Gibbon observes of the Roman superstition on the authority of Petronius, that it may be inferred that it was of Italian rather than barbaric extraction. Etruria furnished the people of Romulus with the science of divination. Early in the history of the Republic the law is very explicit on the subject of witchcraft. In the decemviral code the extreme penalty is attached to the crime of witchcraft or conjuration: 'Let him be capitally punished who shall have bewitched the fruits of the earth, or by either kind of conjuration (excantando neque incantando) shall have conjured away his neighbour's corn into his own field,' &c., an enactment sneered at in Justinian's Institutes in Seneca's words. A rude and ignorant antiquity, repeat the lawyers of Justinian, had believed that rain and storms might be attracted or repelled by means of spells or charms, the impossibility of which has no need to be explained by any school of philosophy. A hundred and fifty years later than the legislation of the decemvirs was passed the Lex Cornelia, usually cited as directed against sorcery: but while involving possibly the more shadowy crime, it seems to have been levelled against the more 'substantial poison.' The conviction and condemnation of 170 Roman ladies for poisoning, under pretence of incantation, was the occasion and cause. Sulla, when dictator, revived this act de veneficiis et malis sacrificiis, for breach of which the penalty was 'interdiction of fire and water.' Senatorial anathemas, or even those of the prince, were ineffective to check the continually increasing abuses, which towards the end of the first century of the empire had reached an alarming height.21
A general degradation of morals is often accompanied, it has been justly remarked, by a corresponding increase of the wildest credulity, and by an abject subservience to external religious rites in propitiation of an incensed deity. It was thus at Rome when the eloquence of Cicero, and afterwards the indignant satire of Juvenal or the calm ridicule of the philosophic Lucian,22 attempted to assert the 'proper authority of reason.' To speak the truth, says Cicero, superstition has spread like a torrent over the entire globe, oppressing the minds and intellects of almost all men and seizing upon the weakness of human nature.23 The historian of 'The Decline and Fall of the Roman Empire' justifies and illustrates this lament of the philosopher of the Republic in the particular case of witchcraft. 'The nations and the sects of the Roman world admitted with equal credulity and similar abhorrence the reality of that infernal art which was able to control the eternal order of the planets, and the voluntary operations of the human mind. They dreaded the mysterious power of spells and incantations, of potent herbs and execrable rites, which could extinguish or recall life, influence the passions of the soul, blast the works of creation, and extort from the reluctant demons the secrets of Futurity. They believed with the wildest inconsistency that the preternatural dominion of the the air, of earth, and of hell, was exercised from the vilest motives of malice or gain by some wrinkled hags or itinerant sorcerers who passed their obscure lives in penury and contempt. Such vain terrors disturbed the peace of society and the happiness of individuals; and the harmless flame which insensibly melted a waxen image might derive a powerful and pernicious energy from the affrighted fancy of the person whom it was maliciously designed to represent. From the infusion of those herbs which were supposed to possess a supernatural influence, it was an easy step to the case of more substantial poison; and the folly of mankind sometimes became the instrument and the mask of the most atrocious crimes.'24
Latin poetry of the Augustan and succeeding period abounds with illustrations, and the witches of Horace, Ovid, and Lucan are the famous classical types.25 Propertius has characterised the Striga as 'daring enough to impose laws upon the moon bewitched by her spells;' while Petronius makes his witch, as potent as Strepsiades' Thessalian sorceress, exclaim that the very form of the moon herself is compelled to descend from her position in the universe at her command. For the various compositions and incantations in common use, it must be sufficient to refer to the pages of the Roman poets. The forms of incantation and horrid rites of the Horatian Sagana Canidia (Epod. v. and Sat. i. 8), or the scenes described by the pompous verses of the poet of the civil war (De Bello Civili, vi.), where all nature is subservient, are of a similar kind, but more familiar, in the dramatic writings of the Elizabethan age. The darker characteristics of the practice, however, are presented in the burning declamations of Juvenal, only too faithfully exhibiting the unnatural atrocities perpetrated in the form and under the disguise of love-potions and charms. Roman ladies in fact acquired considerable proficiency, worthy of a Borgia or Brinvilliers, in the art of poisoning and in the use of drugs. The reputed witch, both in ancient and modern times, very often belonged, like the Ovidian Dipsas, to the real and detestable class of panders: wrinkled hags were experienced in the arts of seduction, as well as in the employment of poison and drugs more familiar to the wealthier class (Sat. vi.). The great Satirist wrote in the latter half of the first century of Christianity; but even in the Augustan period such crimes were prevalent enough to make Ovid enumerate them among the universal evils introduced by the Iron age (Metamorphoses, i.). The despotic will of the princes themselves was exerted in vain; the mischief was too deep-rooted to succumb even to the decrees of the masters of the world. Nor did the divi themselves disdain to be initiated in the infernal or celestial science. Nigidius Figulus and the two Thrasylli are magical or mathematical names closely connected with the destinies of the two first imperial princes. Nigidius predicted, and perhaps promoted, the future elevation of Octavianus; and the elder Thrasyllus, the famous Rhodian astrologer, skilfully identified his fate with the life of his credulous dupe but tyrannical pupil. Thrasyllus' art is stated to have been of service in preventing the superstitious tyrant from executing several intended victims of his hatred or caprice, by making their safety the condition of his existence. The historian of the early empire tells of the incantations which could 'affect the mind and increase the disease' of Germanicus, Tiberius' nephew. 'There were discovered,' says Tacitus, 'dug up from the ground and out of the walls of the house, the remains of human corpses, charms and spells, and the name of Germanicus inscribed on leaden tablets, ashes half consumed covered with decaying matter, and other practices by which it is believed that souls are devoted to the deities of hell.'26
In the fourth century, the first Christian emperor limited the lawful exercise of magic to the beneficial use of preserving or restoring the fruits of the earth or the health of the human body, while the practice of the noxious charms is capitally punished. The science of those, proclaims the imperial convert, who, immersed in the arts of magic, are detected either in attempts against the life and
