Zeno of Citium was a Greek philosopher who founded the STOIC school of philosophy. He was born in Citium, Cyprus in 334 BC and died in 262 BC. Zeno was one of the most influential figures in the development of Western philosophy. He is best known for his teachings on Stoicism, which emphasize the importance of living in accordance with nature and accepting life's hardships with equanimity. The term 'STOIC' is derived from Zeno's name and is used to describe someone who is indifferent to pleasure or pain, and who accepts life's events with composure.
