166 THE INSCRIPTIONS AT COPAN. 
a range of about 360 years, was 9.11.15.0.0 4 Ahau 13 Mol, the next earlier 
occurrence being in 8.13.10.0.0, and the next later in 10.10.0.0.0, both 
impossible dates, so far as Copan is concerned, and both impossible here 
because the hotun-sign and not the lahuntun-sign is recorded. And finally, 
the record of the day 12 Ahau just after this in Ka may record the preceding 
katun-ending, 7. ¢., 9.11.0.0.0 12 Ahau 8 Ceh. Indeed, there is little doubt 
that 9.11.15.0.0 was the hotun recorded by this Initial Series, in spite of the 
irregularity of the tun coefficient, and the loss of the kin and day-signs. 
Let us turn again to our Initial Series, and see how these values for the 
katun, tun, and uinal coefficients agree with those actually recorded on 
Fragment V (plate 20, b). The uinal coefficient in cb u. h. is surely 0, which 
agrees with the value for the corresponding coefficient obtained above. 
The katun  coeffi- (7 cient (Bb u. h.) should be 11; unfortunately 
only two other occur- ~~ (: rences of the head for 11 are known, namely, 
the katun coefficient on | Lintel 2 at Piedras Negras and the katun 
coefficient on Stela6 at Yaxchilan YD. Although there ($ € appears to be 
no element common to both of (% these signs, both nevertheless 
are of the same type, namely, the normal human head, and to this 
extent the head in Bb u. h. may be said to resemble them. 
The tun coefficient (ca u. h.) is composed of a head variant, clearly 
the death’s head, denoting 10, preceded by a bar, possibly denoting 
5, as already suggested. If we may join these two elements by addition, 
1. €., 1O+5=15, forming a-composite numeral, we will have the tun coeffi- 
cient demanded by the corresponding Initial Series terminal date. Butsucha 
combination, 7. ¢., a bar-and-dot numeral joined with a head-variant num- 
eral, is a new feature in Maya notation, and before it can be accepted, even 
in the face of the very strong evidence presented by the hotun-ending date 
in 1bj, it is necessary to adduce other examples of its occurrence. Fortun- 
ately several such may be cited. ‘The customary way to have expressed the 
number 15 would have been either by 3 bars or, since all the other 
coefficients in this text are head-variant num- erals, by the head for 
10 + the head for 5 FAQe). Neither, however, IU was employed in the 
present instance, r=10 but instead a combination of the two seems to 
have been used. Fb 
One other instance of this kind has already been noted, namely, the tun 
coefficient of the Initial Serieson Stelar2. (See plate 17, a4, and pp. 135, 136.) 
Unfortunately this example is doubtful, since the numerical bar inclosed in 
an oval above the death’s head is partially effaced. If it is a bar at all, 
however, the parallel is complete between these two cases, both being tun 
coefficients in Initial Series and both expressing the same number, 15, in the 
same unusual way—a bar joined to a death’s head. 
Other examples, not in Initial Series, however, may be cited. The 
first and most striking of these is in the Supplementary Series from the 
Temple of the Cross at Palenque, but in order to bring this point out, it is
