After the closure of the monastery of Holy Cross of the ‘comendadoras de Santiago’ in Valladolid at the beginning of the 1980s, its heritage was dispersed in numerous religious and museum institutions; however, the track of one of the sculptures of the main altarpiece was lost, specifically that of King St Ferdinand. Recently in an auction house in Barcelona has appeared a work of the aforementioned Castilian monarch that, with a different head, we have identified as the one that disappeared from the female monastery of the Order of Santiago in Valladolid.
