Authentic Greek stamp celebrating Medicine, specifically Rheumatology. This is an ancient Greek image of a doctor, possibly Hippocrates, trying to remove the bad “humors” that flowed through a patient’s body and were thought to cause Rheumatic diseases. The removal of the bad humors was by venipuncture as depicted in this image. The patient has arthritis and is using a crutch. This is an authentic Greek stamp and has a postmark on it.
