I am of opinion that, after carefully examining the foregoing words and their meanings, we must admit that an intelligible and satisfactory derivation and signification of the much-discussed Tula of the Mexicans, which has been vainly sought in the Nahuatl language, are obtained if we connect it with the Maya words for fortress, or stronghold, an enclosed place, an integral whole, an overflowing source of abundance and plenty. If we do this, then the problematic term Tolteca, given by Mexicans to the superior people from whom they had derived their culture and knowledge, means nothing more than such persons who had belonged (Maya verb tultic) or were members of a highly cultured commonwealth or ancient centre of civilization, such as had flourished during countless centuries, in Yucatan and the present Chiapas, Honduras and Guatemala. Reserving this subject for future, more detailed, discussion, I point out that the name Ho, given to the capital, which is designated in the map as the “head of the land,” is obviously derived from the Maya hol, hool, or hoot, which means not only head but also chieftain. The circumstance that a single word, Ho, conveyed the triple meaning of a capital, a chieftain and a head, is particularly noteworthy, as it affords not only important clues to native symbolism, which I shall trace later on, but also shows that the presence of the syllable Ho or O, in certain native names of localities, may possibly indicate that it was a capital, the residence of a chieftain. Further light is shed upon the following native association of ideas when the following words are studied. The ancient Maya name for a pyramid or artificial mound was ho-m and the pyramidal elevations on which temples or palaces were built were designated as ho-mul or o-mul (see Vocabulary, Brasseur de Bourbourg). The title Holpop was moreover that of the “chieftain of the mat,” whose prerogative it was to sit on a mat and to beat the sacred drum during the public dances or ritual performances (Cogolludo). The ancient word for vase, vessel or cup in general was ho-och, whilst o-och meant food or maintenance (Arte de la lengua Maya, Fray Beltram de Santa Rosa, ed. Espinosa, Merida, 1859). If the foregoing data be summarized we find that the word ho, the ancient name of the head of the land, which is figured in its centre, is not only homonymous with capital and chieftain, but also with pyramid, vase or receptacle and maintenance, and finally with the numeral 5, also “ho.” We shall see that the identical ideas were similarly associated in ancient Mexico.
