Illustration of the Ancient Greek philosopher and naturalist Aristotle (384-322 BC). Aristotle influenced many later thinkers, working in areas such as logic, astronomy, zoology, embryology and physics. He grew up in Macedon, and then, from the age of 18, spent nearly 20 years at Plato's Academy in Athens. Engraving, based on an antique sculpture in the Spada Gallery, Rome, from Vies des Savants Illustres (1866).
