I find it odd he missed it, since it’s kind of a big deal in ancient Greek culture. In Ovid’s Metamorphoses, his book of moral myths, he told the story of Baucis and Philemon, an old, poor couple from the town of Phrygia, who were the only folks to take in a pair of strangers. When Baucis noticed her jar of wine wasn’t getting any emptier, she realized the strangers were gods: Zeus and Hermes, actually. (And when Barnabas and Paul visited Lystra and healed someone, the Lystrans freaked out and assumed they were Zeus and Hermes,
Or Jesus.
