The Stoics

A shipwrecked merchant, a boxer, an emperor, a slave. The people who built Stoicism led lives as instructive as their books — meet each of them, and follow the ones whose works survive into the Library.

The Early Stoa

c. 300–150 BC

Stoicism began on a painted porch — the Stoa Poikile — in the Athenian marketplace. The first three heads of the school built the whole system: its logic, its physics, its ethics. Their books are lost; their ideas survived everything.

Zeno of Citium
c. 334–262 BC
The merchant who lost everything and founded a school
Cleanthes
c. 330–230 BC
The boxer who hauled water by night to study by day
Chrysippus
c. 279–206 BC
The runner who wrote the system down — 705 books, none survive

The Middle Stoa

c. 150–50 BC

The school crossed the sea. Two Greeks from the eastern Aegean carried Stoicism into the Roman world and reshaped it for people with careers, families, and public duties — philosophy for the imperfect, not just the ideal sage.

The Roman Stoa

c. 50 BC – AD 180

A senator, a statesman, an exiled teacher, a former slave, an emperor. Every complete Stoic work that survives was written in this period — this is the Stoicism you can read in the Library.
