On the other hand, there are many things, which favor an entirely different interpretation of these hieroglyphs. Thus I am of the opinion that the ritual year of 364 days with its four Bacab periods of 91 days each is referred to here, as we have already found it referred to on pages 31a-32a and on page 45a, and shall find it again on pages 65-69 and 71-73. In that case the single groups would be separated from one another by one Maya week = 13 days. I will now arrange the sixty-nine groups in the following order (the reason for which will become clear directly):-- I 4 11 18 25 32 39 46 53 60 67 II 5 12 19 26 33 40 47 54 61 68 III 6 13 20 27 34 41 48 55 62 69 IV 7 14 21 28 35 42 49 56 63 1 V 8 15 22 29 36 43 50 57 64 2 VI 9 16 23 30 37 44 51 58 65 3 VII 10 17 24 31 38 45 52 59 66. The groups in a horizontal row are separated from one another by 7 or a multiple of 7. If now a hieroglyph is repeated in those places, which are in the same horizontal row, then this is a confirmation of the supposition that Bacab periods are meant to be represented here. Hence I will examine each row in turn. These rows extend over the long period of 69 × 13 days probably merely for the purpose of filling up the space. I. In 39b, 46b, 53b and 60b, _i.e._, after every seven groups, perhaps also in 18b, we find the following sign, which I identified as that of a Bacab, in Globus, Vol. LXXI:-- [Illustration] Hence this denotes the beginning of the Bacab period. In 4b the sign is replaced by that for Venus. In 11b, 25b, 32b and 67b we find other signs, it is true, nevertheless the regularity stated above cannot be accidental. The upper signs of groups 39a, 46a, 53a and 60a contain an Imix and corroborate the connection. II. 5b and 26b (after 3 × 91 days) contain a head very like the preceding, which readily suggests the idea that it is merely a Bacab sign pushed one group ahead, but it also appears in 13b, 50b and 52b. Then 12b, 54b and 61b correspond, _i.e._, after six groups of 91 days and one more of the same length, but the same sign appears also in 34b, 48b and 56b. III. 41b and 69a are Xul = end and are therefore separated by 28 × 13 = 4 × 91 days, _i.e._, the length of a year. It is singular that both signs of 41 are like those of 47; if we assume that 47 was set down one group too soon, it would be in excellent keeping with the rest. The Xul also appears in 11b and 28b. 34b and 48b correspond after 2 × 91 days, as already mentioned under II. IV. 42a and 49b both contain the sign for the sun between clouds. V. 36b and 57b agree after 3 × 91 days; the same sign appears again in 10b and 20b. 15a and 36a correspond after 3 × 91 days; we shall continue the examination of this sign under pages 71-73.
