the classic period corresponds to the father of the hero twins in the Popol Vuh called Hun-Hunahpu. However, this once generally accepted identification has also been contested. Cosmological creation myth Linda Schele's emphasis on creation has led to a series of interconnected hypotheses all involving the cosmological centrality of the tonsured maize god (or "first father"), to wit: his establishment of the so-called "three-stone hearth" (assumed to represent a constellation); his raising of the world tree; his "dance of creation"; and his stance as an acrobat, which (more or less coinciding with representations of a crocodile tree) seems to evoke the central world tree. The maize god's presence in the San Bartolo arrangement of five world trees has been interpreted as his establishment of the world. Seasonal myth Another theory, formulated by Simon Martin, focuses on the tonsured maize god's interaction with an aged jaguar deity of trade, God L. This interaction is related to the hero's transformation into a cacao tree conceived as a "trophy tree." God L is assumed to have presided over the dry season dedicated to long-distance trade, warfare, and the cacao harvest, and the Tonsured Maize God over the wet season and the growth of the maize. The onset of the two seasons is thought to be symbolized by the defeat of the maize deity and of God L, respectively. Gulf Coast maize myth In many scenes, an aquatic environment strongly comes to the fore (see fig. 2), most famously in the maize deity's resurrection from the carapace of a turtle that is floating on the waters. Braakhuis pointed out that such an environment also characterizes an important maize myth shared by many ethnic groups (such as Huaxtecs, Totonacs, Nahuas and Zoques) inhabiting Mexico's Gulf Coast. The fact that this myth focuses on a male, rather than a female maize deity, while at the same time establishing an intimate connection between the maize god and the turtle, is adduced in support of the idea that the Classic Maya once formed part of the same narrative tradition. More in particular, the Pre-Classic San Bartolo Mayan maize deity dancing with a turtle drum amidst aquatic deities may have a connection with a Zoque (Popoluca) version of the Gulf Coast maize myth. Names and calendar functions Several designations for the pre-Spanish maize god occur in the Book of Chilam Balam of Chumayel. They include ah mun (tender green
