The watercolor illustration featured in this excerpt is a captivating glimpse into the pages of “Toshin seiyo” (The Essentials of Smallpox), a significant two-volume Japanese manuscript focusing on smallpox. Crafted by the skilled hands of the esteemed physician Kanda Gensen (c.1670-1746), this manuscript stands out for its detailed depictions of various symptoms associated with the disease. What sets this manuscript apart is the unique technique employed in its creation – each illustration was painstakingly painted on individual sheets of paper and then delicately assembled into the manuscript, adding a layer of intricacy to the work.

Moreover, the text of “Toshin seiyo” was meticulously refined by Enokimoto Gensho, another notable physician of that era. Gensho’s contributions not only helped to enhance the medical knowledge contained within the manuscript but also added a sense of depth and accuracy to the information presented. This collaborative effort between Kanda Gensen and Enokimoto Gensho highlights the dedication and commitment of these individuals to advancing the field of medicine through their combined expertise.

Kanda Gensen’s legacy extends far beyond “Toshin seiyo,” as he was a prominent figure renowned for his illustrated works on natural science and medical materials. His passion for both art and medicine shines through in his meticulous illustrations, which not only serve as educational tools but also as works of art in their own right. Through his groundbreaking contributions, Kanda Gensen left an indelible mark on the world of medicine and art, showcasing the profound impact that interdisciplinary collaboration can have in advancing knowledge and understanding.
