Timeline
The history of medicine does not move in a straight line. It advances through borrowed texts, epidemic shocks, new instruments, changing institutions, and repeated arguments about who deserves care and who gets to define disease.
Antiquity
Egyptian medical papyri, Hippocratic writings, and Galenic theory helped establish durable habits of explanation: observation, regimen, prognosis, and the belief that bodily balance could be described systematically.

Medical knowledge circulated across Byzantine, Islamic, Jewish, and Latin Christian settings. Translation movements, hospitals, commentaries, and urban plague responses reshaped how inherited learning was preserved and used.

Print culture, anatomy theatres, global trade, military medicine, and colonial exchange altered the scale of medical argument. New remedies and new violence travelled together.
