Zeno of Citium

Zeno came from Citium on Cyprus around 334 BC, a merchant's son in a Phoenician port city. After losing his cargo in a shipwreck and washing up in Athens, he wandered into a bookseller's stall, read about Socrates, and asked where to find such men; the bookseller pointed him toward the Cynic philosopher Crates. Zeno studied under the Cynics, absorbed their contempt for convention and their focus on virtue, then softened the edges and systematized the vision. Around 300 BC he began teaching at the Stoa Poikile, the painted colonnade in the Athenian agora, and his students took their name from the place. His school preached that virtue alone mattered, that one should live in harmony with nature's rational order, and that peace of mind came from accepting what you couldn't control. Stoicism spread through the Hellenistic kingdoms, became the working philosophy of Roman emperors, and has been revived twice since - once in the Renaissance, once now.
