Galen

c. 129 CEc. 216 CE · Pergamon

Galen of Pergamon (129-c. 216 CE) was a Greek physician, surgeon, and philosopher who became the most influential medical writer of antiquity, serving as doctor to the emperor Marcus Aurelius and his successors at Rome. His vast body of writing on anatomy, physiology, and medical theory, much of it built on the doctrine of the four humors, dominated medicine in the Byzantine, Islamic, and European traditions for over a thousand years. He is among the most prolific authors of the ancient world.

  • The doctor who ruled medicine for 1,300 years was alive in Rav's youth

    Galen — court physician to the Roman emperor, and the doctor whose writings would dominate European and Islamic medicine for over a thousand years — was still alive while Rav (Abba Arikha), founder of the great academy at Sura, was a young man. The father of Babylonian Talmud study and antiquity's most influential physician overlapped by about four decades.

    How we know

    Galen c. 129–216 CE; Rav (Abba Arikha) c. 175–247 CE. Overlap 175–216 ≈ 41 years; Rav founded Sura c. 220 CE.

  • Galen proved arteries carry blood, not air — about 1,450 years before circulation was understood

    Against the prevailing view that the arteries were full of air or a life-spirit, Galen showed by experiment around 180 CE — tying off a living artery in two places and cutting between the ligatures — that arteries in fact carry blood. A full account of how the blood actually circulates would not come until William Harvey in 1628 CE, roughly 1,450 years later.

    How we know

    Galen c. 129–216 CE; double-ligature demonstration c. 180 CE, overturning the older pneuma/air doctrine; William Harvey, De Motu Cordis, 1628 CE. Gap = 1,628 − 180 = 1,448 ≈ 1,450 yrs.

What they did here

Born in Pergamon (Mysia) c.129 CE, son of the wealthy architect Aelius Nicon, who oversaw his early education; Galen reports this in his own writings (e.g. De ordine librorum suorum).

About Pergamon

Pergamon was a major Greek city in Mysia, northwestern Asia Minor, near modern Bergama, Turkey; it was the capital of the Attalid kingdom and famous for its library. The physician Galen was born and trained there before his career at Rome. In late antiquity Pergamon was also the seat of a Neoplatonist school, among whose students was Eusebius of Myndus.
