Pausanias Description of Greece 2.34.1

[1] Stretching out far into the sea from Troizenia is a peninsula, on the coast of which has been founded a little town called Methana. Here there is a sanctuary of Isis, and on the marketplace is a statue [ agalma] of Hermes, and also one of Hēraklēs. Some thirty stadium-lengths distant from the town are hot baths. They say that it was when Antigonos, son of Demetrios, was king of Macedon that the water first appeared, and that what appeared at once was not water, but fire that gushed in great volume from the ground, and when this died down the water flowed; indeed, even at the present day it wells up hot and exceedingly salt. A bather here finds no cold water at hand, and if he dives into the sea his swim is full of danger. For wild creatures live in it, and it swarms with sharks.
