Let us now transport ourselves, mentally, south of the peninsula to Honduras and, leaving the coast, ascend the Motagua valley to the ruins of Quirigua and Copan,(61) which have impressed Mr. Maudslay as being of great antiquity. Before examining such of these monuments as seem to yield the testimony we are seeking, let us again recall Landa’s record that the Mayas erected stelæ as memorials of each 20-year period. To this statement should be added, at full length, Cogolludo’s record that “the Mayas employed eras of 20 years and lesser periods of 4 years.(62) The first of these four years was assigned to the east and was named Cuch-haab; the second, Hiix, to the west; the third, Cavac, to the south and the fourth Muluc, to the north, and this served as a ‘Dominical letter.’ When five of these four-year periods had passed, which form twenty years, they called it a Katun and placed one sculptured stone over another sculptured stone and fixed them with lime and sand [mortar] to the walls of their temples and houses of the priests.”(63) The term katun is closely linked to the said employment of memorial stones, for tun is the Maya for stone and ka seems to stand for kal or kaal=20. The word hun-kaal=20, means literally, “one complete count,” or “a count which is closed,” since the verb kaal means to close, shut, or fasten something. According to the above a katun literally means “the 20 (year) stone;” but we know that, by extension, it designated the era itself as well as war and battle. Thus we find the verb katun-tal=to fight. Cogolludo continues: “In a town named Tixuala-tun, which signifies ‘the place where they place one stone above another,’ they say that they kept their archive, containing records of all events.... In current speech katun signified era and when a person wished to say he was sixty years of age, he used the expression to have three eras of years or three stones. For seventy they said three and a half stones or four less one-half stone. From this it may be seen that they were not too barbarous, for it is said that [by this system] they were able to keep such exact records that they not only certified an event but also the month and day on which it took place.” By referring to Maya and Spanish dictionaries we gain supplementary valuable information about native memorial stones. We find the name amaytun given as that of “a square stone on which the ancient Indians used to carve the 20 years of the period ahau-katun, because the four remaining years which completed the epoch, were placed underneath, so as to form a sort of pedestal which was called, for this reason, lath oc katun or chek oc katun. By extension, painted representations [of the epoch] were also named amaytun.” The dictionary further informs us that amayté was the name for the first twenty years of the ahau katun, which were carved on the square stone and we see that amayté also means “something square or with corners” and is formed of amay=corner.
