Theophrastus (371 - 287 BC) was a student of Aristotle and is attributed with the title as the father of botany. Theophrastus wrote books on botany such Enquiry into Plants and On the Causes of Plants. In these books, he worked to categorize plants into the groups, study their uses and how to grow them and took note on the anatomy of plants. Based on Theophrastus work we can see how early botanical study revolved around the idea of the usefulness of the plant and trying to create basic distinctions between different plant types. Bartolomeo Confalonieri was the first to print Theophrastus's books in 1483 while in Treviso which allowed much of Europe to learn about his findings. Though it is not known for sure, Theophrastus writing would have been available prior to Leonardo's observations of plants and could have been read by the artist.
