The worship of a goddess with virtues so natural and with powers that it was so desirable to propitiate would, in any case, it may be thought, be readily acceptable to a peasant people. It became deeply rooted, and in certain localities took special forms, reflected many centuries later in rites like those of Ma at Comana, Kybele in Phrygia, Artemis at Ephesus, and, latest of all, Semiramis at the post-Hittite city at Carchemish. From the sculptures of Boghaz-Keui[836] it may be seen that, as in Babylonia, there was already associated with her a youth, whose male powers were necessary to complete her own. With her also there appears a lioness or panther whose force and character seemed to be emblematic of hers. Though clearly attributable to an earlier phase of thought, this association may have been made before the cult was localised. There are, however, traces in these sculptures of more primitive conceptions, attributable to older strains of population. From the evidence in general, four or five strata, indeed, may be discerned in the Hittite pantheon. In the lowest of these there appear the purely elemental forms, mountains and streams,[837] earth,[838] sun,[839] moon[840] and star.[841] Passing from the inanimate to the animate, we find the lion,[842] the bull,[843] the eagle,[844] the falcon or dove,[845] the goat,[846] the stag, the serpent[847] and other living creatures, some of them possibly adopted as tribal totems, and all no doubt representing some special virtue or power that later became embodied in the deities associated with them. Upon these substrata the gods of human form appear to be imposed, and first among these the Mother-goddess. Already, as we have noticed in these sculptures,[848] her supreme powers in life and her unfathomable actions had found expression in the semblance of a lion, before she was adopted by the mountain-worshippers; and another class of monument, possibly of later evolution, seems to reveal her in another aspect, as a goddess to be propitiated at death. The two ideas in her case are not far separated; for just as in the simplest conception of her powers through her the dead earth revived, while in her developed cult, her dead son yet lived in her offspring (through her unnatural union with him), so the instinctive belief of humanity in the incompleteness of death found expression in offerings to her for the dead,[849] and in communion of the dead at her table.[850] The idea of a future life after death was inseparable from her worship.
