Master of Holy Blood (c1470 - c1520). The Master of the Holy Blood was an anonymous 15th-century painter or group of painters active in Bruges, Belgium, during the Northern Renaissance. Named after an altarpiece depicting the Lamentation of Christ in the Basilica of the Holy Blood, the artist is known for richly detailed religious works characterized by realistic textures, emotional depth, and intricate landscapes. Influenced by Early Netherlandish masters like Rogier van der Weyden and Quentin Massys, the Master of the Holy Blood produced devotional art that captured the dramatic intensity of the Passion of Christ and other sacred themes, blending idealization with realism in figures and settings. Active during a flourishing period for art in Bruges, the artist’s works, often commissioned by wealthy patrons, remain important for understanding the religious and cultural dynamics of the time.
