(18) The princes of Xibalba (so the Popol Vuh recounts) sent their four owl messengers to Hunhun-ahpu and Vukub-hunhun-ahpu, ordering them to come at once to the place of initiation in the fastnesses of the Guatemalan mountains. Failing in the tests imposed by the princes of Xibalba, the two brothers--according to the ancient custom--paid with their lives for their shortcomings. Hunhun-ahpu and Vukub-hunhun-ahpu were buried together, but the head of Hunhun-ahpu was placed among the branches of the sacred calabash tree which grew in the middle of the road leading to the awful Mysteries of Xibalba. Immediately the calabash tree covered itself with fruit and the head of Hunhun-ahpu "showed itself no more; for it reunited itself with the other fruits of the calabash tree." Now Xquiq was the virgin daughter of prince Cuchumaquiq. From her father she had learned of the marvelous calabash tree, and desiring to possess some of its fruit, she journeyed alone to the somber place where it grew. When Xquiq put forth her hand to pick the fruit of the tree, some saliva from the mouth of Hunhun-ahpu fell into it and the head spoke to Xquiq, saying: "This saliva and froth is my posterity which I have just given you. Now my head will cease to speak, for it is only the head of a corpse, which has no more flesh."
