Giovanni Battista Salvi, better known as Sassoferrato, painted The Virgin in Prayer between 1640 and 1650. Executed in oil on canvas, the work measures 73 × 57.7 cm and is now part of the National Gallery, London. Though he also produced large-scale altarpieces, Sassoferrato became most celebrated for intimate devotional images of the Virgin, designed for private contemplation and widely collected during the 17th century.
