Fudō Myōō—literally, “the Immovable Wisdom King”—is a fearsome protector of Buddhist teachings. Originally an important deity of Japanese Esoteric Buddhism (Mikkyō), he was also revered in Zen temples. This triptych of images (1975.268.26–.28), hand-painted but with printed outlines, was created as one of the publication projects promoted by early medieval Zen temples to spread Buddhist teachings and iconography. This printed triptych seems to have been based on a painting of Fudō and his attendants executed by the noted Zen monk-scholar Ryūshū Shūtaku (also known as Myōtaku), who is said to have painted pictures of Fudō on a daily basis for over twenty years. The boy attendants often depicted with Fudō are Kongara (on the right) and Seitaka. The model for this printed triptych was most likely Myōtaku’s painting in the collection of the Henjōkō’in temple at Kōyasan
