Iron tsuba of round form decorated with dragonfly (tombo) and comma (comma-like swirl, tomoe) in openwork (sukashi) outlined with brass wire. The plate decorated with 5 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: Diameter: 89.5 mm, thickness: 3.1 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13].   Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."

Tomoe (Comma): The character 巴 (Chinese pronunciation bā). A pattern resembling the two-comma tomoe (futatsu-domoe) has been found in ancient cultures on all inhabited continents. ...aside from their military function, a ritual or fetish value, perhaps related to their testicular shape. It also has yin-yang connotation. The gold sekigane confirms the high value of the piece to the owner.
