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.

“The meanest and most contemptible person whom we behold is the offspring of heaven, one of the children of the Most High; and, however unworthily he may behave, so long as God hath not passed on him a final sentence, He will have us acknowledge him as one of His; and, as such, to embrace him with a sincere and cordial affection.”
–Henry Scougal, The Life of God in the Soul of Man
