According to this writer, the other names applied to the _Bacab_ of Kan, were _Hobnil_, _Kanil-Bacab_, _Kan-Pauahtun_, and _Kan-Xib-Chac;_ to that of Muluc, _Canzienal_, _Chacal-Bacab_, _Chac-Pauahtun_, and _Chac-Xib-Chac;_ to that of Ix, _Zac-Ziui_, _Zacal-Bacab_, _Zac-Pauahtun_, and _Zac-Xib-Chac;_ and to that of Cauac, _Hozen-Ek_, _Ekel-Bacab_, _Ek-Pauahtun_, and _Ek-Xib-Chac_. As _Kan_ or _Kanil_ of the first signifies _yellow_, _Chac_ or _Chacal_ of the second signifies _red_, _Zac_ or _Zacal_, of the third _white_, and _Ek_ or _Ekel_, of the fourth _black_, it has been assumed, and, I think, correctly, that these colors were usually referred to these days, or rather to the cardinal points indicated, respectively, by these day symbols. If there is any other authority for this conclusion in the works of the earlier writers, I have so far been unable to find it. If the figures in our plate are properly and distinctly colored in the original Codex Cortesianus, this might form one aid in settling this point, but, as we shall hereafter see, the colors really afford very little assistance, as they are varied for different purposes. Rosny gives us no information on this point, hence our discussion must proceed without this knowledge, as we have no opportunity of referring to the original. I may remark that it is the opinion of the artist, Mr. Holmes, from an inspection of the photograph, that the plate was at least partially colored. M. de Charencey, who has studied with much care the custom of identifying colors with the cardinal points in both the New and Old World, believes that in Mexico and Central America the original system was to refer yellow to the east, black to the north, white to the west, and red to the south.[25] When we turn to the Mexican system we find the data greatly increased, but, unfortunately, the difficulties and confusion are increased in like proportion. Here we have not only the four dominical days and the four colors, but also the four ages, four elements, and four seasons, all bearing some relation in this system to the four cardinal points. It will be necessary, therefore, for us to carry along with us these several ideas in our attempt to arrive at a satisfactory conclusion on this complicated and mystified subject.
