The oldest written prescriptions we have are Sumerian, on clay tablets from around 3000 BCE, listing plant and mineral preparations. Babylonian medicine distinguished the asu, a practical healer working with drugs and dressings, from the ashipu, who dealt with the spiritual causes of illness. The Diagnostic Handbook attributed to Esagil-kin-apli, around 1050 BCE, organises symptoms into a systematic list — recognisably the ancestor of clinical description.
Egyptian medicine was unusually practical. The Ebers Papyrus of about 1550 BCE contains over seven hundred remedies. The Edwin Smith Papyrus is a surgical text that describes forty-eight injury cases in a consistent format — examination, diagnosis, treatment, prognosis — and in several instances frankly concludes that the injury cannot be treated. That intellectual honesty is striking three and a half thousand years later.
Egyptians used honey on wounds, which we now know is genuinely antibacterial; willow for pain, which contains the precursor of aspirin; and castor oil, still in use. They also prescribed a good deal that did nothing, and some things that were poisonous.
Imhotep, architect and physician of the Third Dynasty, was later worshipped as a deity of healing — perhaps the first physician in history known by name.
The decisive shift came with Hippocrates of Kos in the fifth century BCE. The Hippocratic writings argue that disease has natural causes rather than divine ones, that the physician should observe closely and record carefully, and that the body has its own tendency to heal — vis medicatrix naturae. The Hippocratic Oath established that medicine carries obligations.
Their explanatory theory was the four humours: blood, phlegm, yellow bile and black bile, with health as their balance. The theory was wrong. But its underlying idea — that illness is imbalance rather than possession — runs parallel to tridosha in India and yin-yang in China, and it changed what medicine was for.
Alongside this ran the temple medicine of Asklepios, where the sick slept in the sanctuary hoping for a healing dream. Rational and religious medicine coexisted comfortably for centuries.
Rome contributed public health more than theory: aqueducts, drains, baths, military hospitals. Dioscorides, a Greek army physician, compiled De Materia Medica around 65 CE, describing roughly six hundred plants; it remained the standard reference for fifteen hundred years.
Galen, physician to gladiators and then to emperors, systematised humoral theory so thoroughly that his authority went essentially unchallenged into the seventeenth century. He was a brilliant anatomist working mainly on animals, which meant some of his errors were carried faithfully for over a thousand years — a useful reminder of what happens when a system stops being questioned.
