he glyphs, face-tun glyphs
and also others, on these two pages with those on pages 2 to 11, already
discussed, the possibility that a katun-series is a part of this
subject-matter must be considered.

On the other hand, the glyphs in the upper part of all four pages 21 to
24 face to the right, and, as already set out in detail, are practically
all written in _reverse position_ as regards their prefixes, etc. And so
also does the Eb-glyph in the day-columns we are now considering face to
the right. These columns, unlike those on page 21, which include all of
the 20 day-signs, only include 5 of the day-signs: Kan, Lamat, Eb, Cib
and Ahau; Eb being the only non-symmetrical one of these.

We have thus quite strong evidence, especially as provided by the
position of the prefixes, for a right to left reading, opposed by the
direction of this katun-number series--if it be one. In Egyptian
writing, of course, the direction of the reading changes with the facing
of the figures.

To return now to the columns themselves, all the day-signs in any one
column have each the same red numeral, so that we have: 8 Cib, 8 Ahau, 8
Kan, 8 Lamat, 8 Eb; and so on. The red numerals to each column also
decrease by 2 towards the right, pari passu with the blue numerals. If
we read each column downwards, it will form a closed circuit or round,
returning into itself, with intervals of 104 days, from 8 Cib to 8 Ahau,
etc., and again from 8 Eb back to 8 Cib. But if we next try to go to the
next column, the series breaks, for from 8 Eb to 6 Lamat is only 76
days. We get a like break whether we read upward or downward, or right
to left. Taking the columns separately then, the entire series (whether
made up of 13, 20 or any other number of columns) cannot be made to read
in one regular series, with a constant interval between the successive
days of the whole.

But, if we restore two columns, making 13 columns, and then read
horizontally _across_, either right to left, or left to right, one line
after another, the first day of the second line follows the last of the
first, and after going through the whole 65 terms, we return again from
the last of the last line to the first of the first--always with a
constant interval. In other words, this section could be written around
a wheel. If we read left to right, the distance from (10 Kan) to 8 Cib,
etc., is 232 days; 232x65=15,080. Or if from right to left,[33-*] the
interval from (12 Lamat) to 1 Cib, etc
