In Etruria there is said to be a certain island named Aethaleia, in which out of a certain mine in former days copper was dug, from which they say that all the copper vessels among them have been wrought; that afterwards it could no longer be found: but, when a long interval of time had elapsed, from the same mine iron was produced, which the Etrurians, who inhabit the town called Populonium, use to the present day.
