GENIUS,
A Divinity, whom ancient Phllosophers esteemed to be the Son of God, and the Father of Men. They allowed a Ge∣nius or Intelligence to each Province, Town and Person, who took care of the Affairs of this World. They allowed also Genius's to Forests, Fountains, Trees, Eloquence, Sciences, and Joy, and it appears by several Medals, particularly one of Nero, GENIO AUGUSTI, GENIO SENATUS, GENIO P. ROMANI, GENIO EXERCITUUM, Upon these Medals the figure of God Genius is represented veiled at the middle of the Body, holding with one hand a Horn of Plenty, and with the other a Cup for the Sacrifice; and before the Sta∣tue there was an Altar, and a Fire thereon. Which agrees with the description that Am∣mianus Marcellinus has given us of the same, in the 25th Book of the Emperor Julianus's Deeds.
Censorinus in his Book intituled de Die Natali, says, that as soon as Men are born, they are put under the tuition of God Genius; and Euclid tells us, that Men have two Genins's, one good and the other bad. Plutarch relates in the life of Brutus, that he saw by night in a Dream a Fantome, by the light of a Lamp that was in his Chamber, and having asked him who he was, he answer'd him, that he was his bad Genius.
Each person offered Sacrifice every year to his Genius, and particularly upon Birth-days, with leven and salted Dough; and some∣times with a Pig two months old, and scattered Flowers and sprinkled Wine to him: and the Sacrifice being over, they made a great Feast for their Friends, and thus the Comedi∣ans was called Genio indulgere, or Genio volupe facere.
In the beginning it was not permitted to swear by the Genius of the Prince; but after∣wards the most solemn Oaths, were those that were sworn by the Genius of the Empe∣ror; and Suetonius assures, that Caligula put many to death, because they refused to swear by his Genius.
Apuleius has writ a Treatise of the Genius or evil Spirit of Socrates. The name of Ge∣nius among some who call themselves Chri∣stians, is given to the good Angels attending Men or States.
