like that described in the Popol Vuh Twin myth. The Yucatec Maya had a double concept of the afterlife: Evildoers descended into an underworld (metnal) to be tormented there (a view still held by the 20th-century Lacandons), while others, such as those led by the goddess Ixtab, went to a sort of paradise. The ancestors of Maya kings (Palenque tomb of Pakal, Berlin pot) are shown sprouting from the earth like fruit trees which, together, constitute a blissful orchard. The so-called 'Flower Mountain' has more specifically been interpreted as a reference to an aquatic and solar paradise. To judge by the marine faunal remains found in Classic tombs and by the accompanying aquatic imagery, this sea paradise may have been the Maya variant of the rain god's paradise (Tlalocan) in Central Mexican religion. Powers of the Other World Ancestors The traditional Maya live in the continual presence of the '(grand)fathers and (grand)mothers', the usually anonymous, bilateral ancestors, who, in the highlands, are often conceived of as inhabiting specific mountains, where they expect the offerings of their descendants. In the past, too, the ancestors had an important role to play, with the difference that, among the nobility, genealogical memory and patrilineal descent were much more emphasized. Thus, the Popol Vuh lists three genealogies of upper lords descending from three ancestors and their wives. These first male ancestors – ritually defined as 'bloodletters and sacrificers' – had received their private deities in a legendary land of origins called 'The Seven Caves and Seven Canyons' (Nahua Chicomoztoc), and on their disappearance, left a sacred bundle. Already during the Classic period, ancestral deities (the three 'patron deities' of Palenque) and ancestral bundles (Yaxchilan) are in evidence. In Chiapas at the time of the Spanish conquest, lineage ancestors were believed to have emerged from the roots of a ceiba tree; comparable beliefs still exist amongst the Tz'utujiles. Heroes Within the group of the ancestors, a special category is constituted by the heroes, best known through the sixteenth-century Quichean epic of the Maya hero twins, Hunahpu and Xbalanque. In the Classic period, the adventures of these two heroes – only partly coinciding with those of the Popol Vuh – were known all over the Mayan area. Specific ancestral heroes occur among various traditional Maya groups, such as the dwarfish Ez among the Yucatec Mayas; Juan K'anil among the Jacaltecs of the northwestern highlands; Ohoroxtotil, the jaguar
