Genius (mythology)
The genius of Roman religion was a spirit that someone could imagine tempted to steal. In the plays of Plautus, one character mocks another man's father as so stingy that he uses cheap Samian ware for sacrifices to his own genius. The miser's reasoning is that a worthless dish gives the spirit nothing to pocket. The joke only works because the genius is not simply the man himself, yet it shares his greed. So what was this companion that Romans honored with offerings? How did a private guardian spirit grow into something that touched emperors, armies, and coinage? And why did a Christian emperor eventually decide that honoring it was a crime?
From the hour of his birth until the day he died, a Roman man was accompanied by his genius. The genius was the individual instance of a general divine nature that was present in every person, place, or thing. Much like a guardian angel, it stayed at his side. Women had a counterpart, the Juno spirit, which followed each of them in the same way.
The idea reached well beyond people. Each place had its own genius, called the genius loci, and so did powerful objects such as volcanoes. There were genii of particular activities too. The genius of the theatre made performances succeed, the genius of vineyards made grapes grow, and the genius of festivals made celebrations go well.
For the Romans it was extremely important to propitiate the right genii before the major undertakings and events of life. One reading of this habit is that people, feeling something higher than their own limited selves, honored that presence with offerings as a god. In doing so they made up for a vague sense of their own divine origin.
The Christian theologian Augustine later equated the Christian soul with the Roman genius. He cited Varro as attributing every human being's rational powers and abilities to their genius.
Doors, gates, and streets each had a genius of their own. So did districts, tribes, and houses. The term could be applied to almost any divinity, but it was used most often for the smallest units of society and settlement. Families and their homes were the typical cases, along with people not generally known. Higher-level and state genii more often had well-established names.
The Romans pictured even their supreme gods as a human family. Jupiter was the father and the supreme divine unity, and Juno was the mother and queen of the gods. These supreme figures were divided into a genius for each individual family. The male power in a household was therefore a Jupiter. The genius of each woman, representing female reproductive power, was a Juno.
The Juno was worshipped under many titles. Iugalis meant "of marriage" and Matronalis meant "of married women". Pronuba meant "of brides" and Virginalis meant "of virginity".
Genii were often seen as protectors, which is why people propitiated them. To guard an infant, a family approached several deities of birth and childrearing. Cuba was the spirit of "lying down to sleep", Cunina of the cradle, and Rumina of breast-feeding. If these spirits failed in their duties, the baby would be in danger. The best surviving evidence for how families honored such protectors comes from the houses of Pompeii.
Hundreds of lararia, or family shrines, have been found at Pompeii. They usually stood off the atrium, the kitchen, or the garden. These spots had an opening in the roof, so the smoke of burnt offerings could escape.
Each shrine carries a panel fresco built on the same theme. Two figures at the edges, the Lares, attend a central figure who is the family genius. In some paintings the center holds two figures instead, a genius and a juno. They may or may not stand at an altar.
In the foreground, one or two serpents crawl through a meadow toward the genius. The snake was not only a painted motif. Campania and Calabria preserved an ancient custom of keeping a propitious house snake, and that animal was linked with the genius.
The English word genius was borrowed from Latin, where it meant "household guardian spirit". At an earlier stage it meant the "innate male power of a race or clan". Its ultimate source is the Indo-European root *g̑enh₁-, meaning "give birth, produce". The same root appears in Latin gignō, "give birth", and in gēns, gentis, "tribe, people".
The Roman poet Horace gave a famously compact description of the spirit. He called it "the companion which controls the natal star; the god of human nature, in that he is mortal for each person, with a changing expression, white or black". On this view the genius shares a person's mortality and shows a different face to each person.
Horace was writing at the moment when the first emperor was introducing the cult of his own genius.
After the final victory of the Roman Civil War at the Battle of Actium, Octavius Caesar returned to Rome. To the Senate he seemed a man of great power and success, which they took as a clear mark of divinity. In recognition of this prodigy, they voted that every banquet should include a libation to his genius.
He accepted the mood by choosing the name Augustus. The name captured the numinous sense of the English word "august". The household cult of the Genius Augusti dates from this period. Families honored it at every meal, alongside their other household numina.
This began the Roman imperial cult, in which people cultivated the genius of the emperor rather than the man himself. It was a clever distinction, since it let Romans offer worship without calling a living person a god.
A denarius from Spain, dated 76-75 BC, bears a bust of the GPR on its obverse. GPR stands for Genius Populi Romani, the "Genius of the Roman People". Coins often used the genius of a whole social body as a small supporting image.
An aureus from Siscia in Croatia, dated 270-275 AD, shows a standing figure on its reverse. The legend reads GENIUS ILLVR, short for Genius Exercitus Illyriciani, the "Genius of the Illyrian Army".
An aureus from Rome, dated 134-138 AD, shows a youth holding a cornucopia and a patera, a sacrificial dish. The reverse inscription reads GENIOPR, meaning genio populi Romani, "to the genius of the Roman people". The same kind of shorthand filled stone inscriptions across the empire.
If the genius of the imperator, the commander of all troops, deserved offerings, so did every unit under his command. Roman Britain has yielded altars to the genii of Roma, Roma aeterna, and Britannia. Others honor every legion, cohors, ala, and centuria in Britain. There are altars to the praetorium of every castra, and even to the vexillae.
Dedications to genius were not limited to soldiers. Under the empire, Gallia Cisalpina produced many for people of authority and respect. Beside the emperor's genius principis stood the genii of patrons of freedmen, owners of slaves, and patrons of guilds. Philanthropists, officials, villages, other divinities, relatives, and friends received them too. Some dedications were joined with other words, such as "to the genius and honor". For couples the wording was "to the genius and Juno".
Hundreds of dedicatory, votive, and sepulchral inscriptions from across the empire show the cult flourishing officially. Stock phrases were abbreviated. GPR meant genio populi Romani, "to the genius of the Roman people". GHL meant genio huius loci, "to the genius of this place". GDN meant genio domini nostri, "to the genius of our master".
In 392 AD, after the final victory of Christianity, Theodosius I declared veneration of the genii, Lares, and Penates to be treason. That ended their official standing. The idea itself lived on, in imagery and in everyday speech, under different names or with accepted modifications.
