Biography

There is scarcely any information regarding the life of this artist. It was Angulo (1940) and Post (1947) who brought his figure to light and suggested the possibility that he trained alongside the Master of Becerril. The latter considered that, although he carried out numerous works in Valladolid, his workshop was located in Ávila. Redondo Cantera (1991) claimed that his name was Álvaro, based on an inscription found in San Miguel del Pino (Valladolid). However, Puig Sanchis (2020) has recently refuted this idea. Regardless, several works have been attributed to the Master of Portillo, which are now held in both national and international museums and institutions. Examples include: The Burial of Christ (Museum of San Isidro, Madrid) and The Mass of Saint Gregory (Museum of Fine Arts, Budapest).
