Mythology easter egg 2 [pjo]
Polyphemus almost marrying Grover might seem random at first. You wouldn't be blamed if assumed that Rick did that cuz satyrs and goats, and he raises sheeps, but there's also more precedent than that
It's a reference to a small comedy theater piece, Cyclops, by Euripides, very Adam Sandler type of humor. Where Polyphemus tries to, er, marry a satyr named Silenus. In this version, tough, he is aware he is satyr, and that he is a man, even comparing Silenus to Ganimedes.
The whole thing very much reads like Odyssey's fanfic (aren't those popular nowdays?), if a bunch of satyrs somehow got on board with Odysseu's crew. It might have something to do with the very obscure reference that quots Penelope as Pan's mother, but I'll not be the one uraveling that one
