These rivers descend from the Phocian mountains, and among them the Cephissus,1 having its source at Lilæa, a Phocian city, as Homer describes it;
It flows through Elateia,3 the largest of the cities among the Phocians, through the Parapotamii, and the Phanoteis, which are also Phocian towns; it then goes onwards to Chæroneia in Bœotia; afterwards, it traverses the districts of Orchomenus and Coroneia, and discharges its waters into the lake Copais. The Permessus and the Olmeius4 descend from Helicon, and uniting their streams, fall into the lake Copais near Haliartus. The waters of other streams likewise discharge themselves into it. It is a large lake with a circuit of 380 stadia;5 the outlets are nowhere visible, if we except the chasm which receives the Cephissus, and the marshes.
