ABSTRACT: The rational functions of primitive art are considered in the article. The reconstruction of the algorithm for the creation and use of petroglyphs as a marking of solar calendars and sundials with the help of an ancient astronomical instrument-gnomon is proposed. Standard geographic methods and observations of the shadow of objects were used in the study. To calculate the shadow charts, the basic trigonometric function and the astrocalculator were used. According to the results of the study, the following conclusions have been formulated: 1. The basis for constructing images is made up of graphic signs that reflect the movements of light; 2. The tool for marking the drawings could be a shadow of vertical objects and a rope; 3. To create the calendar, the most stable natural material-stone-was used, as well as noticeable elements of its heterogeneity-cracks and forms of relief.
