Lykeio is an ancient Greek term that refers to a type of school or educational institution. It was often associated with the teachings of philosophers and was a place where students could learn various subjects, including philosophy, mathematics, and rhetoric. The most famous Lykeio was founded by the philosopher Aristotle in Athens around 335 BCE, where he taught and conducted research. The Lykeio served as a model for later educational systems, emphasizing the importance of critical thinking and inquiry. Students at the Lykeio engaged in discussions and debates, fostering a culture of intellectual exploration. This institution played a significant role in the development of Western education and philosophy.
