The other Secondary Series on this monument (see fig. 79, _B_) appears at B1-A2, and records 18 tuns, 3 uinals, and 14 kins, which we may write thus: 18.3.14. As in the preceding case, the date following this number in B2-A3 is its starting point, not its terminal date, a very unusual feature, as has been explained. This date is 6 Cimi 4 Tzec--compare B2 with the sign for Cimi in figure 16, _h, i_, and A3 with the sign for Tzec in figure 19, _g, h_--and as far as Stela J is concerned it is not fixed in the Long Count. However, elsewhere at Quirigua this date is recorded in a Secondary Series, which is referred back to an Initial Series, and from this passage its corresponding Initial Series is found to be 9.15.6.14.6 6 Cimi 4 Tzec. Reducing the number recorded in B1-A2, 18.3.14, to units of the first order, we have: A2 = 18 × 360 = 6,480 B2 = 3 × 20 = 60 B2 = 14 × 1 = 14 ----- 6,554 Applying rules 1, 2, and 3 (pp. 139, 140, and 141, respectively) to the number, the terminal date reached will be 8 Ahau 8 Zotz, which does not appear in figure 79, _B_. The Initial Series corresponding to this date may be calculated as follows: 9.15. 6.14. 6 6 Cimi 4 Tzec 18. 3.14 9.16. 5. 0. 0 8 Ahau 8 Zotz But this was the Initial Series recorded on the reverse of this monument, consequently the Secondary-series dates, both of which have {218} preceded the Initial-series date in point of time, bring this count up to the contemporaneous time of this monument, which was 9.16.5.0.0 8 Ahau 8 Zotz. In view of the fact that the Secondary Series on Stela J are both earlier than the Initial Series, the chronological sequence of the several dates is better preserved by regarding the Initial Series as being at the close of the inscription instead of at the beginning, thus: 9.14.13. 4.17 12 Caban 5 Kayab Figure 79, _A_, B3-A4 0.11.13. 3 B1-B2 [9.15. 5. 0. 0] [10 Ahau 8 Chen][196] [1.14. 6][197] 9.15. 6.14. 6 6 Cimi 4 Tzec Figure 79, _B_, B2-A3 18. 3.14 B1-A2 9.16. 5. 0. 0 8 Ahau 8 Zotz Figure 78, A1-B9, B13 By the above arrangement all the dates present in the text lead up to 9.16.5.0.0 8 Ahau 8 Zotz as the most important date, because it alone records the particular hotun-ending which Stela J marks. The importance of this date over the others is further emphasized by the fact that it alone appears as an Initial Series. The text of Stela J illustrates two points in connection with Secondary Series which the student will do well to bear in mind: (1) The starting points of Secondary-series numbers do not always precede the numbers counted from them, and (2) the terminal dates and starting points are not always both recorded. The former point will be illustrated in the following example:
