Observation made by Stijn van den Hoven
KaliMukha, Kirthimukha (temple faces) are identical to the Medusa and Kali imagery and seen in many other cultures as well as a fanged monster, mostly associated with serpents or serpent hair.
In meso american art she is Coatlicue.
Either depicted as a monster above doorways or in temple art.
I suspect this is a metaphor for time itself devouring creation. It later transformed into the Siren symbolism and mother godess symbolism but its origina might be the sun/moon disk with the two snakes as seen in Egypt.
