The National Museum of Korea is going to put on display original manuscripts of the first Buddhist text written in the Korean alphabet Hangeul.
This is the "Seokbosangjeol," written in the 1400s during the reign of King Sejong of the Joseon Dynasty.
Part of the collection, donated by the late former Chairman of Samsung Group, Lee Kun-hee volumes 20 and 21 will be unveiled for the first time on Thursday in line with Hangeul Day next month.
They are different from the volume 11 already on display which is a woodblock print version.
A total of 24 volumes are believed to have been published.
Prince Suyang, the son of Sejong, commissioned the manuscripts after the death of his mother, Queen Soheon.
The museum will also put on display 152 metal types believed to be from the 15th century.
