[IV-45] Chalchihuitlicue, Toci, Teteionan, etc. See [vol. iii., p. 350], et seq., [p. 367], et seq.

[IV-46] For description of Xochicalco see [ vol. iv., pp. 483-94].

[IV-47] On Nauhyotl's reign, see Ixtlilxochitl, in Kingsborough's Mex. Antiq., vol. ix., pp. 207, 326, 393, 450, 460; Veytia, Hist. Ant. Mej., tom. i., pp. 255-8; Torquemada, Monarq. Ind., tom. i., p. 37; Clavigero, Storia Ant. del Messico, tom. i., p. 127; Vetancvrt, Teatro Mex., pt ii., p. 11; Brasseur de Bourbourg, Hist. Nat. Civ., tom. i., pp. 319-31. The date 945 is from the Codex Chimalpopoca. The Spanish writers make his reign much longer, all except Clavigero representing him as having reigned, by the consent of his subjects, several years over the time prescribed by law. 979-1035. Veytia. 927-79. Clavigero. 822-80, or 768-826. Ixtlilxochitl. Torquemada and Gomara, as quoted in [note 30], state that this king also marched eastward at the head of a large army to add to his domain by conquest.

[IV-48] Also Xiuhquentzin, Xiuliquentzin, and Xiuhzaltzin, Ixtlilxochitl, and Xiuhzaltzin, Vetancvrt.

[IV-50] Brasseur de Bourbourg, Hist. Nat. Civ., tom. i., pp. 331, 336. Klemm, Cultur-Geschichte, tom. v., p. 181, speaks of an interregnum of forty-eight years after the death of Queen Xiuhtlaltzin.

[IV-51] Called also Yztaccaltzin. Ixtlilxochitl. Atecpanecatl and Iztacquauhtzin. Codex Chimalpopoca and Ixtlilxochitl, according to Brasseur.

[IV-52] 1039, 830, 884, according to the Spanish writers. See [note 47]. Clavigero ignores this king, while Torquemada, followed by Boturini in Doc. Hist. Mex., série iii., tom. iv., p. 230, and Vetancvrt, Teatro Mex., p. 11, seems to identify him with his successor.

[IV-53] Ixtlilxochitl, p. 208, calls the name Quetzalxochitzin, and makes her the wife rather than the daughter of Papantzin.

[IV-54] Bustamante, in Sahagun, Hist. Gen., tom. i., lib. iii., p. 246, erroneously charges Veytia with saying that Papantzin presented to the king a vessel of pulque invented by Xochitl. Brasseur, for reasons not very intelligible, refers to this period Sahagun's account of the invention of pulque in Olmec times (see [pp. 207-8] of this volume), and also the efforts of the sorcerers to make Quetzalcoatl drink pulque that he might be induced to leave Tollan. I have attributed these tales to the times of Ceacatl. See [p. 259] of this volume, also [vol. iii., p. 242], [253], [261].
