Noblemen Portraits of Dong-A University consists of a total of 5 pieces: <portrait of confucius>, <portrait of juja>, <portrait of gija>, <portrait of <a href="/entity/m01nl3p" data-gacategory="annotation" data-gaaction="clicked" data-galabel="assetpage_injected_link_v1">Zhuge Liang>, and <portrait of song si-yeol>. On the top left and right of all portrait screens, there is a writing in the same font, and in particular, on the back of the portrait of the Gija, ‘Eunjinhu Songraeheeheegeunseo’ is written, so it turns out that all of them were written by Song Naehee (1791-1867). Song Si-yeol's descendant, Song Nae-hee, is believed to have enshrined a portrait in the Song Si-yeol-affiliated neo-Confucian Academies, hoping that noblemen will continue to be worshiped. This collection of portraits of noblemen is a rare case that can be observed in one place. It is also a valuable relic because it shows an aspect of Neo-Confucian culture in the 19th century.
As a result of conducting a preliminary investigation before preservation treatment, all 5 points showed severe horizontal bending, and damage such as peeling of pigments and ink books and floating screens had progressed. In particular, in <portrait of confucius>, even the flowers and paper were lost due to insect damage. . The pigment was analyzed as a mixture of mineral colored pigments such as white (light white), red (cinnabar + dye), blue (stone blue), yellow (light white + dye), and black (light white + ink) and dyes dissolved in water.
The most important part of the preservation treatment was the processing method of the overlapping backing paper of <portrait of a gija> and <portrait of a juja> and the degree of color matching of the defective part. At the expert advisory meeting, it was decided to cut the paper for both portraits as thin as possible without removing them. In addition, it was decided to alleviate the stains on the <portrait of confucius> as much as possible.
