And then, since the subdivision of 15,080 days (or 1820, if read right to left) into 65 terms, necessarily gives us successive day-numbers decreasing (or increasing) by 2, the likeness to the katun-series may be only apparent—a simple truism. Or, on the other hand, in view of the glyph similarities (a point which I think should always be given close attention), there may be some relation to the katun-series—all in spite of the right-left or left-right difficulties.
