MEDICINE Plague in the city of Aegina told in Ovid's "Metamorphoses". The pestilence; unleashed by Hera to punish the loves of Zeus with the eponymous nymph of the city; only spared King Aeacus; son of the naiad and of Zeus himself; to repopulate the kingdom of his son; the divine father transformed ants into men; giving rise to the Myrmidons.
