Sambong chip
Sambong chip (삼봉집) is a collection of works by Chŏng Tojŏn, a key figure in the founding of Joseon and in the creation of Joseon's philosophy of government. It is a compilation of Chŏng Tojŏn (Sambong)'s poetry, prose, philosophy, and his plans for the reformation of the Goryeo /Joseon) government.
It was first published as two volumes by Chŏng Tojŏn's son, Chŏng Chin, in 1397. In 1465 it was republished and extended to six volumes by his great-grandson, Chŏng Munhyŏng, and later was further extended to eight volumes and republished under the same name in 1486.
The existing version of Sambong chip is that which was republished in 1791 by order of King Jeongjo, and includes writings omitted in the earlier versions, together with biographical information about Chŏng Tojŏn. This copy was designated a Treasure of the Republic of Korea (inventory number 1702 ) on 25 February 2011, while the woodblocks for this edition (held in the Bonghwa Chŏng clan's literature collection) were designated as Gyeonggi-do tangible cultural heritage item (no. 132) on May 7, 1986.
