[330] ἐπιζαφελῶς, ‘furiously,’ Il.9. 516.We may refer “ἐπι-ζα-φελ-ῶς” to the root “φελ”, (seen in “ὀ-φέλλω”) = ‘swell.’ Thus the word is similar in use to Latin ‘tumidus,’ cp. Hom. Od.4. 3. 5; Virg. Aen.6. 407.The adjective “ἀφελής”, generally rendered ‘simple’ or ‘sincere,’ is really ‘not swollen’ and so ‘smooth.’ Others compound the word of “ἀ” priv. and “φελλεύς”, ‘rough ground.’ Athena did not now venture to vouchsafe her visible presence, but she throws off this reserve as soon as Odysseus has landed in Ithaca, and is beyond the power of Poseidon. It was the custom of the gods not openly to oppose each other, “θεοῖσι δ᾽ ὧδ᾽ ἔχει νόμος:”
“οὐδεὶς ἀπαντᾶν βούλεται προθυμίᾳ”“τῇ τοῦ θέλοντος, ἀλλ᾽ ἀφιστάμεσθ᾽ ἀεί” Eur. Hipp.1328.
