Now these rivers flow down from the Phocian mountains, and among them the Cephissus, which takes its beginning at Lilaea, a Phocian city, as Homer says: "And those who held Lilaea, at the sources of Cephissus."1
And flowing through Elateia, the largest of the cities of Phocis, and through Parapotamii and Phanoteus,2
which are likewise Phocian towns, it goes on into Chaeroneia in Boeotia, and then through the territories of Orchomenus and Coroneia, and discharges into Lake Copais. And also the Permessus and the Olmeius, flowing from Helicon, meet one another and fall into the same Lake Copais near Haliartus; and also other streams empty into it. Now it is a large lake, having a circuit of three hundred and eighty stadia, but its outlets are nowhere to be seen, except for the fissure which admits the Cephissus, and for the marshes.
