Is there an instance in which a Greek (or related, Roman, Trojan...) would bow to a god if they appeared? I would think not.
Iliad
Athena appears to Achilles, did not bow.
Athena appears to Odysseus, did not bow (runs to the ships).
Ares.. appears to Diomedes, did not bow (they fought).
Apollo appears to Diomedes, did not bow (tried to fight the god).
Aphrodite appears to Helen, did not bow (sat on bed crying and angered the goddess).
Odyssey
Hermes to Odysseus did not bow (sat on the beach crying).
Athena to Odysseus did not bow (gets angry with the goddess).
Athena (in the guise of a friend) to Telemachus (and the 100+ suitors and company), did not bow (does not really count because Telemachus didn't know he was a goddess).
Aeneid
- Venus to Aeneas did not bow (don't play with me like that mother).
But, in all these instances, the mortal was a favorite of the god/goddess. So, I am looking for an instance in which a mortal lowers themselves as a sign of respect for a god/goddess. Does one exist?
