Antipater of Tyre in Wikipedia

Antipater (Greek: Ἀντίπατρος; 1st century BC) of Tyre was a Stoic philosopher, and a contemporary of Cato the Younger and Cicero.[1] Antipater is said to have befriended Cato when the latter was a young man.[2] He appears to be the same as the Antipater of Tyre mentioned by Strabo.[3] He lived after, or was at least younger than, Panaetius. Cicero,[4] in speaking of him, says, that he died "recently at Athens", which must mean shortly before 45 BC. From this passage we can infer that Antipater wrote a work On Duties (Latin: de Officiis), and Diogenes Laertius [5] refers to a work by him On the Cosmos (Greek: περὶ κόσμου): The whole world is a living being, endowed with soul and reason, and having aether for its ruling principle: so says Antipater of Tyre in the eighth book of his treatise On the Cosmos. -Diogenes Laertius, vii. 139
