in fabulous history, a son of Neptune and Amyone, king of Euboea. He was the father of the famous Palamedes, who was so unjustly sacrificed to the artifice and resentment of Ulysses by the Greeks at the Trojan war. The death of Palamedes highly enraged Nauplius; and to revenge the injustice of the Grecian princes, he endeavoured to debauch their wives, and ruin their characters. When the Greeks returned from the Trojan war, Nauplius was pleased to see them distressed in a storm on the coasts of Euboea; and to make their disaster still more universal, he lighted fires on such places as were surrounded with the most dangerous rocks, that the fleet might be shipwrecked upon the coast. This had the desired effect; but Nauplius was so disappointed when he saw Ulysses and Diomedes escape from the general distress, that he threw himself into the sea. According to some mythologists there were two persons of this name: one a native of Argos, who went to Colchis with Jason. He was son of Neptune and Amyone.—The other was king of Euboea, and lived about the time of the Trojan war. He was, as some observe, son of Clytonas, one of the descendants of Nauplius the Argonaut. The Argonaut was remarkable for his knowledge of sea affairs and of astronomy. He built the town of Nauplia, and sold Auge daughter of Aleus to King Teuthras, to screen her from her father's resentment.
