2) 1,426,360 - 1,366,560 = 59,800.
This number is five times 11,960 days, which is assumed to be the time in which the lunar and Mercury revolutions accord. This 59,800 was found once before on page 24 as the suppressed difference between 68,900 and 9,100.
Thus the separate sections (of the book) are very closely connected.
If the two large numbers be compared with one another their difference will be found to be 39,780. This is equal first to 51 Mars revolutions of 780 days, and second to 4420 × 9, i.e., a multiple of the interval between IV Ahau and XIII Muluc.
Now we must direct our attention to the seventeen hieroglyphs, which we find in the two columns on page 58, apart from the matter-of-course calendar date at the top, which is repeated
at the bottom. One column contains 11 hieroglyphs and the other 6. I will here advance the following theory in regard to these hieroglyphs, which may serve until a better is found:—
Since, as a rule, the Tonalamatl is divided into 5 × 52 days, I believe that each group of three Tonalamatls treated of on page 59, is divided into 15 of these parts; that each hieroglyph, therefore, denotes 52 days and that the first three parts are separated from the others by the signs of beginning and end in the first and fifth places, so that three of these parts, which equal 156 days, always form a separate group. 156 is the 5th part of 780. With the omission of the first and fifth signs, the passage, I think, stands thus:—
| 0 | XIII Muluc | 2 | Kankin (13 Muluc). | |
| 1) | 0-52 | XIII Imix | 14 | Pax. |
| 2) | 53-104 | XIII Ben | 1 | Pop (1 Ix). |
| 3) | 105-156 | XIII Chicchan | 13 | Zip. |
| 4) | 157-208 | XIII Caban | 5 | Xul. |
| 5) | 209-260 | XIII Muluc | 17 | Mol. |
| 6) | 261-312 | XIII Imix | 9 | Zac. |
| 7) | 313-364 | XIII Ben | 1 | Kankin. |
| 8) | 365-416 | XIII Chicchan | 13 | Pax. |
| 9) | 417-468 | XIII Caban | 25 | Cumhu. |
| 10) | 469-520 | XIII Muluc | 12 | Zip (2 Cauac). |
| 11) | 521-572 | XIII Imix | 4 | Xul. |
| 12) | 573-624 | XIII Ben | 16 | Mol. |
| 13) | 625-676 | XIII Chicchan | 8 | Zac. |
| 14) | 677-728 | XIII Caban | 20 | Mac. |
| 15) | 729-780 | XIII Muluc | 12 | Pax. |
If we adopt this arrangement for the present we cannot fail to see that the author had an aim in view, when we consider the following:—
1. The zero-point lies 15,609 days later than the normal date IV Ahau 8 Cumhu (9 Ix). This is equal to 20 × 780 or 60 × 260 increased by the interval between IV Ahau and XIII Muluc = 9. There are 86 days between 2 Kankin and 8 Cumhu i.e., 15,609 = 43 × 365 - 86, and from 9 Ix to 13 Muluc it is 43 years.
