Deducting from this number all the Calendar Rounds possible, 14 (see Table [XVI]), and applying rules 1, 2, and 3 (pp. [139], [140], and [141], respectively), the terminal date reached will be 1 Ahau 13 Mac. Of this date, the day part, 1 Ahau, is recorded very clearly in A8 B8. Compare the head in A8 with the head in A3, which, we have seen, stood for 1 and also with figure [51], a-e, and the head in B8 with figure [16], h', i', the profile head for the day sign Ahau. This text is irregular in that the month glyph follows immediately the day glyph, i.e., in A9. The glyph in A9 has a coefficient 13, which agrees with the month coefficient determined by calculation, and a comparison of B9 with the forms for the months in figure [19] shows that the month Mac (fig. [19], w, x) is here recorded. The whole Initial Series therefore reads 1.18.5.4.0 1 Ahau 13 Mac.
In plate [12], B, is figured the Initial Series on the tablet from the Temple of the Sun at Palenque.[[153]] The introducing glyph appears in A1-B2 and is followed by the Initial-series number in A3-B7. The student will have no difficulty in identifying the period glyphs in B3, B4, B5, B6, and B7; and the cycle, katun, and tun coefficients in A3, A4, and A5, respectively, will be found to be exactly like the corresponding coefficients in the preceding Initial Series (pl. [12], A, A3, A4, A5), which, as we have seen, record the numbers 1, 18, and 5, respectively. The uinal coefficient in A6, however, presents a new form. Here the determining characteristic is the banded headdress, or fillet, which distinguishes the head for 3, as explained on page [98] (see fig. [51] h, i). We have then in A6 B6 record of 3
uinals. The kin coefficient in A7 is very clearly 6. Note the "hatchet eye," which, as explained on page [99], is the essential element of this head numeral, and also compare it with figure [51], t-v. The number recorded in A3-B7 therefore is 1.18.5.3.6. Reducing this to units of the first order by means of Table [XIII], we obtain:
| A3B3 = | 1 × | 144,000 = | 144,000 |
| A4B4 = | 18 × | 7,200 = | 129,600 |
| A5B5 = | 5 × | 360 = | 1,800 |
| A6B6 = | 3 × | 20 = | 60 |
| A7B7 = | 6 × | 1 = | 6 |

Deducting from this number all the Calendar Rounds possible, 14 (see Table [XVI]), and applying rules 1, 2, and 3 (pp. [139], [140], and [141]), respectively, to the remainder, the terminal date reached will be 13 Cimi 19 Ceh. If this inscription is regular, the day part of the above date should follow in A8 B8, the former expressing the coefficient and the latter the day sign. Comparing A8 with the head numerals in figures [51]-[53], it will be found to be like the second variant for 13 in figure [52], x-b', the essential element of which seems to be the pendulous nose surmounted by a curl, the protruding mouth fang, and the large bulging eye. Comparing the glyph in B8 with the day signs in figure [16], it will be seen that the form here recorded is the day sign Cimi (fig. [16], h, i). Therefore A8 B8 expresses the day 13 Cimi. The month glyph is recorded very irregularly in this text, since it occurs neither immediately after the Supplementary Series or the day sign, but the second glyph after the day sign, in B9. A comparison of this form with figure [19], u-v, shows that the month Ceh is recorded here. The coefficient is 19. Why the glyph in A9 should stand between the day and its month glyph is unknown; this case constitutes one of the many unsolved problems in the study of the Maya glyphs. This whole Initial Series reads 1.18.5.3.6 13 Cimi 19 Ceh.
The student will note that this Initial Series records a date 14 days earlier than the preceding Initial Series (pl. [12], A). That two dates should be recorded which were within 14 days of each other, and yet were more than 3,000 years earlier than practically all other Maya dates, is a puzzling problem. These two Initial Series from the Temple of the Sun and that of the Foliated Cross at Palenque, together with a Secondary-series date from the Temple of the Cross in the same city, have been thoroughly reviewed by Mr. Bowditch (1906). The conclusions he reaches and the explanation he offers to account for the occurrence of three dates so remote as these are very reasonable, and, the writer believes, will be generally accepted by Maya students.
