In the meantime, another former Pythagorean, who was born here, in Croton, is doing natural philosophy with a medical bent. Dissecting human corpses is forbidden for religious reasons, but his studies on animal eyes and brains, have led him to the conclusion that it's the brain, rather than the heart, that is the seat of mind and emotions. Similarly to the Pythagoreans, Alcmeon views the world as a constant struggle of opposites. This includes the human body, where ''warmth'' competes against ''coldness'', ''moistness'' against ''dryness'', and so forth. A balance between them all is what keep you in good health, while the predominance of any one characteristics leads to illness.
'''Hippocrates of Kos''', born about half a century after Alcmeon, will eventually combine the latter's theory with Empedocles's by assigning one humour (including the imaginary black bile) to each of the four elements in order to explain the struggles of ''hot'' vs ''cold'' and ''moist'' vs ''dry''. He will be also introduce known for introducing the general rule that the physician's duty is to make the patient feel better or at least not worse, ; and develop for contributing so much to medical theory to the point were that it becomes a standalone scholarly discipline. And all this without ever peeking inside a human body. This opportunity will only be available in the following century (4th BCE) to doctors working in Alexandria, such as '''Herophilus of Chalcedon''' and '''Erasistratus of Ceos'''. This they will owe to the first Greek rulers of Egypt, of the house of Ptolemy, who, for the benefit of science, will allow dissections of human corpses to take place on the premises of the Alexandrian temple of the muses, (known as a "museum", but in fact really more akin to like a university).
Much later, under the Roman Empire (1st–2nd centuries CE), Greek medics working in what will once be Turkey, will once again be only allowed to dissect animals (leading, for example, to a long-held notion that the human liver has not two, but five lobes, like in a dog) and will only ever have the chance to study human anatomy while looking after wounded soldiers and gladiators. What '''Dioscorides of Anazarbus''' and '''Galen of Pergamon''' will be remembered for is summarising all medical knowledge in books that will be read by generations of medics for centuries after the works of their predecessors will have gone up in smoke together with the library of the Alexandrian museum. Galen's book, in particular, will be crucial for preserving the theory of humours, which will come to be known as Galenic theory.

Like much of the achievements of the Greco-Roman civilisation, Galenic medicine will be largely forgotten after the fall of the western part of the Roman Empire, but will survive in its Byzantine part, from where it will be gleaned by the Arabs and from them, by the Persians. A man who will make the greatest contributions to further develop the theory will live in 11th-century Uzbekistan under the name Abu Ali al-Husayn ibn Abdillah ibn al-Hasan ibn Ali ibn Sina (but known as or '''Avicenna''' in Europefor short). In the following century, the medical knowledge preserved and expanded by the Muslims, will filter back into western Europe thanks to, among others, '''Constantine the African''', who will bring it from Tunesia to Salerno, Italy. It's in Salerno where Europe's first medical school will be located and where Greek medical text texts will be translated from Arabic and Hebrew, the chief languages of medicine. This is how Galen, along with "his" humoral theory, will be rediscovered in Europe and popularised in courtly circles by such courts physicians as '''Michele Savonarola''' (his better-known grandson, Girolamo, will study medicine too, but then he's going to quit the studies and get busy with religion and politics). Finally, in the 1470s, Bartolomeo Sacchi (better known as '''Platina''') will publish the first ever printed cookbook, ''De honesta voluptate et valetudine'' (''Of Honest Pleasure and Good Health''), which will introduce wider European populace with recipes marrying the pleasure of eating and humoral medicine.

W XVI w.In the 16th century, już po odkryciach after the discoveries made by da GamyGama, Kolumba i innych podróżnikówColumbus and others, Europejczycy zaczną wreszcie zdawać sobie sprawę, że jeśli antyczne autorytety myliły się w sprawach geograficznychEuropeans will finally realize that if ancient authorities got it wrong about geography, then it's possible they also got it wrong about other things. It will be the time of the first medics to może w innych też nie należy im ślepo wierzyć. Pojawią się wtedy pierwsi lekarze kwestionujący teorię Galenowskąquestion Galenic theory, z Philippusem Aureolusem Theophrastusem Bombastusem with Philippus Aureolus Theophrastus Bombastus von Hohenheimem Hohenheim (zwanym też skrótowo or '''ParacelsusemParecelsus'''for short) na czeleat the helm. Ale dwa lata po jego śmierciTwo years after his death, czyli w 1525 r.though, all works of Galen will be finally published in print, w Wenecji zostaną w końcu wydane drukiem dzieła wszystkie Galena w greckim oryginalein the Greek original, co spowoduje wysyp nowych przekładów i ponowny renesans galenizmuleading to new translations and a renewed interestest in Galenism. Kiedy w połowie XVII w. nastąpi wreszcie nasycenie rynku wydawniczego poradnikami medycznoBy mid-17th century, with European book market finally saturated with humoral medical-dietetycznymi propagującymi teorię humoralnądietary handbooks, Galen's authority will have been thrown into doubt once again, autorytet Galena będzie już mocno nadszarpnięty dalszymi odkryciami Andriesa following the discoveries of the likes of Andries van Wesela Wesel (or '''WesaliuszaVesalius''', który wykaże, iż who will prove Galen myli się w opisie budowy sercawrong about the structure of human heart), '''Williama HarveyaWilliam Harvey''' (który odkryje, że żyły i tętnice tworzą obieg zamkniętywho will discover that veins and arteries form a closed circuit) i and '''Jana Baptista Jan Baptist van HelmontaHelmont''' (który udowodni, że za trawienie nie odpowiada „wewnętrzne ciepło”, ale kwasy żołądkowewho will show that digestion is due to gastric acids and not to an "inner heat"). Co nie znaczy, że dietetyka humoralna zniknie zupełnieBut all that is not say that humoral dietetics will have been completely forgotten.
