Youth; as potent and unpersuadable, he was _Moyocoyatzin_, the Determined
Doer;[1] as exacting in worship, _Monenegui_, He who Demands Prayers; as
the master of the race, _Teyocoyani_, Creator of Men, and _Teimatini_,
Disposer of Men. As he was jealous and terrible, the god who visited on
men plagues, and famines, and loathsome diseases, the dreadful deity who
incited wars and fomented discord, he was named _Yaotzin_, the Arch Enemy,
_Yaotl necoc_, the Enemy of both Sides, _Moquequeloa_, the Mocker,
_Nezaualpilli_, the Lord who Fasts, _Tlamatzincatl_, He who Enforces
Penitence; and as dark, invisible and inscrutable, he was _Yoalli
ehecatl_, the Night Wind.[2]

[Footnote 1: _Moyocoyatzin_, is the third person singular of _yocoya_, to
do, to make, with the reverential termination _tzin_. Sahagun says this
title was given him because he could do what he pleased, on earth or in
heaven, and no one could prevent him. (Historia de Nueva España, Lib. III.
cap. II.) It seems to me that it would rather refer to his demiurgic,
creative power.]

[Footnote 2: All these titles are to be found in Sahagun, _Historia de
Nueva España_.]

He was said to be formed of thin air and darkness; and when he was seen of
men it was as a shadow without substance. He alone of all the gods defied
the assaults of time, was ever young and strong, and grew not old with
years.[1] Against such an enemy who could hope for victory?

[Footnote 1: The description of Clavigero is worth quoting: "TEZCATLIPOCA:
Questo era il maggior Dio, che in que paesi si adorava, dopo il Dio
invisible, o Supremo Essere. Era il Dio della Providenza, l' anima del
Mondo, il Creator del Cielo e della Terra, ed il Signor di tutle le cose.
