Mural with roundel

Upon entering the church from the main, West façade, to the immediate left under the sotocoro is a large, rectangular mural with a central medallion or roundel in which an Otomi warrior wearing coyote garb vanquishes a Chichimec. To either side, amidst heavy acanthus foliage, victorious fighters with speech scrolls are seen above while below appear dismembered bare legs, pieced by arrows.
