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, 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 or the evil eye.
Etymology
The English word "" ultimately derives from Latin and the related verb fascinare, "to use the power of the fascinus", that is, "to practice magic" and hence "to enchant, bewitch". Catullus uses the verb at the end of Carmen 7, a hendecasyllabic poem addressing his lover Lesbia; he expresses his infinite desire for kisses that cannot be counted by voyeurs nor "fascinated" by a malicious tongue; such bliss, as also in Carmen 5, potentially attracts invidia. Fescennine Verses, the satiric and often lewd songs or chants performed on various social occasions, may have been so-named from the fascinum; ancient sources propose this etymology along with an alternative origin from Fescennia, a small town in Etruria.
Phallic charms, often winged, were ubiquitous in Roman culture, appearing as objects of jewellery such as pendants and finger rings, relief carvings, lamps, and wind chimes. Fascinus was thought particularly to ward off evil from children, mainly boys, and from conquering generals. The protective function of the phallus is usually related to the virile and regenerative powers of an erect phallus, though in most cases the emotion, shame, or laughter created by obscenity is the power that diverts the evil eye. There are very few Roman images of people wearing a phallic charm. Varro notes the custom of hanging a phallic charm on a baby's neck, and examples have been found of phallus-bearing rings too small to be worn except by children. A 2017 experimental archaeology project suggested that some types of phallic pendant were designed to remain pointing outwards, in the direction of travel of the wearer, in order to face towards any potential danger or bad luck and nullify it before it could affect the wearer. Other symbols may have been interchangeable with the phallus, such as the club of Hercules. The victory of the phallus over the power of the evil eye may be represented by the phallus ejaculating towards a disembodied eye. This motif is shown in several examples of Roman art. For example, the motif is known from multiple relief sculptures from Leptis Magna in present-day Libya, as well as several instances on Hadrian's Wall. A 1st-century BC terracotta figurine shows "two little phallus-men sawing an eyeball in half". The "fist and phallus" amulet was prevalent amongst soldiers. These are phallic pendants with a representation of a clenched fist at the bottom of the shaft, facing away from the glans. Several examples show the fist making the manus fica or "fig sign", a symbol of good luck. The largest known collection comes from Camulodunum. Some examples of the fist-and-phallus amulets incorporate vulvate imagery as well as an extra apotropaic device.
