Relief icons constitute a special and rare category of Byzantine sculpture. These works appeared in Middle Byzantine times and continued to be produced in the ensuing period. Several of the relatively small number of relief icons known have been found in Macedonia.
Their subjects include the Virgin, Christ and saints whose cult was popular in the area (Hosios David, Saint Theodora). The discovery of five relief icons in Thessalonike is strong evidence that a workshop producing such objects existed in the city.
