Mochus (Greek: Μωχός) the Phoenician is listed, along with Zalmoxis the Thracian and Atlas the Libyan, by Diogenes Laërtius as a proto-philosopher. Athenaeus claimed that he authored a work on the history of Phoenicia. Strabo, on the authority of Posidonius, speaks of one Mochus or Moschus of Sidon as the author of the atomic theory and says that he was more ancient than the Trojan war. He is also referred to by Josephus, Tatian, and Eusebius.
