[Verginius Rufus]

That should be Klazomenai (Clazomenae). It used to be an island just off the coast until Alexander the Great connected it to the mainland with a causeway. It was the birthplace of the pre-Socratic philosopher Anaxagoras.

Thanks VR. > Klazomenai is located in modern Urla (Vourla in Greek) on the western coast of Anatolia, on the southern coast of the Gulf of İzmir, at about 20 miles west of İzmir. The city was originally located on the mainland, but probably during the early fifth-century Ionian Revolt from the Persians, it was moved to an island just off the coast, which Alexander the Great eventually connected to the mainland with a causeway. -- https://www.princeton.edu/~achaney/tmve/wiki100k/docs/Klazomenai.html
