Portrait of Song si-yeol

It can be recognized as the portrait of Song Si-yeol because it is written on the top left, 'Portrait of Songja.' He is wearing a black Bok-geon on his head. The collar was worn in an overlapping manner such that the left collar was above the right collar, and the Daedae, a belt, was tied and hung under the sleeves. The belt was particularly expressed as being whiter, showing the difference in material. The portraits of Song Si-yeol is the most commonly remaining of single-person portraits, because Song Si-yeol was worshipped in Confucian shrines after the 18th century, and because the demand for his portraits increased in Seowon (lecture halls) and Yeongdang (shrines) as he was recognized as an oriental sage succeeding Zhu Xi.
