Finally, if we should assume that the series went on across page 25, to a full katun-round of 20 terms, the circuit would be broken; line 2 would not regularly follow line 1, and so on. The probabilities then, as derived from the succession of the days, seem almost conclusive that this is a section of 65 terms, to be read horizontally, in whichever direction. 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. What part the blue[34-*] number series plays, I cannot say. Dr. Seler,[34-†] suggests that they are “corrections,” to set each term ahead 20 days. This states a fact, but does not give any explanation. Each blue number is 6 less than its red column, and 7 Kan _is_ of course 20 days later than 13 Kan. FOOTNOTES: [24-*] Dr. Förstemann (_Comm. z. Par. Mayahds._) speaks of the background to the central figure on page 16 as black, instead of red; he also describes the number columns as made up of red and black numerals only. There are many similar errors in his Commentary, due to his ignorance of the colors, and to the obscurity of the photographic reproductions. [28-*] Where to place the Tro.-Cort., in view of the _apparent_ Kan, Muluc[TN-3] Ix, Cauac years indicated on pages 34-37, and the 13 Cumhu immediately next to 13 Ahau on page 73 (13 Ahau 13 Cumhu falling only possibly in a year 12 Lamat) I am not ready to say. [29-*] Mr. Bowditch suggests to me that the numbers 1 2 3 3 5 6 6 are to be read with each of the day signs in their respective columns, and, being placed in the middle, may apply both to the upper and lower sets. The strongest objection I can see to this is that the numbers are black, instead of the usual red. In this case, instead of intervals of 8 and 16, giving rounds of 5×8=40 and 5×16=80 days, we would have intervals of 156 and 208 (from 1 Ymix to 1 Muluc, etc.), giving rounds of 780 and 1040 days respectively. Or, if read _upwards_, we would have 52 and 104 day intervals (1 Ben to 1 Chicchan, etc.), and rounds of 260 and 520 days. But whichever be the case, the page is _sui generis_, and its why is still beyond us. [31-*] I have retained the usual term “shields” for the flaring forms which embrace the sun glyph, though without accepting its appropriateness. They might with equal likelihood be conventionalized wings.
