" The left column on each page I have restored,
although no traces of it are left. But apart from its manifest
necessity, as part of the series, if the width of the red ground on page
20 (see the photographs) is measured, it will be found to be just the
correct proportion, and part of the straight left edge of the red can
still be seen, just left of the rod in the hand of the mummy-figure, and
leaving just room for the Ezanab column. In the colored plates I have
only shown 12 instead of 13 day-signs in each column, but a measurement
of the space above and below shows that the missing four are to be
placed at the top and not at the bottom. These two pages therefore have
application in some way to 52 solar years, beginning with 1 Lamat and
ending with 13 Akbal (Votan).

These "year-bearers" are those of the Tzental instead of the Yucatecan
system, as described by Landa, and on these two pages rests, so far as
regards known subject-matter, the assignment of the Codex Perez to the
Palenque rather than to the northern Maya district. It is thus to be
considered with the Inscriptions of that region, and with the Dresden
Codex.[28-*] And in accord with what is known of the state of the
different parts of the country at the time of the Conquest, and of the
history of the break-up and extinction of the Maya empire, it must be
assigned the greater antiquity on that account.

It is probable that pages 19 and 20 had no text passages.

Pages 21 and 22 again, judging from the coloring and the arrangement,
seem to form a pair. Each had on the upper part probably five rows of
glyphs, some 70 in all, of which only 10 or 12 are at all recognizable.
Contrary to all the pages hitherto discussed, it may be that these
glyphs are to be _read from right to left_. The faces in these all look
to the right, and the customary prefixes are all on the right. In
classifying these glyphs, therefore, they must be all reversed.

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
Anci
