One of two things has taken place: either the cities have remained unremoved, when the increase in the waters has been insufficient to overflow the dwellings because of their elevation, or else they have been abandoned and rebuilt elsewhere, when, being oftentimes endangered by their nearness to the lake, they have relieved themselves from fear by changing to districts farther away or higher up. And it follows that the cities thus rebuilt which have kept the same name, though at first called by names truly applying to them, derived from local circumstances, have names which no longer truly apply to them; for instance, it is probable that "Plataeae" was so called from the "blade"1
of the oars, and "Plataeans" were those who made their living from rowing; but now, since they live far away from the lake, the name can no longer truly apply to them. Helos and Heleon and Heilesium were so called because they were situated near marshes;2
but now the case is different with these places, since they have been rebuilt elsewhere, or else the lake has been greatly reduced because of outflows that later took place; for this is possible.
