This painting is quite large; unfortunately, I couldn't ascertain its exact dimensions. However, it proudly hangs high above the central courtyard of the Museum in Siguenza. You can view it directly from the second-floor gallery.
It depicts the Battle of Alcoraz, an armed encounter that took place on November 15, 1096, near Huesca, involving Aragonese and Pamplona troops on one side and Muslim troops from Zaragoza supported by Castilian forces on the other.
