 Vesalius's success was due in large part to him exercising the skills of mindful dissections for the sake of understanding anatomy, much to the tune of Galen's "anatomy project" instead of focusing on the work of other scholars of the time in recovering the ancient texts of Hippocrates, Galen and others (which much of the medical community was focused around at the time).Vesalius was the first to publish a treatise, "De humani corporis fabrica", that challenged Galen "drawing for drawing".These drawings were a detailed series of explanations and vivid drawings of the anatomical parts of human bodies.
