Circumcision of the Polyptych of the Main Chapel of the Cathedral of Viseu

Grão Vasco painted this Circumcision for the Viseu Cathedral Polyptych around 1503. The extensive altarpiece program for the cathedral's main chapel was his most ambitious commission, encompassing numerous panels depicting the life of Christ and the Virgin. These panels represent the pinnacle of early 16th-century Portuguese painting. The oil medium allowed for rich tonal transitions and glazed layers of color that created luminous depth impossible with the older tempera technique. Such devotional panels served both liturgical contexts in churches and chapels and private devotional use in the homes of wealthy families who maintained personal altars and oratories.

Oil on panel with careful rendering of the ritual scene. Grão Vasco's technique shows the influence of Netherlandish painting transmitted through Portuguese artistic contacts with Flanders.
