Side (Laconia)

After the peak there runs into the land the Gulf of Boeae, and the city of Boeae is at the head of the gulf. This was founded by Boeus, one of the Heracleidae, and he is said to have collected inhabitants for it from three cities, Etis, Aphrodisias and Side. Of the ancient cities two are said to have been founded by Aeneas when he was fleeing to Italy and had been driven into this gulf by storms. Etias, they allege, was a daughter of Aeneas. The third city they say was named after Side, daughter of Danaus¹.
