Fascinum

In ancient Roman religion and magic, the fascinus or fascinum was the embodiment of the divine phallus. The word can refer to the deity himself (Fascinus), to phallus and amulets, and to the spells used to invoke his divine protection.Pliny calls it a medicus invidiae, a "doctor" or remedy for envy (invidia, a "looking upon") or the evil eye.

The Vestal Virgins tended the cult of the fascinus populi Romani, the sacred image of the phallus that was one of the tokens of the safety of the state (sacra Romana). It was thus associated with the Palladium.Roman myths, such as the begetting of Servius Tullius, suggest that this phallus was an embodiment of a masculine generative power located within the hearth, regarded as sacred. When a general celebrated a triumph, the Vestals hung an effigy of the fascinus on the underside of his chariot to protect him from invidia.

Augustine, whose primary source on Roman religion was the lost theological works of Marcus Terentius Varro, notes that a phallic image was carried in procession annually at the festival of Father Liber, the Roman god identified with Dionysus or Bacchus, for the purpose of protecting the fields from fascinatio, magic compulsion:

Varro says that certain rites of Liber were celebrated in Italy which were of such unrestrained wickedness that the shameful parts of the male were worshipped at crossroads in his honour. … For, during the days of the festival of Liber, this obscene member, placed on a little trolley, was first exhibited with great honour at the crossroads in the countryside, and then conveyed into the city itself. … In this way, it seems, the god Liber was to be propitiated, in order to secure the growth of seeds and to repel enchantment (fascinatio) from the fields.
