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.
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.
