Note 443 — Chapter V · THE DEMONOLOGY OF GHOSTS AND SPRITES AND BOGEYS.
Reading edition
As evidence of the evil reputation of Keres Mr Gilbert Murray calls my attention to the pun in Eur. Tro. 424 which seems to have escaped the attention of commentators:
τί ποτ’ ἔχουσι τοὔνομα; κήρυκες, ἓν ἀπέχθημα πάγκοινον βροτοῖς.
‘What name have they? A Kerish name.’ Hermes as κῆρυξ invokes and revokes κῆρες with his κηρυκεῖον, see pp. 26 and 43.
