$Jinkoki$ and Publishers (The study of the history of mathematics 2018)

The first edition of Jinkoki 塵劫記 published in the 4^{th} year of Kan'ei 寛永4年, 1627, and it has a lot of riddles. The author thinks that YOSHIDA Mitsuyoshi (吉田光由 ) did not involve in this edition directly because the 1627 edition has no YOSHIDA's signature and seal of "Kao" 花押.In other hand, the 8^{th} and 11^{th} year of Kan'ei editions of Jinkoki, had them. Moreover the 4^{th} year of Kan'ei edition of Jinkokirevises them with black at the postscript. Originally there were publisher's names in that place. It is quite possible that YOSHIDA Mitsuyoshi had nothing to do with this publication and its publisher's name was hidden. The publication year of Jinkokiprinted by old wood block 古活字版, SUGITA's Jinkoki 杉田版塵劫記 and 5 volume edition of Jinkoki 五巻本塵劫記 are unknown yet, although they are old edition and are important. As medical doctor, SUGITA Ryoan Gen'yo 杉田良庵玄与 closely related to YOSHIDA Mitsuyoshi through MANASE 曲直瀬family. So SUGITA's Jinkoki is a matter of great importance. The edition the 9^{th} year of Kan'ei edition Jinkoki 寛永9年版塵劫記 in 1632, was published by the name of NAKANO Ichiuemon 中野市右衛門, which is similar with the 5 volume edition of Jinkoki similar publication. But NAKANO was famous publisher in Kyoto, it must be the false edition.
