Genius (mythology)
In Roman mythology, every person had either a genius (for men) or a juno for women. Juno was also the name for the queen of the gods.
Originally, the genius/juno were ancestors who guarded over their descendants. Over time, they turned into personal guardian spirits, granting intellect and prowess. Sacrifices were made to one's genius/juno on one's birthday.
The juno was worshipped under many titles: Iugalis - protected marriage Matronalis - protected married women Pronuba - protected the bride Virginalis - protected virginity
In addition to the genius/juno of individuals, regions, familes, households and cities each had a genius. The genius of the Roman race was a winged, naked youth. The genius dedicated to places were usually depicted as snakes.
