Spanish Heavy Infantry in Biblia Segunde de San Isidoro de Leon, 1162

Ian Heath's Spanish Heavy Infantryman in Armies of the Dark Ages 600-1066 is supposed to be based on an 11th century source, but it appears to be from Biblia Segunde de San Isidoro de Leon, of 1162AD. The shield matches one in King David sends his army to fight his son Absalom
Is there an 11th century source that matches?

To compare the 1162 bible with the 960 bible that it was copied from, compare these similar scenes:
a battle with cavalry in Biblia de San Isidoro de Leon, 960 with
the pursuit of the Philistines in Biblia Segunde de San Isidoro de Leon, 1162;

An army in Biblia de San Isidoro de Leon, 960 with
King David sends his army to fight his son Absalom in Biblia Segunde de San Isidoro de Leon, 1162;

and these portraying the same scene:
Goliath in Biblia de San Isidoro de Leon, 960 with
Goliath in Biblia Segunde de San Isidoro de Leon, 1162. These 2 have a similar compostion including terrain at bottom-left and bottom-right. The text has Goliath in armour so the pattern in the 960 bible would represent this armour.
