The painter, of Riojan origin, completed his artistic formation with Jean Changenet in Avignon (doc. 1493). When he returned to Castile he worked in Palencia and Burgos. The simplification of volumes in his work and the importance given to light show the influence of Provencal art. Besides the sculptural image of the bishop and saint, there is a striking contrast between the realist design of the pavement and the decorative gold sgraffito background. The inscription on the halo allows us to identify the saint, who also has a mitre and crook.
