An ancient city of northwest Asia Minor near the Bosporus in present-day Turkey. Founded in 264 BC on the site of an earlier city, it flourished for many centuries. Around AD 286, Diocletian made Nicomedia the capital of the eastern portion of the Roman Empire, but it was soon superseded by Byzantium.
The better sources make Sardica the scene of meeting and name Eusebius (of Nicomedia) as the prelate who attended Constantine.
He was buried in the great Armenian cemetery at Nicomedia, but in the course of 1906 his relics were transferred to Hungary.
Other writers are Aaron (the elder) ben Joseph, 13th century, who wrote the commentary Sepher ha-mibhhar; Aaron (the younger) of Nicomedia (14th century), author of `E Ilayyim, on philosophy, Gan `Eden, on law, and the commentary Kether Torah; in the 15th century Elijah Bashyazi, on law (Addereth Eliyahu), and Caleb Efendipoulo, poet and theologian; in the 16th century Moses Bashyazi, theologian.
He enlarged and consolidated the kingdom, founded the great city of Nicomedia as the capital, and fought successfully for some time with Antiochus of Syria.
We find him again in Nicomedia, in Athens, and twice in Arabia.
