The evidence that the Mexicans regarded the form of the courtyard, named tlachtli, as that of the state itself is noteworthy. On the other hand, the native map contained in the Codex Mendoza, p. 1, shows us that they figured their territory as a square, surrounded by water and divided into four equal parts by diagonal cross-streams or canals. As in the Maya map the centre of this is occupied by the well-known hieroglyph or rebus of Te-noch-ti-tlan, the ancient capital, which consisted of Mexico and Tlatelolco. In three of the four triangular divisions, two chieftains are figured, whilst in one there are four, the complete number of chieftains thus being ten. The incontrovertible evidence that the dominion of the Mexicans, as well as that of the Mayas, was figured and regarded as an integral whole has seemed to me to be of extreme importance, because it points to a fresh interpretation of the much-discussed meaning of the name Tullan, “the glorious centre of culture where the high priest Quetzalcoatl, had dwelt and whence he had been driven by the wiles of his enemies. It is a place that we hear of in the oldest myths and legends of many and different races. Not only the Aztecs, but the Mayas of Yucatan and the Kiches and Cakchiquels of Guatemala, bewailed in woful songs, the loss of that beautiful land and counted its destruction as the common starting-point in their annals.... According to the ancient Cakchiquel legends, however, ... ‘there were four Tullans, as the ancient men have told us.’ The most venerable traditions of the Maya race claimed for them a migration from Tullan in Zuyva.”... “When it happened to me,” says Friar Duran, “to ask a [Mexican] Indian who cut this pass through the mountains or who opened that spring of water or who built that old ruin? the answer was: The Tultecs, the disciples of Papa,” _i. e._, Quetzalcoatl. (See Brinton, American Hero-Myths, p. 88.) Considering that the identity of Tullan has not yet been satisfactorily established, that several Tullans are said to have existed and that a small town, about a dozen leagues to the northeast of Mexico, is named Tullan-tzinco=little Tullan, I should like to direct the attention of Americanists to the following Maya words: Tul-um=fortification, edifice, wall and enclosure. Tula-cal, Tuliz, adjectives=whole, entire, undivided, integral. Tul-ul, adjective=general, universal. Tul-tic, verb=to belong, to correspond to something. Tul=all around or full. Tul=in composition, to have abundance. Tulnah=to be too full, to overflow, to proceed, to issue, abound, high-tide. Tulaan=past participle of tul.
