THERSITES. That same Diomed’s a false-hearted rogue, a most unjust knave; I will no more trust him when he leers than I will a serpent when he hisses. He will spend his mouth and promise, like Brabbler the hound; but when he performs, astronomers foretell it: it is prodigious, there will come some change; the sun borrows of the moon when Diomed keeps his word. I will rather leave to see Hector than not to dog him. They say he keeps a Trojan drab, and uses the traitor Calchas’ tent. I’ll after. Nothing but lechery! All incontinent varlets!
