Museum of Anthropology and Ethnography bought an album of watercolor paintings in 1947, in the Leningrad branch of the Akademkniga store for 800 rubles. The name of the author and the time of creation of the drawings were indicated on the first page: “A. Pomerantsev. 1851”. Unfortunately, the name of A. Pomerantsev is absent in reference books devoted to graduates of the Academy of Arts and the history of Russian fine arts. Watercolor portraits of the Kazakh and Kyrgyz nobility, which are contained in the album, suggested that A. Pomerantsev was a contemporary of the famous Kazakh humanist scientist Chokan Valikhanov. The mention of the artist Pomerantsev is found in a more detailed study of biographical information about Valikhanov. The educated society of Omsk paid attention to the artistic talent of A. Pomerantsev, he was ordered portraits and paintings. He was a colonel of the General Staff, a very educated man who passionately loved art, which was of particular importance for the development of the artistic abilities of the young Ch. Valikhanov. A. Pomerantsev taught painting in 1847–1853 in the Cadet Corps of Omsk, the period of study of C. Valikhanov. Three watercolor portraits from A. Pomerantsev's album “The Wild-Stone Horde Manap Baynazar Turumtaev”, “The Wild-Stone Horde Biy Sartai (Ambassador 1849)” and “The Great Horde, Sultan Mamyr Khan Rustemov” coincide even in detail with pencil drawings his student C. Valikhanov. Later, possibly under the influence of Valikhanov, with whom he was connected by friendship, A. Pomerantsev became interested in Kazakh ethnography, began studying folk dwellings and published a series of articles on this topic. Album “A. Pomerantsev. 1851” is one of the earliest collection materials of the museum on the Kazakhs and Kyrgyz. Watercolors of the artist can be considered one of the first visual sources on the history of clothing, they feature in details folk costumes, decorations from the mid-19th century. A. Pomerantsev was one of the first professional artists interested in the study of the Kazakh and Kyrgyz national costume and did a lot for the development of the domestic fine arts.
