According to Diogenes Laërtius, he was surnamed Tyrant of the Garden (Greek: Κηποτύραννος) from his exercising a kind of tyranny or supremacy in the garden or school of Epicurus.
[1] He was the teacher of Zeno of Sidon,[1] who succeeded him as the head of the school, about 100 BC.
He is said to have written upwards of 400 books,[1] but they have all been lost.
[2] The other was a Collection of Doctrines, in which he asserted that Epicurus had written a greater amount of original writing than the Stoic Chrysippus, because although Chrysippus had written 700 books, they were filled with quotations from other authors.
