4th Century B.C.E:
Aristotle and Theophrastus got involved in identifying
plants and describing them.
Theophrastus was hailed as the “Father of botany”
because of his two surviving works on plant studies.
Although Aristotle also wrote about plants, he received
more recognition for his studies of animals.

who painted plants, attended classes on
