They must ever be important factors in attempts to translate the inscriptions and codices. Another division of time among the Mayas of a complicated character was the Katun or Cycle of 52 years. The Katun was composed of four periods (indictions or weeks) of 13 years each, enumerated by a system of reckoning kept simultaneously with the current reckoning of days, months and years. The mode of computing the Katunes was, according to Landa and Perez, briefly as follows:[628] The year was divided into twenty-eight periods of thirteen days each. These periods for convenience have been called weeks, and the number of days of which each is composed may have been suggested by the number of days embraced in the moon’s _increase_, and _decrease_, twenty-six days constituting about the actual time in which the moon is seen above the horizon during each lunation.[629] The weeks were divided off by counting thirteen days from the beginning of the list of days shown on page 436, Kan constituting the first day of the first week and according to usage applying its name to the weeks. The week was consequently called by the name of the day on which it began. Caban being the fourteenth day of the current month, became the first day of another week; but as not enough days remain to complete it, the enumeration is begun again and continued down to Muluc, the sixth day of the next month. Oc, the seventh day, then becomes the starting point for another week, which assumes its name, and thus the computation is carried on _ad infinitum_. A numeral preceded each day designating its position in the week. The people of Yucatan painted a small circle in which they placed the four hieroglyphics of the initial days which constitute the left-hand column of signs given on page 436. Kan was placed in the east, Muluc in the north, Ix in the west and Cauac in the south. These signs were termed the “carriers of the years” because no month or year could begin on any of the twenty days, but on one of these. Since
