# bio (long form, separated for readability)
bio: |
  Born around 135 BC in Apamea, Syria, Posidonius studied Stoic philosophy under Panaetius in Athens before spending years traveling Spain, Africa, Italy, Gaul, and the Adriatic coast for scientific research. He settled in Rhodes as a teacher, drawing scholars from across the Mediterranean and becoming known to Roman power brokers like Pompey and Cicero — key to pushing Stoicism into Roman intellectual life. He wrote more than twenty works blending Stoic doctrine with Plato and Aristotle, and pursued genuine questions in astronomy, geography, mathematics, and natural history: the size of the sun, the diameter of the earth, the moon's pull on the tides. All of it is gone now, surviving only as fragments and citations in the texts of those who came after.
