『菅家須磨記』の成立と流布についての試論

Kanke-suma-no-ki is a writing dealing with travels which depicts how Sugawara Michizane, who had been left for Dazaifu, departed Kyoto for Suma. It was formerly believed to be written by Michizane himself. However, since Motoori Norinaga asserted that it was a forgery, it has been considered that the book was written only after the Edo period. In fact, the true author and the precise date cannot be determined.

In this paper, I considered the appearance and the author of Kanke-suma-no-ki through the examination of the postscripts in the various handwritten copies. As a result, it can be deduced that Kanke-suma-no-ki was written by the Kanazawa lord Maeda Tsunanori (1643-1724). I pointed out that the book was found after his death in Kanazawa and then brought to Tsuboi Yoshichika (1657-1735), a scholar in Kyoto, and that the volume, transcribed and revised by Yoshichika, was further transcribed by his students and acquaintances to become known in the world.
