浅野長矩
In 1706, the great playwright Chikamatsu wrote a three-act puppet play entitled "Goban Taiheiki" ("A chronicle of great peace played on a chessboard"), placing the action in the era of "Taiheiki" (the 14th century); the third act appeared in another puppet play, and was ostensibly about the historical samurai Kō no Moronao; Moronao was actually a cipher for the offending master of court etiquette, Kira Yoshinaka, who was nearly slain by Asano Naganori. The use of Moronao's name for Kira and many of the other renamings would be copied in the later "Chūshingura".
