Galen's understanding of anatomy and medicine was principally influenced by the then-current theory of the four humors: black bile, yellow bile, blood, and phlegm, as first advanced by the author of On the Nature of Man in the Hippocratic corpus. [11] Galen's views dominated and influenced Western medical science for more than
The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic. [ 2 ] [ 3 ] Most formulations include the possibility of mixtures among the types where an individual's personality types overlap and they share two or more temperaments.
Hippocrates' theory of four humors was linked with the popular theory of the four elements (earth, fire, water, and air) proposed by Empedocles, but this link was not proposed by Hippocrates or Galen, who referred primarily to bodily fluids. While Galen thought that humors were formed in the body, rather than ingested, he believed that ...
Galen's description of the body told through "pneuma" or what was understood to be the soul. The search for a hypothetical soul and its location have been a subject of much speculation throughout history. In early medicine and anatomy, the location of the soul was hypothesized to be located within the body.
Claudius Galen Guesses At It. Perhaps the most famous doctor to come out of the Roman empire, Claudius Galen acknowledges the clitoris and theorizes that “all the parts, then, that men have, women have too, the difference between them lying in only one thing, namely, that in women the parts are within, whereas in men they are outside.”
Balloonist theory was a theory in early neuroscience that attempted to explain muscle movement by asserting that muscles contract by inflating with air or fluid. The Roman and Greek physician Galen believed that muscles contracted due to a fluid flowing into them, and for 1500 years afterward, it was believed that nerves were hollow and that they carried fluid.

Andries van Wezel (31 December 1514 – 15 October 1564), latinised as Andreas Vesalius (/ v ɪ ˈ s eɪ l i ə s /), [2] [a] was an anatomist and physician who wrote De Humani Corporis Fabrica Libri Septem (On the fabric of the human body in seven books), which is considered one of the most influential books on human anatomy and a major advance over the long-dominant work of Galen.
Galen also made the mistake of assuming that the circulatory system was entirely open-ended. [16] Galen believed that all blood was absorbed by the body and had to be regenerated via the liver using food and water. [17] Galen viewed the cardiovascular system as a machine in which blood acts as fuel rather than a system that constantly ...
