2. Pictures 2, 7, 12 and 17. In the first three the god is seated on astronomical signs and in the fourth on the Moan head, which I think refers to the Pleiades. 3. Pictures 3, 8, 13 and 18. Here in the last two B is sitting _beneath_ astronomical signs. In all four pictures water, clouds and rain are represented. 4. Pictures 4, 9, 14 and 19. In the first and fourth the god is seated on D's head and on his own, and in the third on the elongated head _q_. 5. Pictures 5, 10, 15 and 20. Like the third of these five classes, these pictures are likewise distinguished by water, clouds and rain. Now the first set of pictures is between the week days XIII and IX, the second between IX and VII, the third between VII and I, the fourth between I and XI, the fifth between XI and XIII, while the month days are quite different. Hence the conjecture is but natural that the pictures and week days bear some relation to one another, though that relation is still shrouded in obscurity. Pages 40c--41c.

In the groups of four hieroglyphs each, which belong to each of the six parts, the sign _f_ always occupies the first place, and B the third. Let us now examine the six parts separately. 1. B is sitting in a boat and rowing (as on the top of the same page). Around his head there is again the suggestion of what may denote the starry sky, and in this picture his nose-peg is unusually large. The second sign is an Imix, but it might also denote the thirteenth month Mac and therefore the Tonalamatl (13 × 20). The fourth sign is a fish forming a connecting link between the water represented below and the rest of the group. 2. B is seated on the Caban sign and his arms are apparently resting on an altar standing in front of him, on which fire is burning, indicated by the Ik sign, while the moon is placed below the altar. The Caban sign below is repeated in the second hieroglyph, combined here as usual with a sign which may be Muluc. The fourth sign is a head. I think the scribe meant to set down an 8 before it, but as there was not sufficient space for the heavy line _after_ the three small circles, he indicated it by a black dot _below_ the circles. Now, if we call the head D's, which of course cannot be asserted positively, this would be day VIII Ahau, and this, in fact, is twenty days from the beginning day I Ahau, as it is meant to be in this passage. There is no representation of food; can this have been a fast day? 3. B is seated on four astronomical signs. He wears the gala mantle and holds a serpent in his hand.
