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 second to the north, the third to the west, and the fourth to the south. The first part, which pertained to the east, was called the thirteen years of the Cane, and in each house of the thirteen was painted a cane, and the number of the corresponding year. * * * The second part applied to the north, in which were other thirteen houses (divisions), called the thirteen houses of the Flint, and there were also painted in each one a flint and the number of the year. * * * The third part, that which appertained to the west, was called the thirteen Houses; there were also painted in this thirteen little houses, and joined to each the number of the year. * * * In the fourth and last part were other thirteen years called the thirteen houses of the Rabbit, and in each of these houses were also likewise painted the head of a rabbit, and joined to it a number.”
The plate or figure accompanying this statement[33] is a wheel in the form shown in [Fig. 8], the quadrant a green, with thirteen figures of the cane in it; b red, with thirteen figures of the flint in it; c yellow with thirteen figures of the house in it, and d blue, with thirteen figures of the rabbit’s head in it, each figure with its appropriate numeral. At the top is the word “Oriente,” at the left “Norte,” at the bottom “Occidente,” and at the right “Sur.”
Although this figure was evidently made by this author or for him, it expresses his understanding of the assignment of the years and arrangement of the colors as ascertained from the data accessible to him.
His arrangement will therefore be as follows:
| Acatl | — | East | — | Green. |
| Tecpatl | — | North | — | Red. |
| Calli | — | West | — | Yellow. |
| Tochtli | — | South | — | Blue. |
We find the same idea frequently expressed in the codices now accessible, as, for example, the Borgian and the Vatican B, though the colors do not often correspond with Duran’s arrangement.
