Virgen del Rosario con el Niño Jesús, by Bartolomé Esteban Murillo, right, will feature in the next auction at Alcalá Subastas on October 4-5.
Depicting the Virgin and Child on a simple, black background and measuring 5ft 6in x 3ft 8in (1.68 x 1.12m), the oil painting is thought to have been commissioned directly by the Carmelites Calzados for the sacristy of their convent in Seville.
