Author's note: for the overview post on gods and goddesses of the ancient Maya, go here.
Pauahtun (Pawahtun) is God N of the Schellhas classification. Currently known to have four aspects, he has been connected to an earth god known as Mam described as a god still being worshiped today in Exploring the Life, Myth, and Art of the Maya.
Drawn as an old man with missing teeth, images depict Pauahtun with a turtle shell or a conch shell on his back. He also wears a headdress -- most sources this author has found say it is a netted headdress, though The Ancient Maya: New Perspectives states that it is a crocodile headdress (the book also state that he has a "cut-out shell nose").
The god is also commonly drawn with one hand raised above his head, and is drawn either as a scribe or teaching scribes. In a few Classic period images on ceramics, Pauahtun is drawn with an accompaniment of women.
Pauahtun was the patron of scribes and of group of 5 unlucky days known as the Uayeb (Wayeb), which came at the end of the Haab calendar.
The four aspects of Pauahtun -- called Bacabs (Bakabs) -- each were thought to stand at one of the four main compass points and hold up the sky. Each Bacab was connected to a color as well, like the aspects of Chac (God B).
Pauahtun may be connected to a dance known as the Uayeb (Wayeb) Dance. A scene in the Lower Temple of the Jaguars at Chichen Itzá depicts a ruler and ritual participants taking part in a dance, with Pauahtun being a notable figure. It is conjectured that this dance may have taken place during the Uayeb.
Sources conflict concerning Pauahtun's name. The Ancient Maya states that Pauahtun was known as Bacab during the Postclassic period, while Handbook to Life in the Ancient Maya world states that it is Pauahtun's four aspects that are known as Bakabs. A third source,The Ancient Maya: New Perspectives, states that Pauahtun at the time of contact with the Spanish was known as the four Bacabs.
