ATHENODORUS, surnamed CANANITES or SANDONUS, a Stoic philosopher, was born at Tarsus, and went to the court of Augustus, who made him tutor to Tiberius. Augustus esteemed him greatly, having proved by experience his virtue and probity. He used to speak very freely to the emperor, and warned him, whenever he found himself giving way to anger, to rehearse the twenty-four letters of the alphabet before he resolved to say or do anything. He died at the age of 82. None of his works have survived. There was another Stoic of this name, surnamed Cordylion, also of Tarsus, who was keeper of the library at Pergamus, and died at Rome in the house of Cato the Younger. There were likewise two sculptors named Athenodorus, one of whom assisted Agesander in the group of the Laocoön.
