Location information

Cephisus

   A celebrated river of Greece, that rises at the foot of Parnassus, close to Lilaea, and, after traversing the plains of Phocis and part of the Boeotian territory, empties into the Copaic Lake in the latter country. Hesiod compares it to a serpent, from the many sinuosities of its course. The modern name is Mauro Potamo. According to the poets, the son of the river-god Cephissus introduced the worship of the Graces into Boeotia, and hence the peculiar attachment which they were said to have for the waters of this stream.
