Granadine heavy cavalryman, mid-13th century

Granadine heavy cavalryman, mid-13th century
Ian Heath based his Granadine heavy cavalryman, mid-13th century on the manuscripts of the Cántigas of Alfonso X.
Perhaps on a combination of these images:
Panel 4, Cantiga 63: Muslim soldiers under Almanzor (al-Mansur) attack San Esteban de Gormaz, in 989 CE
Panel 5, Cantiga 165: The next day, the Sultan ordered his troops to take the city
Panel 5, Page 1 Cantiga 187: The King of Granada immediately rallied his troops and headed for the castle. He forced the castellan to demand its surrender, but the defenders refused to give in.
Page 2 Cantiga 187: The Statue that Defended a Castle

or is there another cantiga that shows this type of heavy cavalryman?
