THOMAS] TABLET OF THE CROSS (ASC 
that it can not be determined (except the numerals) with positive cer- 
tainty; itappears to be 5 Ahau 3 Tzec. Glyphs V12, U13 give another 
date, 5 —? 20 Zotz. The features of the day symbol are completely 
obliterated; the prefix to the month glyph is the symbol for 20. Imme- 
diately following, at V13 V14, is the series (6) 16 days, 6 chuens, 19 
ahaus, 1 katun (14,176 days); at U17, V17 the date 5 Kan 12 Kayab; at 
W1, W2 the series (7) 17 days, + chuens, 2 ahaus, 2 katuns (15,217 days); 
at X5, W6 the date 1 Imix 4+ Ceh (or Zip), month symbol somewhat 
doubtful, but one of the two named, apparently Ceh. Following this 
at X6, W7 is the brief series (8) 1 day, 1 chuen, 1 ahau (881 days), fol- 
lowed at X10, W11 by the date 7 Kan 17 Mol; this is followed at 
X11, X12 by the series (9) 7 days, + chuens, 8 ahaus, 2 katuns (17,367 
days); following this at W14, X14 is an uncertain date—11 Cib, Cimi, 
or Chicchan, 14/ (or 184) Kayab? The day symboland its number are 
distinct and clear, but the symbol is unusual; the number prefixed to 
the month symbol has been partially broken away; there were cer- 
tainly two lines (10) and some two, three, or four balls. The month 
symbol is uncertain, but is apparently the same as that of the date 13 
Ahau 18 Kayab? or Xul, in column L, though it has something addi- 
tional on top. It is possible the symbol is intended for Chen or 
Kankin. ; 
Following the last date (11 Cib?) at W15, X15 is the series (10) 2 days, 
8 chuens, 16, 17, 18, or 19 ahaus. The three lines (15) prefixed to the 
ahau symbol are distinct, but the additional balls or dots haye been 
injured to such an extent as to render the number uncertain (7,002 
days, counting 19 ahaus). There is no date or other series in the 
remaining portion of the inscription. 
If it be possible to determine the plan, succession, or arrangement 
of the series in this inscription, an important step will have been 
gained and a basis laid for the correct determination of the associated 
glyphs. The peculiarities of Mayan time system and notation so 
often lead to deceptive results that extreme caution is required, and a 
single connection or proper result is seldom sufficient evidence of a 
correct interpretation. 
Taking the list of the series as given we are at once impressed with 
the strong general resemblance to the plan of the series on many of the 
plates of the Dresden codex, where several different series are found, 
some reckoned in one direction and some in another, as, for example, 
plate 73, where there are one entire series, parts of two others, and 
dislocated parts of two; or plate 70, where there are, in whole or in 
part, some half dozen series still in a tangle which has not yet been 
straightened out; also other plates. 
Taking merely the numerical series in the order they stand and 
changed to days, there is certainly in the irregularly ascending scale 
an indication of arrangement, of and relation between the series.
