Centuries ago, botanical drawings were key to helping people keep records of plants that had healing properties. The incredibly detailed illustrations of herbs and other plants were designed so that botanists and doctors could recognize the species for medicinal purposes. The oldest surviving example of botanical art, the Codex Vindebonensis, dates back to 512 A.D. The illustrations became more detailed and accurate as the centuries unfolded and now have taken on an artistic rather than medical purpose. There has been a recent resurgence in the art form through groups such as the American Society of Botanical Artists.
