ve comprised 24, the other 15 leaves. But
Aglio copied each of the two pieces in such way as to trace first the
whole of one side and then the other of the entire piece, always
progressing from left to right, in European style. Therefore Aglio's
model was as follows:

"_First piece_:

"Front (from left to right): 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,
14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.

"Back (from right to left): 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35,
34, 33, 32, 31, 30, 0, 0, 0, 28, 27, 26, 25.

"_Second piece_:

"Front (from left to right): 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56,
57, 58, 59, 60.

"Back (from right to left): 74, 73, 72, 71, 70, 69, 68, 67, 66, 65, 64,
63, 62, 61, 0.

"In considering this, our attention is attracted by the position of the
four blank pages, three of which are together, the fourth alone. It might
be expected that the separate blank page began or concluded the second
piece and was purposely left blank, because in the folding of the whole
it would have lain outside and thus been exposed to injury; the other
three would be expected at the end of the first piece. The former, as is
easily seen, was quite possible, but the latter was not, unless we assume
that even at the time Aglio took his copy the original order had been
entirely disturbed by cutting and stitching together again. The four
blank pages show no trace of ever having contained writing; the red brown
spots which appear on them are to be found also on the sides that contain
writing. Perhaps, therefore, those three continuous pages indicate a
section in the representation; perhaps it was intended to fill them later
on; in a similar way also page three has been left unfinished, because
the lower half was only _begun_ by the writer.

"I do not wish to conceal my view that the two pieces which Aglio found
were separated from the beginning; that they belong even to two different
manuscripts, though written in the same form; but, since it is human to
err, I will here and there follow custom in the succeeding pages in
speaking of one codex.

"My conviction rests especially on the fact that the writer of manuscript
A (pp. 1-45) endeavors to divide each page by two horizontal lines into
three parts, which the writer of manuscript B (pp. 46-74) rarely does.
The more precise statement is as follows: In A, pp. 1-23 and 29-43 always
show two such lines in red color; pp. 25-28 have no red lines, but
clearly sho
