At the right side of Dres. 72c are the three characters shown in plate LXIV, 27, 28, and 29, which follow one another downward, as shown in the figure, the three forming one of the short columns of the series to which they belong. From the lowest, which is the _ik_ symbol, waving blue lines, indicating water, extend downward to the bottom of the division. If these glyphs are considered ideographic and not phonetic, it is still possible to give them a reasonable interpretation. The falling water shows that they relate to the rain storm or tempest. The uppermost character, which appears to be falling over on its side, we may assume to be the symbol of a house or building of some kind;[215-1] the dotted lines extending from its surface may well be supposed to represent rain driven from the roof. There is, however, another possible interpretation of this character which appears to be consistent with Mexican and Central American mythology. It is that it indicates a house, vessel, or region of the heavens which holds the waters of the upper world. The turning on the side would, in this case, denote the act of pouring out the water in the form of rain. This supposition (although I am inclined to adopt the former) appears to be supported by the fact that this character is used in the Dresden Codex as one of the cloud or heaven symbols, as, for example, on plates 66 and 68. According to Ramirez, the Mexican wind and rain gods occupy a large mansion in the heavens, which is divided into four apartments, with a court in the middle. In this court stand four enormous vases of water, and an infinite number of very small slaves (the rain drops) stand ready to dip out the water from one or the other of these vases and pour it on the earth in showers.[216-1] As the lowest character in the group mentioned is the _ik_ symbol, its appropriate rendering here is beyond question "wind;" therefore, as two out of the three characters, and the rain sign below, indicate the rain storm, we may take for granted that the middle character probably refers to lightning or thunder. Additional reasons for this interpretation are given in a previous paper[216-2] and need not be repeated here, as the only object now in view in referring to them is to show that the _ik_ symbol is there used to denote wind.
