Who was Posidonius?

Posidonius of Apamea in Syria studied Stoicism with Panaetius in Athens and then travelled for years through Spain, Africa, Italy and Gaul doing research. He settled as a teacher on Rhodes, where Pompey and Cicero came to know him, and after Panaetius he did the most to bring Stoicism to Rome.

He was considered the most learned man of his age. He tried to measure the distance and size of the Sun and the diameter of the Earth and to explain the Moon's effect on the tides. Like other Stoics of his time he also drew on Plato and Aristotle. His works are lost, but later writers relied on them heavily.
