It is possible, and perhaps probable, as stated above, that the Maya symbol of this day was taken originally from the conventional method of representing the female breast. Drs Seler and Schellhas appear to be of this opinion. But it does not necessarily follow from this that the character used for the name of the day has any reference to the female breast, as it is more likely used in this relation for its phonetic value alone, _m_ being the chief phonetic element indicated thereby. If the supposition herein advanced that the combination shown in plate LXIV, 9, denotes bread or food be correct, it is possible that the symbol is also sometimes used to indicate "maize," _ixim_ or _xim_, on account of its phonetic value. As will be shown farther on, the _kan_ symbol is not only used to denote the grain of maize and maize in the general sense, but it appears to denote in some cases bread or the tortilla. THE SECOND DAY Maya, _ik_; Tzental, _igh_; Quiche-Cakchiquel, _ik'_; Zapotec, _gui_, _ni_, _laa_, _laala_ or _liaa_; Nahuatl, _ehecatl_. The form of the symbol of this day presents a number of minor variations, the more important of which are shown in plate LXIV, 18-26. Symbol 18 is the form given by Landa; 19-24, those found in the codices; 25 is from the left slab of the Palenque tablet or altar plate, and 26 is from the Tikal inscription. So far as this character can satisfactorily be interpreted, where used otherwise than as a day symbol, the signification appears to be wind, spirit, or life, whether considered phonetic or not. As illustrations of its use, the following examples are presented:
