The first tonalamatl figured from the Codex Tro-Cortesianus (see pl. 29) extends across the middle part of two pages (Tro-Cor. 10b, 11b). The four day signs at the left indicate that it is divided into four divisions, of which the first begins with the day 13 Ik.[248] Adding to this the first black number 9, the day 9 Chuen is reached, and proceeding in this manner the tonalamatl may be outlined as follows: [Illustration: MIDDLE DIVISIONS OF PAGES 10 AND 11 OF THE CODEX TRO-CORTESIANO, SHOWING ONE TONALAMATL EXTENDING ACROSS THE TWO PAGES] [Illustration: PAGE 102 OF THE CODEX TRO-CORTESIANO, SHOWING TONALAMATLS IN THE LOWER THREE SECTIONS] {263} ---------------------+----------+----------+----------+---------- |1st |2d |3d |4th |Division |Division |Division |Division ---------------------+----------+------- --+----------+---------- 1st part, 9 days, | | | | beginning with day |13 Ik |13 Manik |13 Eb |13 Caban | | | | 2d part, 9 days, | | | | beginning with day |9 Chuen |9 Cib |9 Imix |9 Cimi | | | | 3d part, 10 days, | | | | beginning with day |5 Ahau |5 Chicchan|5 Oc |5 Men | | | | 4th part, 6 days, | | | | beginning with day |2 Oc |2 Men |2 Ahau |2 Chicchan | | | | 5th part, 2 days, | | | | beginning with day |8 Cib |8 Imix |8 Cimi |8 Chuen | | | | 6th part, 10 days, | | | | beginning with day |10 Eznab |10 Akbal |10 Lamat |10 Ben | | | | 7th part, 5 days, | | | | beginning with day |7 Lamat |7 Ben |7 Eznab |7 Akbal | | | | 8th part, 7 days, | | | | beginning with day |12 Ben |12 Eznab |12 Akbal |12 Lamat | | | | 9th part, 7 days, |6 Ahau |6 Chicchan|6 Oc |6 Men beginning with day |[249] |[249] |[249] |[249] | | | | Total number of days |65 |65 |65 |65 ---------------------+----------+----------+----------+---------- Applying rule 4 (p. 253) to this tonalamatl, we have: 4 × 65 = 260, the exact number of days in a tonalamatl.
