With the above date closes the known part of this text, the remaining glyphs, G10-G12, being of unknown meaning. Assembling all the glyphs deciphered above, the known part of this text reads as follows: 9.12. 2. 0.16 A1-A7, C2 5 Cib 14 Yaxkin 12. 9.15 D2 E2 9.12. 14. 10.11 F1 G1 9 Chuen 9 Kankin 5 F3 9.12. 14. 10.16 G3 G4 1 Cib 14 Kankin 1. 0.[189] 2. 5 G6 G7 9.13. 14. 13. 1 G8 G9 5 Imix 19 Zac [Illustration: INITIAL SERIES (_A_) AND SECONDARY SERIES (_B_) ON STELA K, QUIRIGUA] {213} We have recorded here four different dates, of which the last, 9.13.14.13.1 5 Imix 19 Zac, probably represents the actual date, or very near thereto, of this monument.[190] The period covered between the first and last of these dates is about 32 years, within the range of a single lifetime or, indeed, of the tenure of some important office by a single individual. The unknown glyphs again probably set forth the nature of the events which occurred on the dates recorded. In the two preceding texts the Secondary Series given are regular in every way. Not only was the count forward each time, but it also started in every case from the date immediately preceding the number counted. This regularity, however, is far from universal in Secondary-series texts, and the following examples comprise some of the more common departures from the usual practice. In plate 18 is figured the Initial Series from Stela K at Quirigua.[191] The text opens on the north side of this monument (see pl. 18, _A_) with the introducing glyph in A1-B2. This is followed by the Initial-series number 9.18.15.0.0 in A3-B4, which leads to the terminal date 3 Ahau 3 Yax. The day part of this date the student will find recorded in its regular position, A5a. Passing over A5b and B5, the meanings of which are unknown, we reach in A6 a Secondary-series number composed very clearly of 10 uinals and 10 kins (10.10), which reduces to the following number of units of the first order: A6 = 10 × 20 = 200 A6 = 10 × 1 = 10 --- 210 The first assumption is that this number is counted forward from the terminal date of the Initial Series, 3 Ahau 3 Yax, and performing the operations indicated in rules 1, 2, and 3 (pp. 139, 140, and 141, respectively) the terminal date reached will be 5 Oc 8 Uo. Now, although the day sign in B6b is clearly Oc (see fig. 16, _o-q_), its coefficient is very clearly 1, not 5, and, moreover, the month in A7a is unmistakably 18 Kayab (see fig. 19, _d'-f'_). Here then instead of finding the date determined by calculation, 5 Oc 8 Uo, the date recorded is 1 Oc 18 Kayab, and consequently there is some departure from the practices heretofore encountered.
