THE NEPHRITE STONE OF THE LEYDEN MUSEUM 



Reference is made to the insci-iption on this stone (figure 170), 



wliich has been frequently noticed lieretofore, merely to show the date 



from wiiicli the initial series is counted. The series is as follows, 



omitting the great cycle: 8-14-3-1-12, 1 Eb 5 



. — I ini// — o (month). The month symbol, though distinct, 



Qi/yy^^MTX'^^ '^ unusual, in fact unique, unless it includes 



the "kin" glyph immediately below, which is 



very proliable; in this case it is most like the 



Ya.xkin symbol. Reducing the series to days 



and subtracting 66 calendar rcninds, we have 



the following result:

Total 1, 253, 913

Counting forward 1,232 days fi'om 4 Ahau 8 

 t'umliu, tlie first day of Goodman's 54tli great 

 cycle, Seler's "normal date," we reach 4 Ix 10 

 Xul. This is wrong; but by counting forward 

 from 4 Ahau 8 Zotz, the first day of Goodman's 

 53rd great cycle, we reach 1 El) 5 Zac, which 

 agrees with the inscription so far as the day 

 anil day number and the day of the month 

 l) f j^^~T\nM\ ' I '^'^ concerned, liut still leaves the doubt as to 

 -^ ^ ^ ' the month. Tli is result also agrees with Good- 



man's tables and his interpretation of this 

 series (page 148). Assuming it to be correct, 

 we find the terminal date to be 618,088 days 

 back of or anterior to the "normal date," 4 

 Ahau 8 Cumhu ; and the commencement of the 

 10th (Goodman's 9th) cycle of the 54th great 

 cycle stand.s 1,296,000 days after this normal 

 date; hence the time of inscribing the series 

 on the nephrite stone (assuming the terminal 

 date to indicate this time) was 5,244 years an- 

 terior to the beginning of the 10th cycle, the 

 anterior limit fixed by Seler for the date of 

 the inscriptions. However, it must be remembered that this calcula- 

 tion is based on the theory that the series on this stone falls in one of 

 the three great cycles tabulated by Goodman. This theory, as is
