INITIAL SERIES (A) AND SECONDARY SERIES (B) ON STELA F (WEST SIDE), QUIRIGUA

Passing over B6-A10, the meanings of which are unknown, we reach in B10 the Secondary-series number 13.9.9. Reducing this to units of the first order, we have:

B10b = 13 × 360 = 4,680
B10a = 9 × 20 = 180
B10a = 9 × 1 = 9
——
4,869

Assuming that our starting point is the date next preceding this number in the text, that is, the Initial-series terminal date 12 Caban 5 Kayab in B5-A6, and applying rules 1, 2, and 3 (pp. [139], [140], and [141], respectively), the terminal day reached will be 6 Cimi 4 Tzec. This date the student will find recorded in plate [19], B, B11b-A12a. Compare B11b with the sign for Cimi in figure [16], h, i, and A12a with the sign for Tzec in figure [19], g, h. Moreover, since the Initial-series value of the starting point 12 Caban 5 Kayab is known, the Initial-series value of the terminal date 6 Cimi 4 Tzec may be calculated from it:

9.14.13. 4.17] 12 Caban 5 Kayab
13. 9. 9]
9.15. 6.14. 6] 06 Cimi 4 Tzec[[200]]

In A15 is recorded the date 3 Ahau 3 Mol (compare A15a with fig. [16], k', i', and A15b with fig. [19], m, n) and in A17 the date 4 Ahau 13 Yax (compare A17a with fig. [16], e'-g' and A17b with fig. [19], q, r). This latter date, 4 Ahau 13 Yax, is recorded elsewhere at Quirigua in a Secondary Series attached to an Initial Series, where it has the Initial-series value 9.15.0.0.0. This value we may assume, therefore, belongs to it in the present case, giving us the full date 9.15.0.0.0 4 Ahau 13 Yax. For the present let us pass over the first of these two dates, namely, 3 Ahau 3 Mol, the Initial Series of which as well as the reason for its record here will better appear later.

In B17-A18a is recorded another Secondary-series number composed of 3 kins, 13 uinals, 16 tuns, and 1 katun, which we may write thus: 1.16.13.3. The student will note that the katun coefficient in A18a is expressed by an unusual form, the thumb. As explained on page [103], this has a numerical value of 1. Again, our text presents another irregular feature. Instead of being counted either forward or backward from the date next preceding it in the text; that is, 4 Ahau 13 Yax in A17, this number is counted from the date following it in the text, like the two Secondary-series numbers in Stela J, just discussed. This starting date recorded in A18b B18a is 12 Caban 5 Kayab, which, as we have seen, is also the date recorded by the Initial Series in plate [19], A, A1-A6. We are perfectly justified in

assuming, therefore, that the 12 Caban 5 Kayab in A18b-B18a had the same Initial-series value as the 12 Caban 5 Kayab in plate [19], A, B5-A6, namely, 9.14.13.4.17. Reducing the number in B17-A18a, namely, 1.16.13.3, to units of the first order, we have:

A18a = 1 × 7,200 = 7,200
B17b = 16 × 360 = 5,760
B17a = 13 × 20 = 260
B17a = 3 × 1 = 3
