This article lists the main interpretations of figures in long robes (so-called “boots”) engraved on the planes of the Oshkolskaya Pisanitsa and other neighboring rock carvings of Northern Khakassia. S.V. Pankova’s arguments in favor of their interpretation as Manichaean or Nestorian priests and attribution to the time of Tashtyk culture are considered. The author presents alternative interpretation and dating of figures in long robes. A Chinese painting of the XIII century “Nomads”, depicting two women in boqtag – traditional headdress of Mongol nobles, is proposed as an iconographic close analogy to Khakas rock art “boots”. The author suggests that the Chinese medieval scroll “Nomads” depicts a Mongolian wedding procession and rock engravings of figures in long robes in Khakassia reflected matrimonial contacts of Yenisei Kyrgyz leadership with Mongol nobles.
