There are also chthonic deities, those of the Underworld, but the celestial ones set the tone. As the mighty champion, he is a god of war, particularly against outside dangers and in defense of his people. Another possible name for the moon would be Louksnos, The Shining One (Matasovič, 2009, 122). Bloomington, IN: Indiana University Press, 1992 (1979). Myth, Cosmos, and Society: Indo-European Creation and Destruction. Sarasvatī is trifunctional; a goddess of purity (her white garments again are symbolic of purity) who inspires speech, a consort of heroes, and a giver of gifts, fertility, and healing. For now it is enough that she is described as laying down with her son like a cow with her calf (RV 1.32.9). In Historia Religionum: Handbook for the History of Religions. It doesn't really belong; despite taking part in the Xrtus, and even being an important part of its operation, it doesn't really belong to the Xrtus, because it doesn't have a definite identity. This makes her Proto-Indo-European enough for our purposes, though. A Land Full of Gods: Nature Deities in Greek Religion.
This is necessary if they are to take part in the Xártus, which is a relationship between separate elements. And of course there is the most famous Indo-European dragon-slayer of all, the Vedic Indra (possibly one swollen with power (Mallory and Adams, 1997, 561)). The second half of Demeters name is definitely mother, but although her cult is essentially that of an Earth Mother, the first meaning of the first half does not seem to be Earth.
Because they are constrained by the Xártus, the deities are similar to natural forces. Herakles killed the multi-headed Hydra (Apollodorus, 2.5), the serpent of the Hesperides, and the serpents sent to kill him in the cradle. Aśvins means "horse-men." They are conceived when their mother Saranyū is in the form of a mare (Ward, 1968, 12). Pigs were frequent offerings for Tellus and Ceres (Whatmough, 1931, 178).
Each is part of the working of the universe, and each fulfills their part to perfection. Neither of these two constraints their nature and the Xártus are external to the gods. There is thus nothing above the gods (except for other gods). Notice also that one of these constraints the Xártus is within and behind everything. In the dindshenchas of Mag Muirthemne, the Dagda kills some kind of underwater monster with his thunder-club (lorg anfaidh; Gwynn, 1924, 5, translates it mace of wrath, but thunder-club is equally legitimate, and I think more likely). Pindar (Olympia 3.39) describes the Dioskouroi as "having good horses;" elsewhere (Pythian 5.10), Castor is "gold-charioted," and in Pythian 1.66 they are leukpōloi, "having white horses." The two of them are "the mightiest of hero charioteers" (Pindar, Isthmian 1, p. Alkman (Fragment 12, in Ward, 1868, 12) calls them "skilled riders." The only other Greek god besides them who is described as riding horseback (rather than in a chariot) is Poseidon, who created horses, and him only rarely (Walker, 2015, 25). One of Freyjas names was Syr, sow(Marjanić,2003, 195).
Others are clear in their functions, but lack names. Baltimore: American Philological Association, 1959. The tale of their battle is also represented in stone reliefs (Stone, 1999, 17; Turville-Petre, 1964, 76). Echoes of the twins may also have survived among the Celts, the Anglo-Saxons, and the continental Germans (see OBrien, 1982; Ward, 1968). Myth and Religion of the North: The Religion of Ancient Scandinavia. Yems (or his soul) went to the land of death and became its ruler. These twins didn't just establish the Cosmos and then go away. --Myth, Cosmos, and Society: Indo-European Creation and Destruction. There is a Slavic oath I swear by the Sky and by the Earth! Among the Slavs she was called to witness in land disputes (Gimbutas, 1971, 169; West, 2007, 175).
Most Indo-European deity names are transparent in meaning, originating as descriptions, as titles. One of the panels of the Gundestrup cauldron, a silver-gilt work of art created in the Balkans or northeastern Italy but transported to and discovered in Gundestrup, Denmark, shows a deity holding a wheel, the symbol of the Gaulish Taranis. In Wales we have Pryderi, son of the horse goddess Rhiannon, who is born on May day (a holy day), at the same time as a horse. In Ireland, the hero C Chulainn is also born at the same time as a horse, which also is raised with him. After their deaths they were both deified, although Yems is definitely "more divine" than Mannus, a first among equals. Probably this is as if "on my mother's womb" or perhaps because, like the Sun, she was always present. In A Restructured Translation of Mythologies (2 vol.).
