The Mansi collection of the museum consists of 36 objects that were part of a single complex of a shrine. This complex is represented by seven wooden idols and tablets depicting the sun and the moon. The museum expedition, working in the north of Western Siberia, discovered the place of worship in 1939. It was described in detail by the Omsk local historian Andrei Fyodorovich Palashenkov.

The idols of the shrine (kapishche) were discovered near the village of Saranpaul in the Ostyak-Vogul National District of Omsk region (modern Khanty-Mansi Autonomous Okrug–Yugra). They were placed on the bank of a stream flowing from the left side into the Lyapin River (a tributary of the Northern Sosva), 2–2.5 kilometers down the river from Saranpaul. The figures were made at the end of the 19th century.

“Sat menkv” (or “seven menkvs”) are anthropomorphic images of patron spirits. They were used in religious rites by the Sosva Mansi. The sacred place was located in the forest near a stream in a clearing. The basis of the shrine were two thick, slightly sloping larch trees, which stood not far from each other. A long thick pole was tied to them with strips of cloth at the level of 60 centimeters from the ground. Seven idols were placed there slightly tilted to the right. The leftmost one was particularly slanted, with the tilt gradually decreasing from idol to idol.

The center of the group was occupied by the largest idol, which was 138 centimeters long. The idols to the right and left of it were progressively smaller towards the edges. The length of the smallest one was 81 centimeters. The idols were made of cedar trunk mainly using an ax, and a knife for finer details.

The central idol symbolized the father of the family. His whole body was wrapped in a man’s jacket sewn on a machine from black cloth. Behind the collar of its clothes and in its pockets sacrificial offerings were found — 15 copper coins with the date of issue from 1818 to 1931 and 9 silver coins, issued between 1923 and 1932, in denominations up to 15 kopecks. Other idols also had coins and 15-kopeck postage stamps.
