Palamedes, however, was more than a match in artifice for the Ithacan king. Taking Telemachus from the arms of his nurse, he placed the infant on the sand in front of the plowing team. Ulysses quickly turned the animals aside to avoid injuring his child, thus proving that he was not mad but in full possession of his senses. The king of Ithaca was therefore obliged to join the expedition to Troy. With twelve ships well manned he sailed from his rugged island, which he did not again see for twenty years. Ten years he spent at the siege, and ten on his homeward voyage, during which he met with the wonderful adventures that Homer describes in the Odyssey. Ulysses had his revenge upon Palamedes in a manner very unworthy of a brave man. In the camp before Troy, during the siege, he bribed one of the servants of Palamedes to conceal a sum of money in his master's tent. He then forged a letter, which he read before a council of the Greek generals, saying that Palamedes had taken it from a Trojan prisoner. This letter was written as if by King Priam to Palamedes, thanking him for the information he had given regarding the plans of the Greeks, and mentioning money as having been sent him in reward for his services. The Greek generals at once ordered a search to be made in the tent of Palamedes, and the money being found where it had been hidden by direction of Ulysses, the unfortunate Palamedes was immediately put to death as a traitor. Palamedes, not unknown to fame, Who suffered from the malice of the times, Accused and sentenced for pretended crimes. VERGIL. It is said that Palamedes was the inventor of weights and measures, and of the games of chess and backgammon, and that it was he who first placed sentinels round a camp and gave them a watchword. There was another of the Greek princes whose help in the Trojan War was obtained only by an ingenious trick. This was the famous A-chilʹles. He was the son of Peleus and Thetis, at whose marriage feast Eris threw the apple of discord on the table. The prophecy that Thetis would have a son greater than his father was fulfilled in Achilles, the bravest of the Greeks at the Trojan War, and the principal hero of Homer's Iliad. Thetis educated her son with great care. She had him instructed in all the accomplishments fitting for princes of those times. When he was an infant she dipped him in the river Styx, which, it was believed, made it impossible for any weapon wielded by mortal hands to wound him. But the water did not touch the child's heel by which his mother held him when she plunged him in the river, and it was in this part that he received the wound of which he died.
