Fabriciusor Fabrizio Girolamo

Fabricius, or Fabrizio, Girolamo, called "Aquapendente" from his birthplace, was born in 1537, and became a famous professor of anatomy in the university of Padua, where Harvey was his pupil. His discovery of the valves of the veins led to the latter's theory of the circulation of the blood. He died in 1619.

“God is a skilful physician. He knows what is best. God observes the several tempers of men, and knows what will work most effectually. Some are of a more sweet disposition, and are drawn by mercy: others are more rugged and knotty pieces: these God deals with in a more forcible way. Some things are kept in sugar, some in brine. God doth not deal alike with all, he hath trials for the strong, and cordials for the weak.”
–Thomas Watson, A Divine Cordial
