A Ken is a Buddhist ritual sword, particularly prevalent within the Shingon school of Buddhism in Japan. The blade of this particular ken, composed of 12th century japanese steel, was then remounted on a Vedic symbolic object known as a vajra or ‘thunderbolt’ originating from the Indian subcontinent and whose gods were integrated into the shingon pantheon around the 9th century. This specific vajra, which is used as the hilt, dates to the 14th century. A vajra-hilted ken may be called an e-ken, a syncretic rendering of the sword-of-wisdom that is connected to the Vedic-Buddhist king of light Fudō Myō-ō. As a composite item of two different periods and places, this Ken demonstrates not only the physical movement of the Silk Roads, but the enduring nature of the Silk Roads, that they can move objects over several centuries that likewise have religious associations geographically distant from one another. The materials used in the construction and decoration of these objects reveal the wealth of the societies they come from, as evidenced by the presence of metals such as copper, gold, and steel.
This steel blade measures 12.0625 inches and features two rivet holes along the tang, dating to either the late Heian period or the Early Kamakura period in Japan (late 12th century to early 13th century). The ken functions as a Buddhist ritual sword that symbolizes enlightenment and triumph over evil. Its quality demonstrates advanced metalworking by this period, even for ritual weapons, though the exact techniques used are unclear. The vajra itself dates to the mid 14th century in Japan during the Nambokuchō period. It is constructed primarily of copper with gilded decoration, which is most prevalent in a frontal bead and the habaki, the piece that secures the blade to the hilt. Three prongs protrude on the pomel, two prongs protrude from the blade side, with the middle prong being the slot for the blade itself. 1
The sword components here have been rendered into ritual symbols, at least in the case of the hilt. While this had been depicted in art, the physical recreation as a bladed weapon ties together the planes of religious and martial acculturation. This can be compared to other instances along the Silk Road of religious iconography being rendered as a weapon used for ritual purposes rather than battlefield struggle. Mixed metallurgy utilizing a precious metal like gold implies the components were made in a wealthy societal context.
