Pietro Andrea Mattioli

Pietro Andrea Gregorio Mattioli (Matthiolus) (23 March 1501-1577) was a doctor and naturalist born in Siena.

He received his MD at the University of Padua in 1523, and subsequently practiced the profession in Siena, Rome, Trento and Gorizia, becoming personal doctor of Ferdinand and Maximilian II.

A careful student of botany, he described 100 new plants and coordinated the medical botany of his time in his Discorsi ("Commentaries") on the Materia Medica of Dioscorides. The first edition of Mattioli's work appeared in 1544 in Latin. There were several later editions in Latin, and translations into Italian, French, and German.



In addition to identifying the plants originally described by Dioscorides, Mattioli added descriptions of some plants not in Dioscorides and not of any known medical use, thus marking a transition from to the study of plants as a field of medicine to a study of interest in its own right. In addition, the woodcuts in Mattioli's work were of a high standard, allowing recognition of the plant even when the text was obscure.
