According to Nicander, the most pestiferous asp is about an ell in length, its colour squalid, its eyes of a drowsy appearance, and when it bites a person it leaves a very small wound; neither swelling nor inflammation is perceived, “and the man without pain sinks into a profound sleep.” This is the serpent which Cleopatra despatched herself with. See some curious remarks upon this event, and the nature of the serpent in Galen (Ther. ad Pison.), from which our author borrows his account of it. Nicander says of the cerastes that it resembles the male viper, only that the latter has no horns, whereas the former has either two or four. Isidorus says of them, “_Aspis_ vocata quod morsu venena immittat et aspergat: ἱὸς enim Græci venenum dicunt, et inde _aspis_ quod morsu venenato interimat” (Orig. xii, iv); and of the cerastes, “_Cerastes_ serpens dictus eo quod in capite cornua habeat similia arietum: sunt autem quadrigemina cornicula, quorum ostentatione, veluti escâ illiciens sollicitata animalia perimit.” (Ibid.) Harris says, “The shephephon (Gen. xlix. 17) is probably the cerastes, a serpent of the viper kind.” (Nat. Hist. of the Bible.) Bochart, however, has proved that the shephephon signifies both the cerastes and the hæmorrhus, which are very much alike, being both vipers. (Hier. ii, 416.) Sprengel, in fact, makes the hæmorrhus to be the same as the cerastes. Our author’s treatment is principally taken from Dioscorides. Aëtius, however, gives the fullest account of them. He says the sting of the most fatal species of asp proves fatal in three hours; and that those wounded by the cerastes generally live nine days. He represents the asp as occasioning great coldness, torpor, and at last convulsions. Besides the local remedies applicable in all such cases, he recommends in an especial manner vinegar, which is to be administered in great quantities. Celsus thus explains the way in which vinegar proves efficacious for counteracting the effect of a frigorific poison: “Credo quoniam id (acetum) quamvis refrigerandi vim habet, tamen habet etiam dissipandi. Quo fit ut terra respersa eo spumat. Eadem ergo vi verisimile est spissescentem quoque intus humorem hominis ab eo discuti, et sic dari sanitatem.” The author of the work ‘Euporistôn,’ usually published with those of Dioscorides, recommends, in the case of a person stung by the asp, constant shaking, beating, and movement of the whole body, with the affusion of hot salt water. (Euporist. ii, 120.) Pliny says the poison of an asp proves immediately fatal when introduced into a fresh wound, more slowly when the sore is old, and that it is perfectly innoxious when swallowed by the mouth. (N. H. xxix, 18.) The account which Avicenna gives of these serpents is mostly taken from Aëtius and our author.
