3000-2500 BC). The first phrases of the Smith papyrus (ca. 1600 BC) demonstrated that ancient Egyptians directly associated the pulse with the heart: “The counting of anything with the fingers (is done) to recognize the way the heart goes. There are vessels in it leading

to every part of the body. When a Sekhmet priest, any sinw selleckchem doctor… puts his fingers to the head to the two hands, to the place of the heart… it speaks in every vessel, every part of the body” 2,3 . In the Ebers medical Papyrus (ca. 1555 BC), the heart is again described as the centre of a system of vessels supplying the body. Going beyond underlining the importance of pulse examination, the text also alludes to cardiac rhythm disturbances and heart failure: “From the heart arise the vessels which go to the whole body… if the physician lay his finger on the head, on the neck, on the hand, on the epigastrium, on the arm or the leg, everywhere the motion of the heart touches him, coursing through the vessels to all the members…. When the heart is diseased, its work is imperfectly performed; the vessels proceeding from the heart become inactive so that you cannot feel them… If the heart trembles, has little power and sinks, the disease is advancing.” 2 The Egyptian cardiovascular medicine cannot be entirely

separated from spirituality and mysticism, as the heart played a pivotal role in the ancient Egyptian theology. However, the early Egyptian medicine, with its advanced clinical examination and diagnosis, paved the way to the scientific foundations of Greek and Roman medicine. Hippocrates and the four humours Hippocrates of Cos (460-377 BC) is recognized by most scientific historians as the Father of Medicine. He revolutionized the views of medicine and disease, mainly by recognizing that disease occurred naturally and

was not due to divine punishment. The Hippocratic Corpus is a collection of around seventy medical works from Alexandrian Greece. The Corpus was most probably not written by a single person, as it had different writing styles and variable subjects. It can be attributed, by consequence, to the “Hippocratic School”, a group of disciplines sharing similar views and methods 2 . In the Corpus, Hippocrates and his contemporaries theorized that health is a state of balanced humours while disease was a Brefeldin_A state of imbalanced humours. These humours are blood, black bile, yellow bile, and phlegm. The four humours correspond to the four elements of nature (earth, wind, fire, and water) that reflect the four primary physical qualities (hot, cold, dry, and wet). Each humour was characterized by one of the four elements and a couple of the four qualities: blood, for instance, corresponded to the “fire” and was “hot” and “wet”. The behaviour and effects on the body of each humour was strictly related, by analogy, with these physical characteristics.
