into shock, a hallucinatory vision occurs." Once the actual bloodletting was over, the blood soaked ceremonial papers were burned, releasing a column of smoke. The smoke provided the perfect medium for the Vision Serpent to appear. Every major political or religious event involved bloodletting because it provided a medium by which the gods could be called upon to witness and actually participate in the ceremony. Sometimes the spirits of ancestors were also called upon to give guidance. The Hauberg Stela (A. D. 199) from the Maya Lowlands "is one of the first dated monuments that depict the Vision Serpent's connection to bloodletting". Lintel 25 depicts one of the bloodletting rituals. "One of Shield Jaguar's wives, is seen gazing up towards an enormous bicephalous Vision Serpent. In her left hand, she holds a bowl containing a stingray spine, an obsidian lancet, and papers spattered with blood. The Vision Serpent appears to be emanating from the bowl. From the jaws of the Vision Serpent, spews forth an ancestral Tlaloc warrior complete with spear and shield". Lintel 17 refers to "Bird Jaguars as Blood Lord of Yaxchilan" and shows him preparing to draw blood from his penis with a stingray spine.

"The serpent can be seen rising out of the bowl with trickles of blood along a column of blood scrolls. This lintel shows the queen of Yaxchilan involved in a visionary experience following an elaborate bloodletting ceremony. She holds the ritual paraphernalia in her arms while the vision serpent rises from a bowl of blood stained paper." Maya religious rites There was a Vision Serpent named Och-Kan, lord of Kalak'mul.
