Dr Seler also refers in this connection to the lower line of symbols on Dres. 29-30b (three of which are shown in plate LXVIII, 15, 16, 17); to those shown in plate LXVIII, 18, 19, from Tro. 14c; and those shown in plate LXVIII, 20, 21, from Tro. 11a. He remarks that "in a number of hieroglyphs the character _imix_ stands as an equivalent of a peculiar animal head which bears as a distinctive mark the element _akbal_ over the eye. Thus in the hieroglyphs enumerating those above mentioned which, standing after the hieroglyphs of the cardinal points, seem to express the deities presiding over them, indeed there appears here on the same animal head, on one hand the character _imix_, on the other the element figure 165" (our plate LXIV, 5). Although I am unable to interpret satisfactorily the _imix_ symbols in the places above referred to, I think it can be made apparent that Dr Seler's explanation is without foundation. For instance, by referring to the plates of the Dresden and Troano codices mentioned, it will be seen that there is nothing whatever that refers to an "animal head which bears the element _akbal_ over the eye," unless we suppose it to be in plate LXVIII, 16 (from Dres. 29b) and LXVIII, 21 (from Tro. 11a). There is no figure below or connected with either series to justify this conclusion. It is also certain that plate LXVIII, 21 (Tro. 11a) is not an animal head. Possibly plate LXVIII, 16 (Dres. 29b) may be intended for an animal head, but this is not certain and, moreover, it is not repeated in the series. Referring to Cort. 27a it will be seen that the compound glyph shown in plate LXVIII, 22 (apparently the same as that on Tro. 11a) is repeated four times in one line, each connected with a cardinal point symbol, and each standing immediately over and evidently referring to a large vessel.[209-1] It is stated that it was a custom among the Maya during certain religious ceremonies to place a vessel in their temples at each of the four cardinal points.[209-2] As _cum_ and _xamach_ are Maya words signifying vessel, we still find in these the _m_ sound. It is therefore possible that the similar glyphs on Dres. 29b and Tro. 14 and 15 also refer to vessels. The supposition seems to be strengthened by the fact that connected with the former are figures of the four classes of food animals--quadrupeds, birds, reptiles (iguana), and fishes. The latter refer to the hunter's occupation, being accompanied by figures of the deer. Landa, in his descriptions of the various festivals, repeatedly alludes to the four Chacs or Bacabs which represent the four cardinal points, and to the different classes of food animals presented where vessels were used. It is therefore more likely that the symbol is used in the places mentioned because of its phonetic value rather than as a substitute for the heads of lightning animals, for which supposed substitution Dr Seler admits he can not account.
