A poor man, Aktis attended Kleon's talk of restoring Athens' glory. Because of this, he and his friends, among them Pratinos, were drawn into a plot to murder a statesman and a friend of Perikles, Metiochos.
Together with the others, Aktis procured venomous snakes from a man living outside the city walls. Aktis was bitten by accident, and died from the snake's poison. The others left his body behind the house where they kept the snakes, until they assaulted Metiochos at his home, tied him up, and left him in the middle of the snakes.
