5. An officer in the service of Hannibal, of whom a story is told by Plutarch (Fab. Max. 15), that having accompanied his general to reconnoitre the enemy's army just before the battle of Cannae, Gisco expressed his astonishment at their numbers. To which Hannibal replied: "There is one thing yet more astonishing--that in all that number of men there is not one named Gisco."
