Matthias de L'Obel, who had studied medicine…
1584 CE
Matthias de L'Obel, who had studied medicine in Leuven and at the University of Montpelier with Guillaume Rondolet before becoming physician to William the Silent, had argued in his Stirpium adversaria nova, written in 1570 in collaboration with Pierre Pena, that botany and medicine must be based on thorough, exact observation.
A collection of data about some twelve hundred plants that L'Obel had observed and gathered, the work is an attempt to classify plants into families according to the form of their leaves (L'Obel's rough notions of genus and family will later be developed by Carolus Linnaeus; a few of L'Obel's plant groups are still recognized.)
Plantarum seu stirpium historia, 2 vol. (1576), comprises the second edition of the Stirpium adversaria, together with the Stirpium observationes, an appendix with 1,486 engravings by botanists such as Pietro Mattioli, Rembert Dodoens, and Charles de l'Ecluse.
Having lived in the Low Countries from 1571, L’Obel leaves in 1584 for England.
