Years before we had cameras, people relied on artists and their work to capture the world around them. This resulted in a tradition of exquisite botanical illustrations, in which painters and draftspeople painstakingly rendered every detail that they saw into two-dimensional form. The book Fungi Collected in Shropshire and Other Neighbourhoods is an example of this art form. Created in the 19th century by a woman author, it faithfully follows her archival journey of England and Wales's numerous fungi species—traveling much further than the title initially suggests.
The project itself is divided into three dense volumes. Lewis—whom we know very little about—spent over 40 years (from 1860 to 1902) wandering her country and sketching the mushrooms that she came across. It should come as no surprise that she ended up with hundreds of illustrations from her efforts, all made with pencil and filled in with delicate layers of watercolor. Sometimes, just two drawings are placed on a page, while other spreads feature several fungi that have been collaged together. Accompanying each piece is a hand-written note of what species it is.
Despite the incredible efforts that went into this book, it appears as though it was a self-initiated project which Lewis worked on across her lifetime. The only known volumes are hand-drawn and hand-bound, suggesting they were the only copies made. Even so, historians believe that Lewis likely had some formal training in decorative illustration, most likely in an unrelated field, and then applied her passion for plant life and science to her carefully crafted books.
