The Martyrdom of Saint Lawrence, 1620s, is the only painting by Valentin de Boulogne in the Museo del Prado. One of his most ambitious works, it was almost certainly painted in the mid 1620s. It depicts the martyrdom of Deacon Lawrence (c.225–258), who was executed on a grill for refusing to surrender the Church´s treasures to Emperor Valerian. Instead, the deacon distributed them among the needy.
