Who came up with the idea for the Trojan horse?

spartans

well of course not! Sparta refused to take part in the Trojan war! A young man named Odysseus made up the plan! He came, I believe, from Athens, but I am not quite sure... Sorry! But he had to be close to Athens...

In the film Troy, King Odysseus came up with the idea to create the Trojan horse while he was sitting in a camp-fire by the shores of Sparta the night after the fight between Achilles and Hector was fought. Odysseus saw one of his soldiers carving a small horse, the soldier told Odysseus that he was carving it as A GIFT for his son!
