[3] García Sánchez II of Navarre donated the town of Medrano and Sojuela to the Monastery of San Julián with the aim of restoring them.

Queen Estefanía de Nájera, widow of King García Sánchez III of Pamplona, granted her the privilege of joining the villages of Campo, which together with Navarrete, Hornos, Medrano, Entrena, Velilla and Fuenmayor thus benefited from the joint use of water, pastures and paths.

[6] A small panel, measuring 96.5 × 35 cm, originates from Medrano in La Rioja and features a depiction of an unidentified saint bishop on the front, with fragmentary scenes on the reverse, suggesting it was part of a triptych or polyptych.

The saint bishop is shown in full liturgical attire, characterized by vivid colors and a lack of shadows or gradations, typical of the Linear Gothic style.

The reverse side contains small, obscured fragments of scenes, including a monarch and a bishop, likely the same saint depicted on the front, and a young man dressed in period fashion, with signs of intentional damage or alterations.
