Ovid's "Metamorphoses" provides an earlier source for the same etymology. Ovid describes how Juno orders the goddess of childbirth, Lucina, to prevent Alcmene from giving birth to Hercules. Alcmene's servant Galanthis, realizing that Lucina is outside the room using magic to prevent the birth, emerges to announce that the birth has been a success. Lucina, in her amazement, drops the spells of binding and Hercules is born. Galanthis then mocks Lucina, who responds by transforming her into a weasel. Ovid writes (in A.S. Kline's translation) "And because her lying mouth helped in childbirth, she a weasel gives birth through her mouth."
