Question

What was the original Greek name for Constantinople?

Answer

Byzantium

This is because the city had been called by several names over the centuries. Its original name was Lygos, probably a Thracian word, and then Byzantium when it became a Greek trading town. The Roman Emperor Septimus Severus renamed it Augusta Antonia after his son Antonius.
