Revolutionary anatomy.................................

"For more than 1,300 years, all Western professional knowledge about human anatomy has stemmed from the teachings of the Greek physician Galen (AD 129-216), and most physicians were never required to study the inside of the human body.  So when Flemish physician and anatomist Andreas Vesalius (1514-64) suddenly focused his attention on dissecting human corpses and describing what he found in meticulous detail, both his approach and its results shook up the medical field.  Many considered it profane."
