Diodorus of Alexandria was a pupil of the philosopher in what tradition?
Posidonius Posidonius (Greek: Ποσειδώνιος, "Poseidonios", meaning "of Poseidon") "of Apameia" (ὁ Ἀπαμεύς) or "of Rhodes" (ὁ Ῥόδιος) (c. 135 BCE – c. 51 BCE), was a Greek Stoic philosopher, politician, astronomer, geographer, historian and teacher native to Apamea, Syria.
Potamo of Alexandria Potamo (or Potamon) of Alexandria (Greek: Ποτάμων ὁ Ἀλεξανδρεύς ) was an eclectic philosopher who lived in the Roman era. According to Diogenes Laërtius, Potamo had "not long ago" created an eclectic sect of philosophy, which would mean that he lived sometime around the 2nd century CE. However, the Suda says that Potamo lived in the age of Augustus (late 1st century BC) which, if true, would mean that Laërtius probably copied a statement, without alteration, from an earlier writer.
