Jaeger, W. W. Nemesios von Emesa : Quellenforschungen zum Neuplatonismus und seinen Anfängen bei Poseidonios, 1914
Wikipedia 24 September 2022: (Posidonius (Greek: Ποσειδώνιος Poseidṓnios, "of Poseidon") "of Apameia" (ὁ Ἀπαμεύς) or "of Rhodes" (ὁ Ῥόδιος) (c. 135 – c. 51 BC), was a Greek politician, astronomer, astrologer, geographer, historian, mathematician, and teacher native to Apamea, Syria. He was considered the most learned man of his time and, possibly, of the entire Stoic school. After years of study and travel, he settled as a teacher at Rhodes. Next to Panaetius, he did most, by writings and personal lectures, to spread Stoicism to the Roman world. His works are now lost, but they proved a mine of information to later writers. The titles and subjects of more than twenty of them are known. https://en.wikipedia.org/wiki/Posidonius
