His words clearly indicate that we have here to do with a myth relating to the formation of the calendar, an opinion which can likewise be supported from other sources.
The natives affirmed, says Las Casas, that in ancient times there came to that land twenty men, the chief of whom was called "Cocolcan," and him they spoke of as the god of fevers or agues, two of the others as gods of fishing, another two as the gods of farms and fields, another was the thunder god, etc.

They wore flowing robes and sandals on their feet, they had long beards, and their heads were bare.

They ordered that the people should confess and fast, and some of the natives fasted on Fridays, because on that day the god Bacab died; and the name of that day in their language is _himix_, which they especially honor and hold in reverence as the day of the death of Bacab.[1] [Footnote 1: Las Casas, _Historia Apologetica de las Indias Occidentales_, cap.

cxxii.] In the manuscript of Hernandez, which Las Casas had before him when he was writing his _Apologetical History_, the names of all the twenty were given; but unfortunately for antiquarian research, the good bishop excuses himself from quoting them, on account of their barbarous appearance.

I have little doubt, however, that had he done so, we should find them to be the names of the twenty days of the native calendar month.
