Claudius Galenus (born 131 A.D.) saw two patients and introduced two ideas: first, that diabetes is a weakness of the kidneys, which can not hold back water and also are thirsty for fluid; second, that the urine consists of the unchanged drink. Galen's great authority maintained these errors for about 1500 years, and retarded progress in the knowl edge of diabetes.
