Alexandria Medical School

Following the conquests of Alexander the Great (356-323 BC) and the formation of new kingdoms by his successors, the center of Greek learning and medicine shifted from Athens and the Greek Islands to Alexandria in Egypt.

A famous medical school was established in old Alexandria during the third century BC. The Alexandria medical school introduced the notion that the level of understanding was dependent upon the detail of the observation.

The medical school was dominated by the ‘empirical’ outlook represented by Serapion of Alexandria (220 BC).

Anatomy was particularly advanced due to the possibility of dissecting the human body. Among the doctors attracted to work at Alexandria two were outstanding - Herophilus of Chalcedon and Erasistratus of Ceos.

Herophilus of Chalcedon

Herophilus, the Elder, moved to Alexandria after initial training under Praxagoras. His greatest contributions to medical research were largely in anatomy and he conducted important investigations, based at times on human dissection, into the brain and nervous system, the vascular system, the liver, the eye and the reproductive organs.

Many graduates of this medical school traveled and practiced throughout the Mediterranean basin. Galen (131-210 AD), born of Greek parents in the region that is now Turkey, was influenced by the teachings of Alexandria and Greek schools of thought. He later moved to Rome where he developed a considerable following, Galen wrote over five hundred medical treatises of which over one hundred have survived into modern times.

The medical school of Alexandria was still active until late in the 3rd century AD. However, it slipped slowly into oblivion after the fire of 389 AD, which also devastated its famous library.

Aristotle and the end of Athens

Aristotle and the end of Athens
Aristotle (384-322 BC) followed closely after Hippocrates and although not himself a physician, had a profound effect on medical thought and practice for succeeding centuries.

Indeed he can regarded as one of the greatest scientific geniuses the world has ever seen. Aristotle was the son of a physician, and a pupil of Plato; later he became tutor to the young Alexander the Great.

Although Aristotle never dissected a human being, he carried out anatomical studies of a wide range of animals, laid the foundation of embryology by studying the developing chick, and gave an accurate account of the life of bees.

He laid the basis of the doctrine of evolution, describe a ladder of nature ascending through lower plants, higher plants, insects, fish, mammals to man.

Soon after the deaths of Hippocrates and Aristotle. The great days of Athens drew to an end. The Macedonian, Alexander the Great the pupil of Aristotle conquered Greece, Asia Minor and Egypt, marched through Persia and reached India.

In his progress he founded a string of at least 17 Alexandria but it was Alexandria of Egypt that was by far the most important.

After the death of Alexander, one of his generals, Ptolemy declared himself Pharaoh, took up residence in Alexandria and there founded a great medical school and library at about 300 BC; into these institutions were imported scientist, mainly from Greece.

Unfortunately the vast library said to have contained some 700 000 manuscripts, was burned by a mob of fanatics intent on destroying the past, a phenomenon not unknown in later periods of history.

We have to rely, therefore on the writings of Galen and other authors to learn something of the Alexandria school of medicine.

Of particular fame were two surgeons, Herophilos and Erasistratos, both of whom flourished around 300 BC.

Their most important contribution was systematic dissection of human bodies; indeed, Celsus states that they actually performed vivisections on condemned criminals.

Herophilus named the duodenum and prostate and established the brain as the center of consciousness; his name survives in one of the venous sinuses of the brain.

Erasistratos is regarded by some as the founder of physiology; he distinguished the cerebrum from the cerebellum, noted the difference between sensory and motor nerves, and gave a good description of the heart valves.

With the absorption of Egypt into Roman Empire in 50 BC and with death of Cleopatra in 30 BC, marking the end of the Ptolemaic dynasty, Alexandria ceased to have medical influence and Rome became of central importance.
