Francis Barrett, Lives of alchemystical philosophers (1888)
“ In the year 1557, at Bois le Duc, in Brabant, John Baptist van Helmont was born of a noble family. He studied at Louvain, and became eminent in mathematics, algebra, the doctrines of Aristotle and Galen, and the medicine of Vopiscus and Plempius. At seventeen he lectured on physics as prælector, and took his degree of medical doctor in 1599. He read Hippocrates and the Greek and Arabian authors before he was twenty-two years old. He then passed ten years in the unsuccessful practice of physic, until he met a Paracelsian chemist, who discovered various chemical medicines to him. ”
