He joined the Greeks in the expedition against Troy. He is also credited with several inventions: Pausanias in his "Description of Greece" (2.20.3) says that in Corinth there is a Temple of Fortune to which Palamedes dedicated the dice that he had invented; Plato in "The Republic" (Book 7) remarks (through the character of Socrates) that Palamedes claimed to have invented numbers; and others note him in connection with the alphabet.
