Note 143 — LIFE OF CICERO.
George Long translation
Glaucus was a fisherman of Anthedon in Bœotia. After eating of a certain herb he jumped into the sea and became a sea-god with the power of prophecy (Pausanias, ix. 22). Strabo (p. 405, ed. Casaub.) says that he became a fish of some kind (κῆτος), a change more appropriate to his new element, though perhaps not to his new vocation. Æschylus made a drama on the subject, which Cicero may have used.
