LOL. Exactly. The Patroclus/Achilles slash craze came a few centuries after the Iliad was written. So, Plato's time. Fifth century Athenians elites were a bunch of creepy fujioshis, gaying up all their great-grandpa's old stories just like the friggen Sherlock fandom today. You read the actual Iliad, and Achilles throws a hissy fit and sits out half of the book because Agamemnon steals his captive bedwarmer, and Patroclus' bit of war booty cries over his body after he dies like, 'He was the nicest rapist a girl could ever ask for.' The Iliad is only about a narrow conflict within the greater Trojan war. The war has already been going on when the poem starts, and it isn't close to done when the poem ends. It is the epic tale of the fallout of one man's cockblocking.
People forget that ancient cultures existed and evolved for centuries. It's hard to make accurate blanket statements like, "Ancient Greeks did this/believed that. Or Romans, or Egyptians." Even their 'stories' changed over time, it would be like asking a random British kid from every decade the story of Robin Hood, and having it change depending on if they grew up with Errol Flynn or Disney gateway furs. Ancient Greece got progressively more obsessed with teh big geh, sliding into the Hellenistic period, where Alexander the Great and his boyfriend went to Troy and laid flowers at Achilies and Patroclus' going, "OMG they were so like us amirite!?"
All this to say, Lyndsay, If you're gonna cite a myth in your video essay, give the specific version you're citing. The date and presumed provenance plz.
