Sesamos was a city in Paphlagonia that was eventually combined by Queen Amastris into the city of Amastris, along with its neighbor Kromna. Sesamos itself was mentioned by Homer, though we know very little about its history before being joined into Amastris.
Coins from Sesamos are rare.
300 BCE
The city of Amastris is founded by Amastris, a Persian princess and the niece of the Persian king Darius III. She establishes the city by combining four smaller settlements: Sesamos, Kytoros, Tios, and Kromna.
