Proximity of place had no part in this similarity of rite. In the grand commemorative festival of the Creeks called the Busk, which wiped out the memory of all crimes but murder, which reconciled the proscribed criminal to his nation and atoned for his guilt, when the new fire was kindled and the green corn served up, every dance, every invocation, every ceremony, was shaped and ruled by the application of the number four and its multiples in every imaginable relation. So it was at that solemn probation which the youth must undergo to prove himself worthy of the dignities of manhood and to ascertain his guardian spirit; here again his fasts, his seclusions, his trials, were all laid down in fourfold arrangement.[72-1] Not alone among these barbarous tribes were the cardinal points thus the foundation of the most solemn mysteries of religion. An excellent authority relates that the Aztecs of Micla, in Guatemala, celebrated their chief festival four times a year, and that four priests solemnized its rites. They commenced by invoking and offering incense to the sky and the four cardinal points; they conducted the human victim four times around the temple, then tore out his heart, and catching the blood in four vases scattered it in the same directions.[72-2] So also the Peruvians had four principal festivals annually, and at every new moon one of four days' duration. In fact the repetition of the number in all their religious ceremonies is so prominent that it has been a subject of comment by historians. They have attributed it to the knowledge of the solstices and equinoxes, but assuredly it is of more ancient date than this. The same explanation has been offered for its recurrence among the Nahuas of Mexico, whose whole lives were subjected to its operation. At birth the mother was held unclean for four days, a fire was kindled and kept burning for a like length of time, at the baptism of the child an arrow was shot to each of the cardinal points. Their prayers were offered four times a day, the greatest festivals were every fourth year, and their offerings of blood were to the four points of the compass. At death food was placed on the grave, as among the Eskimos, Creeks, and Algonkins, for four days (for all these nations supposed that the journey to the land of souls was accomplished in that time), and mourning for the dead was for four months or four years.[73-1] It were fatiguing and unnecessary to extend the catalogue much further. Yet it is not nearly exhausted. From tribes of both continents and all stages of culture, the Muyscas of Columbia and the Natchez of Louisiana, the Quichés of Guatemala and the Caribs of the Orinoko, instance after instance might be marshalled to illustrate how universally a sacred character was attached to this number, and how uniformly it is traceable to a veneration of the cardinal points. It is sufficient that it be displayed in some of its more unusual applications.
