[763] ἰνίον: the great tendon at the back of the neck supporting the head (“τοῦ τριχωτοῦ κρανίου … τὸ θ̓πίσθιον [ἐστὶν] ἰνίον,” Arist. H.A. 1. 7. 2), near the medulla oblongata, the chief centre of sensation. We often read of blows dealt there, e.g. Theocr. 25. 264, “αὐχένος ἀρρήκτοιο παρ᾽ ἰνίον ἔφλασα προφθάς.” For the physical particularization, which mars for us the beauty of the passage, cf. Cat. 64. 377, with Ellis' note.
