It is not a little curious to remark the operation of the antagonist principles of superstition and scepticism among the Romans in this enlightened period, as it comes illustrated to us in the compositions of Horace on this subject. In the piece, the contents of which have just been given, things are painted in all the solemnity and terror which is characteristic of the darkest ages. But, a few pages further on, we find the poet in a mock Palinodia deprecating the vengeance of the sorceress, who, he says, has already sufficiently punished him by turning through her charms his flaxen hair to hoary white, and overwhelming him by day and night with ceaseless anxieties. He feels himself through her powerful magic tortured, like Hercules in the envenomed shirt of Nessus, or as if he were cast down into the flames of Aetna; nor does he hope that she will cease compounding a thousand deadly ingredients against him, till his very ashes shall have been scattered by the resistless winds. He offers therefore to expiate his offence at her pleasure either by a sacrifice of an hundred oxen, or by a lying ode, in which her chastity and spotless manners shall be applauded to the skies. What Ovid gives is only a new version of the charms and philtres of Medea. [114] ERICHTHO. Lucan, in his Pharsalia, [115] takes occasion, immediately before the battle which was to decide the fate of the Roman world, to introduce Sextus, the younger son of Pompey, as impatient to enquire, even by the most sacrilegious means, into the important events which are immediately impending. He is encouraged in the attempt by the reflection, that the soil upon which they are now standing, Thessaly, had been notorious for ages as the noxious and unwholesome seat of sorcery and witchcraft. The poet therefore embraces this occasion to expatiate on the various modes in which this detested art was considered as displaying itself. And, however he may have been ambitious to seize this opportunity to display the wealth of his imagination, the whole does not fail to be curious, as an exhibition of the system of magical power so far as the matter in hand is concerned. The soil of Thessaly, says the poet, is in the utmost degree fertile in poisonous herbs, and her rocks confess the power of the sepulchral song of the magician. There a vegetation springs up of virtue to compel the Gods; and Colchis itself imports from Thessaly treasures of this sort which she cannot boast as her own. The chaunt of the Thessalian witch penetrates the furthest seat of the Gods, and contains words so powerful, that not the care of the skies, or of the revolving spheres, can avail as an excuse to the deities to decline its force. Babylon and Memphis yield to the superior might; and the Gods of foreign climes fly to fulfil the dread behests of the magician.
