Periodically interrupting the plain medial molding upon which the mask rests are small flower-like designs with feather-like arrays hanging from their bottoms — which, at least to me, look like small blue ribbons. In The Code of Kings, the Great Mayanist Linda Schele writes that these designs read as itz:
"In Yukatek, itz refers to substances like nectar, tree sap, candle wax, morning dew, and other sacred liquids. Itz also means 'to make magic,' so that this building is a house where magic was made."
Referring to similar decorations at Uxmal, Schele continues: "In ancient Maya parlance, this makes [this building] an Itzam Nah, a 'Conjuring House'. "
