Archedemus of Tarsus in Wikipedia

Archedemus (Greek: Άρχέδημος) of Tarsus,[1] a Stoic philosopher who flourished c. 140 BC. Two of his works: On the Voice (Greek: Περὶ Φωνῆς) and On Elements (Greek: Περὶ Στοιχείων), are mentioned by Diogenes Laertius.[2] He is probably the same person as the Archedemus, whom Plutarch calls an Athenian, and who, he states, went into Parthia and founded a school of Stoic philosophers at Babylon.[3] Archedemus is also mentioned by Cicero,[4] Seneca,[5] and other ancient writers.
