The greater part of page 21 is framed in and divided up by green bands, evidently for water, two branches of which, after crossing a constellation band near the bottom, end one in falling torrents, the other in a circle surrounding a _kin_-sign, [Hieroglyph], the sun, and itself surrounded by four dragon’s heads, all figured in the midst of the torrents. Below this symbol is the open mouth of a dragon, towards which is looking and pointing a black-faced figure, of the god D, the Ancient of Days, described by Schellhas as the moon and night god. To the left of the torrents is a figure, nearly erased, but with the wristlets characteristic of the god of death, and holding in the hand a torch. The glyph [Hieroglyph] occurs written in the torrents, at the left side. The green bands divide the middle of the page into six compartments containing, so far as not totally erased, 65 day-signs, in columns of five. All my efforts to relate these signs either to each other or to any other series in the codices, have so far been fruitless. The upper seven columns have each a black numeral beneath, running from right to left, 1 2 3 3 5 6 and the dot of another 6. Each of the columns of five day-signs forms a closed circuit returning into itself. In the upper row the 1st and 6th columns show successive days 8 apart in order; columns 2, 3, 4, 5 and 7 are 16 apart in order. The 1st in the lower row is at intervals of 8, the 2nd and 5th at intervals of 16. The 3rd column is, with the 4th, an exception, the intervals being successively 8, 4, 4, 8, 16. That this is probably not a scribal error is shown by the fact that the same series, though beginning with different days, occurs in both columns. The 6th and possible 7th columns of the lower part are indeterminable. We thus have three rounds of 5 times 8, or 40 days; seven rounds of 5 times 16, or 80 days; two irregular rounds of 40 days. These are not such columns as could form the beginning of a series of tonalamatl fifths, in which the successive days come 12 apart. So that this section must be left unexplained.[29-*] At the right of page 21 begins a solid red background which probably extended right across page 22. Two standing spotted green figures appear on page 21; seven seated figures, one green spotted, on page 22. Page 22 is crossed by a winding dragon whose body is covered by the “constellation band.” A narrow green band also winds across the page, inclosing two of the upper figures. Below the dragon and this green band are seen, seated above the open mouths of two erect dragons, two figures in conversation, each bearing various insignia of the death god. A very curious cartouche outline, partly erased, at the lower right, incloses what seems to be 13 Ahau, 3, 6, the right hand dot of the 3 being erased. * * * * *
