Strabo VII. v. 8, describes this as
a rock that gives forth fire, and beneath it flow springs of warm water and asphalt — probably because the clods of asphalt in the earth are burned by the fire. And nearby, on a hill, is a mine of asphalt; and the part that is trenched is filled up again in the course of time, since, as Poseidonius says, the earth that is poured into the trenches changes to asphalt.
(tr. H. L. Jones, L.C.L.) Nymphs dancing about the fire appeared on coins of Apollonia. A convent preserved the religious association in recent times. The asphalt deposits are still worked, and leakage of gas sometimes supplies the fire.
