[III-72] The date of the arrival in Huehue Tlapallan is given by Ixtlilxochitl in his first Toltec relation (p. 322) as 2236 years after the creation, or 520 years after the flood. That is, it occurred long before the Christian era. In other places (pp. 206, 459) the same author represents the Toltecs as banished from their country and migrating to Huitlapalan in California on the South Sea in 387 A.D., whence they continued their journey to Tulancingo. Now, although I attach very little importance to this author's chronology, and shall enter into no discussion with a view either to reconcile or overthrow it, yet it is plain that this last statement, notwithstanding the use of the name Huitlapalan, refers to a migration long subsequent to that mentioned in the text. The date 387 A.D., therefore, given by Gallatin, (in _Schoolcraft's Arch._, vol. v., p. 96) and Müller, (_Reisen_, tom. iii., p. 97), as that of the arrival in Huehue Tlapallan, according to Ixtlilxochitl, is calculated to convey a false impression.
[III-73] Ixtlilxochitl, p. 322, says it was 305 years after the death of Christ, or about 338 A.D.; but on the same page he again makes the date 439 A. D. Veytia, tom. i., p. 208, dates the rebellion 583, the exile 596, and the founding of Tlapallanconco 604 A.D. Clavigero, tom. iv., p. 46, gives 544 as the date of departure, but on p. 126 of tom. i., he gives 596, agreeing with Veytia. Müller, in his tables, _Reisen_, tom. iii., p. 97, dates the outbreak of war 427, the departure 439, the migration 447 A.D. Brasseur, _Popol Vuh_, p. clv., gives the last of the fourth century as the date of the Toltec migration. Cabrera, _Teatro_, pp. 90-1, makes the date 181 B.C. 544 A.D., one of Clavigero's dates, is that which has, perhaps, been most commonly adopted by modern writers.
[III-74] Brasseur, _Hist. Nat. Civ._, tom. i., p. 126, writes this name Tlapallantonco; and in _Popol Vuh_, p. clix., he insists that it should be Tlapallantzinco. Müller, _Reisen_, tom. iii., p. 98, calls it also Tlappallanzingo.
[III-75] Ixtlilxochitl, p. 324, makes this third year 543, and their arrival in Tulancingo consequently 540 A.D.; or as is implied on p. 307, 487 A.D.; or adding 104 years to the first date given by this author in note 71, we have 442 A.D. Veytia, tom. i., p. 221, 697 A.D. _Id._, after Boturini, in _Tezcoco en los Ultimos Tiempos_, 687 A.D. Müller, _Reisen_, tom. iii., p. 97, 558 A.D. Clavigero, tom. iv., p. 51, 648 A.D., or tom. i., p. 126, 700 A.D.
