[Footnote 098: Venomous exudation.--Ver. 8. This was the substance called 'hippomanes,' which was said to flow from mares when in a prurient state. Hesiod says, that 'hippomanes' was a herb which produced madness in the horses that ate of it. Pliny, in his Eighth Book, says that it is a poisonous excrescence of the size of a fig, and of a black colour, which grows on the head of the mare, and which the foal at its birth is in the habit of biting off, which, if it neglects to do, it is not allowed by its mother to suck. This fictitious substance was said to be especially used in philtres.] [Footnote 099: Moon was empurpled.--Ver. 12. If such a thing as a fog ever exists in Italy, he may very possibly have seen the moon of a deep red colour.] [Footnote 101: That she, transformed.--Ver. 13. 'Versam,' 'transformed,' seems here to be a preferable reading to 'vivam,' 'alive.' Burmann, however, thinks that the 'striges' were the ghosts of dead sorcerers and wizards, and that the Poet means here, that Dipsas had the power of transforming herself into a 'strix' even while living, and that consequently 'vivam' is the proper reading. The 'strix' was a fabulous bird of the owl kind, which was said to suck the blood of children in the cradle.

The pupil, or apple of the eye, is that part through which light is conveyed to the optic nerve. Some persons, especially females, were said by the ancients to have a double pupil, which constituted what was called 'the evil eye.' Pliny the Elder says, in his Seventh Book, that 'all women injure by their glances, who have a double pupil.' The grammarian, Haephestion, tells us, in his Fifth Book, that the wife of Candaulcs, king of Lydia, had a double pupil. Heinsius suggests, that this was possibly the case with the Ialysian Telchines, mentioned in the Seventh Book of the Metamorphoses, 1. 365, 'whose eyes corrupting all things by the very looking upon them, Jupiter, utterly hating, thrust them beneath the waves of his brother.'] [Footnote 103: And their grandsires.--Ver. 17. One hypercritical Commentator here makes this remark: 'As though it were any more difficult to summon forth from the tomb those who have long been dead, than those who are iust deceased.' He forgot that Ovid had to make up his line, and that 'antiquis proavos atavosque' made three good feet, and two-thirds of another.] [Footnote 105: The twofold doors.--Ver. 20. The doors used by the ancients were mostly bivalve, or folding doors.] [Footnote 106: Mars in opposition.--Ver. 29. She is dabbling here in astrology, and the adverse and favourable aspects of the stars. We are to suppose that she is the agent of the young man who has seen the damsel, and she is telling her that the rising star of Venus is about to bring her good luck.]
