Note 503 — Chapter V · THE DEMONOLOGY OF GHOSTS AND SPRITES AND BOGEYS.
Reading edition
Aesch. Prom. Vinct. 800 ἃς θνητὸς οὐδεὶς εἰσιδὼν ἕξει πνοάς. The line is usually rendered ‘no mortal may behold them and live,’ but, in the light of the account of Athenaeus, it is clear that the πνοαί are the intolerable exhalations, not the breath of life.
