 Pourbus was also known for group portraits, such as the wing-panels with portraits of the Members of the Noble Confraternity of the Holy Blood and the Sacra Confrerie of St. Salvator's Cathedral.The position of the sitters in these portraits suggest that Pourbus was influenced by the work of Utrecht-based painter Jan van Scorel.Pourbus followed up on his "Last Judgment" and the "Annunciation" with the smaller Crucifixion in 1557.
