This note offers a new suggestion on the meaning of the name of Er. After showing in detail why the solutions offered in the literature so far are not satisfying, I argue that we should “hear” the name of Er, which only appears in Plato’s text in the genitive form Ἠρός, as a pun with the typically Homeric word ἥρως that describes a “courageous soldier” (as Er is presented), especially Odysseus, whom Er/Ἠρός is meant to replace in this Platonic Nekuia.
