Note 682 — EXCURSUS II. ON THE LINE ODYSS. V. 277.
Reading edition
I have observed that δεξιὸς ὄρνις means a bird flying from the left towards the right, and ἀριστερὸς ὄρνις, the reverse. Here however the force of the epithet is derived from immediate connection with the motion implied, and with the doctrine of omens: δεξιὸς ὦμος would of course be the right shoulder, and δεξιή, as we have seen, may stand alone to signify the right hand. And so in general with these words, when used as epithets, apart from a preposition implying motion, and from any relation to omens.
