A Discourse on the Worship of Priapus, and Its Connexion with the Mystic Theology of the Ancients. Richard Payne Knight, esq. London: R.P. Knight, 1865
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 effigies 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 English word “fascinate” ultimately derives from Latin fascinumand the related verb fascinare, “to use the power of the fascinus,” that is, “to practice magic” and hence “to enchant, bewitch.”
