“We believe this surgery was performed due to a headache or a problem that had to do with the skull,” Kızıl said.

Euromus was an Ancient Greek city whose ruins are approximately 12 km northwest of Milas. The city was a member of the Chrysaorian League and minted its own coins from the 2nd Century BC.

Among the ruins is a temple of Zeus Lepsinos from the reign of Emperor Hadrian.
