Rechter Flügel des sog. Pretschlaipfer-Triptychons: Hll. Gregor und Agathe (Innenseite); Hll. Erasmus und Barbara (Außenseite)

The Master of Großgmain takes his name from the altarpiece in the Austrian pilgrimage church of Großgmain and represents a significant late Gothic painter active in Salzburg around 1490–1510. The Pretschlaipfer Triptych right wing, showing Saints Gregory and Agatha on its interior and Saints Erasmus and Barbara on the exterior, deploys four of the Fourteen Holy Helpers — protective saints invoked against specific afflictions. This dual-surface wing format was standard for winged altarpieces and required the painter to design complementary but distinct compositions for interior and exterior display.

The Master of Großgmain works in the Salzburg late Gothic manner with oil over gesso, the figures solid and well-modelled against landscape backgrounds of some spatial ambition. The differentiation between interior saints (shown in richer colours against gold) and exterior saints (more austere, in grey-green architectural settings) follows standard altarpiece convention.
