An Inner Case of a Book Made of Jade is a wooden container where a Books Made of Jade was stored. Because the container was encased in an additional container, it was named “Inner Case” according to the Royal Protocols. Unlike its Outer Case, an Inner Case was decorated with golden pigment over its lacquered body. During the Joseon Dynasty, Books Made of Jade and their cases were made at the same time for the installation of the queen and the royal ritual in which the king and the queen assumed honorific titles. After the king passed away, each of the cases of the Books Made of Jade that the king had been previously bestowed were loaded in a colored palanquin and enshrined in the Spirit-tablet Chamber of the Royal Ancestral Shrine during the Enshrinement Ceremony. Books Made of Jade functioned as the symbolic support for royal authority, since they record royal virtues.
