Posidonius is a Latinized form of the Poseidonios name, ultimately derived from the Greek god Poseidon, meaning "of Poseidon." The name was borne by a prominent 1st-century BC Stoic philosopher, Posidonius of Apameia (c. 135–51 BC), who was a Greek native of Apamea in Syria. He was renowned as a polymath—an astronomer, geographer, historian, mathematician, and teacher—and is considered the most learned man of his time, possibly of the entire Stoic school.
Etymology
The name Posidonius is derived from the Greek Poseidṓnios, which means "of Poseidon." This connects to the root Poseidon, the name of the Greek god of the sea. The god's name itself may be composed of Greek πόσις (posis) meaning "husband" or "lord" and δᾶ (da) meaning "earth." The name first appears in Mycenaean Greek inscriptions as po-se-da-o. In Greek mythology, Poseidon was the unruly god of the sea and earthquakes, brother of Zeus, often depicted with a trident and riding a chariot drawn by white horses.
Historical Bearers
Posidonius (Ancient Greek: Ποσειδώνιος) "of Apameia" or "of Rhodes" (c. 135–c. 51 BC) was a Greek politician, astronomer, astrologer, geographer, historian, mathematician, and teacher. After studying Stoic philosophy under Panaetius in Athens, he traveled extensively through Spain, Africa, Italy, Gaul, Liguria, Sicily, and the eastern Adriatic. He later settled as a teacher at Rhodes, where his reputation attracted many scholars, including Cicero and Pompey. His works are now lost, but they influenced later Stoic thought and geography, providing information on many topics.
