By this time I trust that my readers will realize with me that, at Copan, the native set of ideas had long taken deep root and flourished. We have seen that the identical numerical divisions of time and tribes and the same symbolism prevailed as have been traced in Peru, Guatemala, Mexico, Yucatan, Zuñi, etc. The following monuments will still further establish this kinship of thought. Copan contains two stone slabs which answer to the description of an amay-tun, inasmuch as they are square and appear to be memorial stones. Let us see whether some clue to their purpose can be obtained from the carvings upon them.
On each of the four sides of altar K four personages are carved, all seeming to be of equal rank. Of these 4×4=16 chieftains, eight wear a breast ornament in the form of a double serpent, whilst the remaining eight wear a somewhat plainer kind. On the west side the two central figures face each other and two diminutive glyphs are carved in the space between them. The most striking feature about the representation of these personages is, that each of them is seated, cross-legged, on a different composite glyph; some of these exhibit animal forms. This is a fact of utmost importance, for it definitely connects distinct personalities, obviously chieftains with composite glyphs, some composite parts of which are obviously totemic. On the upper surface of this monolith there are 6×6=36 single glyphs, which yield 9 groups of 4. If these 9×4 be added to the 4×4 glyphs on which the chieftains are respectively seated, we obtain 13 groups of 4, equivalent to 52. It is superfluous to repeat that there are fifty-two years in the Mexican cycle and that just as this square altar has 16 figures carved around it, the great monolithic Stone of Tizoc in the City of Mexico has 16 groups. In the latter case each group is accompanied by the name of a tribe and its capital. It looks very much as though the glyphs on which the chieftains on Altar K are seated also express tribal names.
A careful study of the other square monolith at Copan, known as the Alligator altar, will enable us to form a better estimate of the probable meaning of glyphs, employed as seats by chieftains. The Alligator altar takes its name from the sculptured animal which is stretched over its upper surface. Human figures are represented as connected with the different parts of the animal's body, in a way which forcibly recalls Mr. Cushing's explanation of how the various members of a tribe were associated with a part only of their totemic animal and bore the name of this part as their title of honor, according to a strict order of precedence.
