A decorative belt in the form of an indented frieze, which in Pskov is called a “runner” (begunok or begunets), surrounds the drums supporting the domes and graces the apses of Pskov churches to form one of their most distinguishing features. It consists of three bands, the two outer ones formed of quadrangles, while the inner one is made up of interlocking triangles whose apexes alternately point upward and downward (fig. 1). Above the begunki, on the drums, usually there are additional decorative “brows” formed by a series of indented arches. But these are not unique to Pskov and will not be dealt with in this paper. The ornamentation on the apses usually is composed solely of the Pskov begunok.
