  The article presents the results of a study of petroglyphs on a unique stone
slab discovered near the kurgan 1 of the kurgan field Varvarinsky I (Rostov
Oblast, Russia). During the study was done comparing it with plates of Srubna
burials on which were depicted the petroglyphs. Similar features for all the
considered slabs are elliptically arranged wells. Groove made to Varvarinsky
stone slab, has the same parameters as the ellipse from the wells on the slab
of the kurgan field Tavriya -1, discovered in the Rostov region, too. With the
help of astronomical methods previously been proved that elliptically located
wells on the Srubna slabs are hour markers of analemmatic sundial. By results
of the use of similar methods to study complex of petroglyphs on Varvarinsky
slab, it was concluded that the slab could be used for development of the
technology of markup of sundial on different geographical latitudes. Also,
Varvarinsky slab could serve as a model example for a markup of the ellipse on
which subsequently extorted wells for latitudes, close to the latitude of the
place of slab detection. Thus, Varvarinsky stone slab is the prototype of
analemmatic sundials, discovered in the Rostov and Donetsk oblasts. analemmatic
