During the classical period in Athens, the Macedonians, to the north, were considered barbarians, most likely because their dialect seemed foreign to the Greeks of the south.
In other words the term barbarian did not actually mean uncivilized but not-understandable though to us it brings to mind people gnawing on raw meat or the skulls of their enemies. This is not what it meant to the ancient Athenians thiough one could of course argue that they saw everyone who was not Athenian or spoke any language besides Greek as being a second tier civilzation. (Some people say the Greeks still feel this way). The Macedonians admired the southern Greeks and King Phillip
hired the philosopher Aristotle to tutor his young son Alexander. Aristotle was actually a 'barbarian import', having been born in Macedonia and raised in the royal court, his father being the royal doctor. Alexander, according to Plutarch was actually the son of Phillip's Queen, Olympias, and Zeus on one of his earthly visits.
In the 4th Century King Phillip of Macedonia took advantage of the disunity of the Greek city states, defeating an Athens that was paralyzed by political infighting, in the battle of Chaeronia in 338 BC. and put an end to the Delian league. He then unified all the Greeks to the south of his kingdom in Pella.
When Phillip was assassinated in 336, the 20 year old Alexander became the new king of Macedonia. He immediately ordered the execution
of all of his potential rivals and marched south with his armies in a campaign to solidify control of Greece. He continued to unite the rest of the Greeks in Asia Minor and traveled east where he conquered Greece's great enemy Persia, as well as the lands of Egypt and as far as India. By then he was known as Alexander the Great and this
era became known as the Hellenistic Age, when the influence of Greece spread throughout the known world. To this day there are pockets of people between the Mediterranean and India who claim to be descendents of Greeks in Alexander's army. Besides bringing Hellenism to the people of the east he brought eastern ideas to the people of Greece. When Alexander died of a mysterious illness in Babylon on June 10, 323 BC, he was only 32 years old. The lands he had conquered were divided up and named for his three
generals: the Ptolemids in Egypt, the Antigonids in Greece and Macedonia and the Seleucids in Syria, Asia Minor and the Middle East. (See map)
During the Hellenistic period and on into the Roman period Athens was what a University town is today. Still a beacon of learning, Plato's Acadamy and Aristotle's Lykeion were expanding and attracting more and more students. The art of Rhetoric had become essential for polititians of the Greek world who came to Athens to study in the school of Isokrates, a rival of Plato. The schools sent a flow of educated students out into the world who themselves became teachers of
own people, as well as scientists, mathematitions, philosophers, and political and military leaders. After Plato died in 347 B.C, Aristotle left Athens and moved to Assos (nowadays called Behramkale), in Asia Minor. Assos was a city by the sea, 10 km from Lesbos. There, with the help of other philosophers (including Theophrastos and Xenokrates) he founded a philosophy school, under the protection of Hermeias, the ruler of Assos and Atarneos. Aristotle soon married Pythias, who was Hermeias niece,
and they moved to Mytilene, in Lesvos, where they lived for two or three years. Most historians of science agree that it was during this period that Aristotle began his intensive study of zoology, which is described in his books "History of animals", "Parts of animals", "Generation of animals"
and a few others. In those books Aristotles describes many fish, birds, insects and land animals that he found in Lesvos, and several specific places of this island are mentioned in those works. In 343 or 342 B.C. Aristotle and Pythias moved to Pella (the ancient capital of Macedon) at the invitation of king Phillip II, to take care of the education of prince Alexander. Although Aristotle's zoological work is not as well
known as his logical and philosophical books, it was
a vast encyclopaedia of natural history and was surpassed only in the 18th century. There is a famous saying by Darwin, who was much impressed the first time he read Aristotle's zoological books: "I had not the most remote notion what a wonderful man he was. Linnaeus and Cuvier have been my two gods, though in very different ways, but they were mere schoolboys to old Aristotle."
