dicorus (491-518) built an open air cistern, to supply water to the city of Constantinople (today's Istanbul).

It is the third of the Late Roman Period cisterns and the largest in the city, named after the saint who was venerated in a nearby church.

[4] A church dedicated to saint Mocius is said to have been built by Constantine I on top of a temple of Zeus.

It was located between the Theodosian and Constantinian walls, perhaps to the west of the cistern named after the saint and close to the monastery of Theotokos ta Mikra Romaiou.
