er informed in Mexican
antiquity. The system of this gentleman is fantastical and full of
contradictions."

From this statement we infer that Siguenza held the same opinion on this
point as Clavigero and Gemelli.

Boturini[30] gives the following arrangement of the "symbols of the four
parts or angles of the world," comparing it with that of Gemelli.

"Gemelli. "Boturini.

1. Tochtli = South. 1. Tecpatl = South.
2. Acatl = East. 2. Calli = East.
3. Tecpatl = North. 3. Tochtli = North.
4. Calli = West." 4. Acatl = West."

SYMBOLS OF THE FOUR ELEMENTS.

"Gemelli. "Boturini.

1. Tochtli = Earth. 1. Tecpatl = Fire.
2. Acatl = Water. 2. Calli = Earth.
3. Tecpatl = Air. 3. Tochtli = Air.
4. Calli = Fire." 4. Acatl = Water."

Herrera speaks only of the year symbols and colors, and, although he
does not directly connect them, indicates his understanding in regard
thereto by the order in which he mentions them:[31]

"They divided the year into four signs, being four figures, the one of a
house, another of a rabbit, the third of a cane, the fourth of a flint,
and by them they reckoned the year as it passed on, saying, such a thing
happened at so many houses or at so many flints of such a wheel or
rotation, because their life being as it were an age, contained four
weeks of years consisting of thirteen, so that the whole made up
fifty-two years. They painted a sun in the middle from which issued four
lines or branches in a cross to the circumference of the wheel, and they
turned so that they divided it into four parts, and the circumference
and each of them moved with its branch of the same color; which were
four, _Green_, _Blue_, _Red_, and _Yellow_; and each of those parts had
thirteen subdivisions with the sign of a house, a rabbit, a cane, or a
flint."

From this statement I presume his arrangement would be as follows:

Calli -- Green.
Tochtli -- Blue.
Acatl -- Red.
Tecpatl -- Yellow.

Still, this is at best but a supposition. It is evident that he had
before him or referred to a wheel similar to that figured by Duran in
his _Historia de las Indias_, as his description agrees with it in every
respect, except as to the arrangement of the colors.

According to Duran[32] "The circle was divided into four parts, each
part containing thirteen years, the first part pertaining to the east,
the
