Stephanos of Byzantium - Ethnika
Thyateira: a city of Lydia, formerly Pelopeia and Semiramis. From Seleukos Nikator, who, while warring against Lysimachos and hearing that a daughter had been born to him, called the city Thygateira; and it ought to be feminine, but now they say it in the neuter. It was also called the Last of the Mysians. When the Mysians wished to found a city, the god answered that they should found it where a hind should be seen shot with an arrow and running, and having found it to name it from the hind's rushing and running. The ethnonym Thyateirenos, as 'Gangra' 'Gangrenos'. From it Nikandros the grammarian, Thyateirenian.
