Polybius tells us that one of the three
craters of the island has partly fallen down, while the larger of the
two that remain has a lip, the circumference of which is five stadia,
and the diameter nearly 50 feet,[2362] and its elevation about a stadium
from the level of the sea, which may be seen at the base in calm
weather; but if we are to credit this, we may as well attend to what has
been           concerning Empedocles.
