Zipacna
In Maya mythology, Zipacna was a son of Vucub Caquix (Seven Macaw) and Chimalmat. He and his brother, Cabrakan (Earthquake), were often considered demons. Zipacna, like his relatives, was said to be very arrogant and violent. Zipacna was characterized as a large caiman and often boasted to be the creator of the mountains.
Four hundred boys
The Popol Vuh tells the story that one day Zipacna was basking on the beach when he was disturbed by the Four Hundred Boys (possibly patron deities of alcohol), who were attempting to construct a hut. They had felled a large tree to use as the central supporting log, but were unable to lift it. Zipacna, being immensely strong, offered to carry the log for them, which he did. Although most translations of the Popol Vuh would seem to indicate this was done as a gesture of goodwill, it is generally agreed that Zipacna did so in a spirit of arrogance, mocking the boys for their inability to do so.
The Four Hundred Boys decided it was not good that one man had such strength, and that Zipacna should be killed. They attempted to deceive Zipacna by asking him to dig a hole for their post, intending to thrust the massive column into the hole and kill him. Zipacna realized their deceit, however, and saved himself by surreptitiously digging a side tunnel and hiding inside it when the boys dropped the post in the hole. To complete the illusion of his death, Zipacna cried out in pain, and later allowed ants to carry bits of his hair and trimmings from his nails out of the hole, satisfying the boys that he had been killed.
