Archedemus of Tarsus in Wikipedia
Archedemus (Greek: Άρχέδημος) of Tarsus, 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.
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.
Archedemus is also mentioned by Cicero, Seneca, and other ancient writers.
