That this culture-hero arrives from the East and returns to the East are points that at once excite the suspicion that he was the personification of the Light. But when we come to his names, no doubt can remain. These were various, but one of the most usual was _Chimizapagua_, which, we are told, means "a messenger from _Chiminigagua_." In the cosmogonical myths of the Muyscas this was the home or source of Light, and was a name applied to the demiurgic force. In that mysterious dwelling, so their account ran, light was shut up, and the world lay in primeval gloom. At a certain time the light manifested itself, and the dawn of the first morning appeared, the light being carried to the four quarters of the earth by great black birds, who blew the air and winds from their beaks. Modern grammarians profess themselves unable to explain the exact meaning of the name _Chiminigagua_, but it is a compound, in which, evidently, appear the words _chie_, light, and _gagua_, Sun.[1] [Footnote 1: Uricoechea says, "al principio del mundo la luz estaba encerrada en una cosa que no podian describir i que llamaban _Chiminigague_, ó El Criador." _Gramatica de la Lengua Chibcha_, Introd., p. xix. _Chie_ in this tongue means light, moon, month, honor, and is also the first person plural of the personal pronoun. _Ibid_., p. 94. Father Simon says _gagua_ is "el nombre del mismo sol," though ordinarily Sun is _Sua_.] Other names applied to this hero-god were Nemterequeteba, Bóchica, and Zuhe, or Sua, the last mentioned being also the ordinary word for the Sun. He was reported to have been of light complexion, and when the Spaniards first arrived they were supposed to be his envoys, and were called _sua_ or _gagua_, just as from the memory of a similar myth in Peru they were addressed as Viracochas. In his form as Bóchica, he is represented as the supreme male divinity, whose female associate is the Rainbow, Cuchaviva, goddess of rains and waters, of the fertility of the fields, of medicine, and of child-bearing in women, a relationship which I have already explained.[1] [Footnote 1: The principal authority for the mythology of the Mayscas, or Chibchas, is Padre Pedro Simon, _Noticias Historiales de las Conquistas de Tierra Firme en el Nuevo Reyno de Granada_, Pt. iv, caps. ii, iii, iv, printed in Kingsborough, _Mexican Antiquities_, vol. viii, and Piedrahita as above quoted.] Wherever the widespread Tupi-Guaranay race extended--from the mouth of the Rio de la Plata and the boundless plains of the Pampas, north to the northernmost islands of the West Indian Archipelago--the early explorers found the natives piously attributing their knowledge of the arts of life to a venerable and benevolent old man whom they called "Our Ancestor," _Tamu_, or _Tume_, or _Zume_.
