Callidemus
Καλλίδημος
(Καλλίδημος), a Greek author about whom nothing is known, except that Pliny (Plin. Nat. 4.12) and Solinus (17) refer to him as their authority for the statement, that the island of Euboea was originally called Chalcis from the fact of brass (χαλκός) being discovered there first.
