J. Walter Fewkes has made god D the subject of a special, very detailed monograph (The God "D" in the Codex Cortesianus, Washington, 1895) in which he has treated also of gods B and G, whom he considers allied to D. He believes D to be the god Itzamna, as do also Foerstemann, Cyrus Thomas and Seler, and sees sun-gods in all three of these deities. Whether god D is to be separated from G and B as an independent deity, Fewkes thinks is doubtful. Brinton again holds that god D is Kukulcan. These different opinions show, at all events, on what uncertain grounds such attempts at interpretation stand, and that it is best to be satisfied with designating the deities by letters and collecting material for their purely descriptive designation. According to Foerstemann the calendar day devoted to D is Ahau. E. The Maize-God. [Illustration: Figs. 21-27] This god bears on his head the Kan-sign and above it the ear of maize with leaves (Fig. 23); compare Dr. 9b (left figure), 11b, 12a, etc. The hieroglyph is definitely determined (Fig. 21). The god is identical with the figures recurring with especial frequency in the Madrid manuscript, the heads of which are prolonged upward and curved backward in a peculiar manner; compare Cort. 15a, 20c, 40 (bottom), Tro. 32*b (Figs. 25-27) and especially the representation in Dr. 50a (Fig. 24), which is very distinct. This head was evolved out of the conventional drawing of the ear of maize; compare the pictures of the maize plant in the Codex Tro., p. 29b (Fig. 22) with the head ornament of the god in Dr. 9b (Fig. 23), 9a, 12a; what was originally a head ornament finally passed into the form of the head itself, so that the latter appears now as an ear of maize surrounded by leaves. Compare the pictures, Figs. 25-27. That these gods with elongated heads are, in point of fact, identical with E is plainly seen from the passage in Dr. 2 (45)c (first figure). There the figure represented, which is exactly like the pictures in the Madrid manuscript, is designated explicitly as god E by the third hieroglyph in the accompanying writing. The hieroglyph of this deity is thus explained; it is the head of the god merged into the conventionalized form of the ear of maize surrounded by leaves. When we remember that the Maya nations practised the custom of artificially deforming the skull, as is seen in particular on the reliefs at Palenque, we may also regard the heads of these deities as representations of such artificially flattened skulls. God E occurs frequently as the god of husbandry, especially in the Madrid manuscript, which devotes much attention to agriculture. He seems to be a counterpart of the Mexican maize-god Centeotl. The passages in the Madrid manuscript (Tro. 29a and Cort. 39a, 40a) are very remarkable, where the deity E is represented in the position of a woman in labor with numerals on the abdomen; perhaps the underlying idea is that of fruitfulness.
