consisting
throughout of 360 days. There is, in fact, nothing here indicating the
four year series as given in the authorities and as represented in our
calendar table; yet this ought to appear wherever a series extends over
more than one year.

Dr. Foerstemann says that this entire series of black numerals covers
2,920 days, or 8 years of 365 days. This is true, but the concluding
figures show that it is given by the writer of the codex as 8 years and 2
months, which would also be 2,920 days, counting the years at 360 days
each and the months 20 days each; moreover, the members of the series are
based throughout upon the year of 360 days. His theory that the intervals
of the series relate to the movements of the planet Venus is, as yet, a
mere hypothesis, which needs further proof before it can demand
acceptance; but his discovery of the methods of identifying the month
symbols on the five plates now under consideration is important. Although
I had noticed that most of the characters which he mentions are month
symbols, I did not succeed in identifying all of them.

According to his conclusion, which appears to be justified not only by
the evidence he gives but by an additional fact that I shall, presently
mention, there are four of these symbols in the upper row of the middle
group of written characters on each plate and four in the upper and lower
lines of the lower group on each plate (see, for example, Fig. 362). Each
of these symbols (except three or four) has a black number attached to it
which denotes the day of the month represented by the symbol.

These months and days as given by Dr. Foerstemann are as follows, the
positions of the lines as here given corresponding with those of the
plates:
