Not my most successful painting, but I’m posting it anyway. I had a hard time painting such tiny details on such a small sketch card. (What you are seeing onscreen is larger than actual size.)
Cipactli is a primordial crocodile-fish-frog monster so ravenous that it has an extra maw at every joint in its body. In Aztec mythology, the god Tezcatlipoca lost a foot when he used it as bait to capture Cipactli. Tezcatlipoca and Quetzalcoatl then formed the earth from Cipactli’s body.
