About this 3D model

On this lintel at Yaxchilan, the sacrificial offering of blood conjures up a visionary manifestation of Yat-Balam, founding ancestor of the dynasty of Yaxchilan. In the guise of a warrior grasping a spear and shield, this ancestral spirit emerges from the gaping front jaws of a huge double-headed serpent rearing above Lady Xoc. She gazes upward at the apparition she has brought forth. In her left hand she bears a blood-letting bowl containing instruments of sacrifice, a sting-ray spine and an obsidian lancet.
