Ixtlilton (Nahuatl languages: Īxtlīltōn in Nahuatl languages pronounced as /iːʃˈt͡ɬiːɬtoːn/,"ink at the face", from īxtli, "face", "eye", tlīlli, "black ink", and -tōn, diminutive suffix[1] [2]) in Aztec mythology is a god of medicine and healing[3] and therefore was often alluded to as the brother of Macuilxochitl, the god of well-being or good luck. Ixtlilton was a gentle god, who emanated from an obsidian mask which brought darkness and peaceful sleep to children in their beds at night.[4]
