Biography Aristoteles
Aristotle was born in 384 a.c. in the city of Stagira (why is nicknamed Aristotle), not far from the actual Mount Athos in Chalkidiki peninsula, then part of the Kingdom of Macedonia (today Macedonia). His father, Nicomachus, was physician to King Amyntas III of Macedonia, which explains his relationship with the royal court of Macedonia, which would have an important influence in his life.

In 367 a. BC, when Aristotle was 17, his father died and his tutor Proxenus of Atarneus sent him to Athens, then an important intellectual center of the Greek world to study at Plato's Academy. There he remained for twenty years.

After Plato's death in 347 a.c., Aristotle left Athens and traveled to Atarneus and Aso, in Asia Minor, where he lived for about three years under the protection of his friend and former fellow of the Academy, Hermias, who was governor of the city.

When was killed Hermias, Aristotle traveled to the city of Mytilene, on the island of Lesbos, where he remained for two years. There he continued his research by Theophrastus, a native of Lesbos, focusing on zoology and marine biology. Also married Pythias, the niece of Hermias, with whom he had a daughter the same name.

In 343 a.c., King Philip II of Macedonia invited Aristotle was tutor to his son of 13, who would later be known as Alexander the Great. Aristotle then traveled to Pella, then the capital of the Macedonian empire, and Alejandro taught for at least two years until he started his military career.

In 335 a.c., Aristotle returned to Athens and founded his own school, the Lyceum (named for being located within an enclosure dedicated to the god Apollo Licio). Unlike the Academy, the Lyceum was not a private school and many of the classes were public and free. Throughout his life Aristotle collected a vast library and a number of followers and researchers, known as the Peripatetic (from περιπατητικός, 'itinerant', named after the custom of discussing walking). Most of the works of Aristotle are preserved from this period.

When Alexander died in 323 a.c., Athens is likely an uncomfortable place for the Macedonians, especially for those with connections Aristotle returned. After declaring (by all accounts) that he saw no reason to let Athens sin twice against philosophy (referring to the condemnation of Socrates), Aristotle left the city and went to Chalcis in Euboea, where he died a year next, at 322 a.c., of natural causes.
