Ovid tells in Fasti (II, 583-586) that the nymph Lara warned her sister Juturna against Jupiter and his lascivious conduct. She said it to Juno too. Jupiter was angry and he had Lara’s tongue amputated too. Therefore, Lara was sentenced to eternal silence. Jupiter ordered Mercury to guide her to Manes, the place of silenced people. On the way to hell, Lara (now Tacita Muta) was raped by the god of commerce and travellers. Two twins were born (Lares) as a result of this union. In the interpretation of this patriarchal myth, Lares are protectors of the home. Lara was punished for making use of man's right to speak.
