Nearly all the ancient Greek physicians were authors of no mean calibre, considering the age in which they lived.

Pherecydes, a Greek philosopher and physician, wrote a book on diet during the sixth century before Christ. Pythagoras, his illustrious pupil, was said to be the first who dissected animals. He wrote, and taught anatomy and physiology, in the school of Crotona. Herodotus was a great teacher and writer; also Herophilus, his pupil. (B. C. 4th century.) There were four physicians named Hippocrates. The second of that name has nearly eclipsed all the others. The period in which he lived was highly favorable to the development of the qualities of the great Hippocrates. He was contemporary with Plato, Herodotus, who was his teacher, Pericles, Socrates, Thucydides, etc.

The most notable works of Hippocrates are 1st and 3d “Books on Epidemics,” “Prognostics,” “Treatise on Air and Water,” “Regime of Acute Diseases,” and “Treatise on Wounds.”

Heraclitus, of Ephesus, is conjectured to be the first who dissected the human body. “The principle of his theory is the recognition of the fire of life and the ethereal element of wisdom as the ground of all visible existence.” Fragments of his writings, only, have been preserved. He imitated Pythagoras.

Theophrastus wrote a book on plants. He lived to be one hundred and seven years old.

Herophilus first made diagnosis by the pulse, upon which he wrote a book.

Celsus was the author of eight works, yet Pliny makes no mention of him. Galen spoke of him as an excellent physician and writer; also Bostock.

Galen was a man of great talent and education. Suidas—11th century—says he wrote no less than five hundred books on medicine, and half as many on other subjects. His native tongue was Greek, but he also wrote in Latin and Persic.

Besides medicine, the above famous physicians wrote on philosophy, history, religion, etc. Poetry in those days was little more than heroic, or epic, prose.
