Lit. Remarks on Old Paintings, a 51 chapter, mid-19th century, painters' biography compiled by Asaoka Okisada 朝岡興禎 (1800-56), son of Kano Naganobu 狩野栄信 (1775-1828). Biographies for roughly 3,500 painters from the Asuka to the early Edo periods are included in 48 chapters. Specific arrangement is based on the social rank of the artist within a general chronological order. About 480 Chinese emigrant painters living in Nagasaki as well as Korean painters are also included. For each artist, reference is made to characteristic examples of their work, and their signatures are faithfully copied. There are also extensive appendices which list technical terms as well as paintings on sliding doors *fusuma 襖, folding screens *byōbu 屏風, and handscrolls *emaki 絵巻. An inscription in Chapter 50 gives a date of 1845 (Kōka 弘化 2), while another in Chapter 1 is dated 1850 (Kaei 嘉永 3). The original manuscript is preserved in the Library of Tokyo Geijutsu Daigaku 東京芸術大学. In 1904 Ōta Kin 太田謹 revised and published a supplemented edition, Zōtei koga bikō 増訂古画備考, primarily adding information suggested by Meiji scholars.
