Plutarch, Timoleon

34. After this, Timoleon made an expedition against Mamercus to Catana, conquered and routed him in a pitched battle near the stream of the Abolus, and slew above two thousand of his soldiers, a large part of whom were the Carthaginians sent him as auxiliaries by Gisco. Thereupon the Carthaginians made a peace with him which they sought themselves; the terms were that they should keep the territory within the river Lycus, restoring their families and property to all who wished to change their homes from there to Syracuse, and renouncing their alliance with the tyrants. [2] Then Mamercus, despairing of success, took ship for Italy with the purpose of bringing the Lucanians against Timoleon and Syracuse; but his companions on the voyage turned their triremes back, sailed to Sicily, and handed Catana over to Timoleon, whereupon Mamercus himself also was compelled to seek refuge in Messana with Hippo the tyrant of that city. [3] But Timoleon came up against them and besieged them by land and sea, and Hippo was caught as he was trying to steal away on board a ship. Then the Messanians took him into the theatre, brought their children thither from their schools to behold, as a glorious spectacle, the tyrant's punishment, and put him to torment and death. As for Mamercus, he gave himself up to Timoleon on condition that he should undergo trial at Syracuse, and that Timoleon should not denounce him. [4] So he was brought to Syracuse, and when he came before the people, attempted to rehearse a speech composed by him a long time before; but being received with noise and clamour, and seeing that the assembly was inexorable, he flung away his mantle, ran right across the theatre, and dashed head foremost against one of the stone steps, hoping to kill himself. However, he was not so fortunate as to die in this way, but was taken away, still living, and crucified like a robber.
