Ἡ ὕαινα, ὡς Ἀριστοτέλης λέγει, ἐν τῇ ἀριστερᾷ χειρὶ ἔχει δύναμιν ὑπνοποιόν, καὶ ἐνεργάζεται κάρον μόνον προσθιγοῦσα. πάρεισι γοῦν ἐς τὰ αὔλια πολλάκις, καὶ ὅταν ἐντύχῃ τινὶ καθεύδοντι, προσελθοῦσα ἡσυχῆ τὴν ὑπνοποιὸν ὡς ἂν εἴποις χεῖρα προσέθηκε τῇ ῥινί, ὁ δὲ ἄγχεταί τε καὶ πιέζεται. καὶ ἐκείνη μὲν ὑπορύττει τὴν γῆν τὴν ὑπὸ τῇ κεφαλῇ ἐς τοσοῦτον, ἐς ὅσον ἀνέκλασεν ἐς τὸν βόθρον καὶ τὴν φάρυγγα ὑπτίαν ἀπέφηνε καὶ γυμνήν· ἐνταῦθα δὲ ἡ ὕαινα ἐνέφυ καὶ ἀπέπνιξε καὶ ἐς τὸν φωλεὸν ἀπάγει.
(Aelian, Nat. Anim. 6.14)
The Hyena, according to Aristotle, has in its left paw the power of sending to sleep and can with a mere touch induce torpor. For instance, it often visits stables, and when it finds any creature asleep it creeps softly up and puts what you might call its sleep-inducing paw upon the creature’s nose, and it is suffocated and overpowered. Meantime the Hyena scoops out the earth beneath the head to such a depth as makes the head bend back into the hole, leaving the throat uppermost and exposed. Thereupon if fastens on to the animal, throttles it, and carries it off to its lair. (tr. Alwyn Faber Scholfield)
