This predominant cultural view of Musashi is somewhat contradicted by old texts such as Dobo goen (1720), which relay his intimacy with the courtesan Kumoi in his middle age.[2] The Bushu Denraiki details Musashi fathering a daughter by a courtesan. The daughter is said to have died young which caused him great grief. It is uncertain if this courtesan and Kumoi were the same person.[citation needed] A rumour also connected Musashi with the oiran Yoshino Tayu.[3]
