The speculations as to who and what Canidia was, in which scholars have run riot, are conspicuous for absurdity, even among the wild and ridiculous conjectures as to the personages named by Horace in which the commentators have indulged. That some well-known person was the original of Canidia is extremely probable, for professors of witchcraft abounded at the time, combining very frequently, like their modern successors, the arts of Medea with the attributes of Dame Quickly. What more natural than for a young poet to work up an effective picture out of the abundant suggestions which the current stories of such creatures and their doings presented to his hand? The popular belief in their power, the picturesque conditions under which their spells were wrought, the wild passions in which lay the secret of their hold upon the credulity of their victims, offered to the Roman poet, just as they did to our own Elizabethan dramatists, a combination of materials most favourable for poetic treatment. But that Horace had, as many of his critics contend, a feeling of personal vanity, the pique of a discarded lover, to avenge, is an assumption wholly without warrant. He was the last man, at any time or under any circumstances, to have had any relations of a personal nature with a woman of Canidia's class. However inclined he may have been to use her and her practices for poetic purposes, he manifestly not only saw through the absurdity of her pretensions, but laughed at her miserable impotence, and meant that others should do the same. It seems to be impossible to read the 8th of his First Book of his Satires, and not come to this conclusion. That satire consists of the monologue of a garden god, set up in the garden which Maecenas had begun to lay out on the Esquiline Hill. This spot had until recently been the burial-ground of the Roman poor, a quarter noisome by day, and the haunt of thieves and beasts of prey by night. On this obscene spot, littered with skulls and dead men's bones, Canidia and her accomplice Sagana are again introduced, digging a pit with their nails, into which they pour the blood of a coal-black ewe, which they had previously torn limb-meal, "So to evoke the shade and soul Of dead men, and from these to wring Responses to their questioning." They have with them two effigies, one of wax and the other of wool--the latter the larger of the two, and overbearing the other, which cowers before it, "Like one that stands Beseeching in the hangman's hands. On Hecate one, Tisiphone The other calls; and you might see Serpents and hell-hounds thread the dark, Whilst, these vile orgies not to mark, The moon, all bloody red of hue, Behind the massive tombs withdrew."
