Gikeiki
The , "The Chronicle of Yoshitsune", is a Japanese gunki monogatari ("war-tale") that focuses on the legends of Minamoto no Yoshitsune and his followers. Thought to have been written during the Nanboku-chō period, it has provided inspiration to numerous Noh, kabuki and bunraku plays. Much of the image that people today have of Yoshitsune and those associated with him ( Saitō no Musashibō Benkei and Shizuka Gozen, for example) is considered to have been influenced by the Gikeiki.
The word "Gikeiki" literally means "The Record of Yoshitsune", but the on-yomi of the kanji for his name are used in reading it aloud – "yoshi" is read as "gi", and "tsune" is read "kei".
