 Also of note in Juxtlahuaca is a painting of a red Feathered Serpent with green plumes, near a red jaguar whose large ears and eyes give it a youthful cast.A design that has provisionally been interpreted as a temple was found on a stalagmite.The cave paintings have been known since at least the 1920s, but were first professionally documented in the early 1960s by Gillett Griffin of Princeton University and Carlo T. E. Gay, an Italian businessman.
