Ulysses is one of the Greek leaders, a wily and sneaky man who easily manipulates those around him.
He is the cleverest of the Greeks, and hence the most dangerous. He prefers thinking and tactics to blunt force, which makes some other fighters look down on him. Excellent at gathering information and therefore aware of almost everything that’s going on, he knows exactly what strings to play to make others come around to his point of view, whether in discussing Achilles’s and Patroclus’s mockery of the Greek leadership or praising Nestor’s wisdom. He comes up with the plot to goad Achilles into returning to the fighting and carries it out, directing the others in their parts. He neither likes nor trusts women, and immediately takes Cressida for no more than a whore. Never one to miss a chance to find out more, he agrees to help Troilus find Cressida in the Greek camp, where his opinion of her is not improved. With Diomedes, Ulysses was one of the Greeks who went to Troy to require Helen’s return and was refused, leading to the war. He will later come up with the idea of the Trojan Horse and bring the war to an end.
