Castile,end of the fifteenth century Spanish painter. He is named from St Ildefonso's Reception of a Chasuble from the Virgin Mary (Paris, Louvre), which is traditionally held to come from Valladolid; it may even have come from the chapel of S Ildefonso in the Colegiata there. The style, characterized by harmony of colour and intense expressions, resembles that of four panels of St Athanasius, St Louis of Toulouse, both enthroned, SS Peter and Paul and SS Andrew and James the Great, which probably came from the convent of La Merced, Valladolid. They have been attributed to the Master of vila, but Post considered them to be the work of the Master of St Ildefonso, a more sophisticated painter, although both artists modified the harshness of their Netherlandish models. There are also similarities with Jacomart's triptych of St Anne in the Colegiata, Jetiva, but these may be coincidental. Other works attributed to the Master include St Anne and St Anthony of Padua,
