According to the _Oxford Dictionary_, they are “the three genii of the seasons in Hindu mythology”. The Sanskrit word “Ribhu” is sometimes compared with the Germanic word “Elf”. Professor Macdonell considers it “likely that the Ribhus were originally terrestrial or aerial elves”.[53] They are evidently of common origin with the Teutonic elfin artisans who are associated with Thor, the Germanic Indra. [53] _A History of Sanskrit Literature_, pp. 106, 107. The mother of the Ribhus was Saranyu, daughter of Twashtri, “the Hindu Vulcan”, the “master workman”. Twashtri forms the organism in maternal wombs and supports the races of man.[54] As we have seen, he was the fashioner of Indra's thunderbolt: similarly the Teutonic elfin artisan Sindre makes Thor's hammer.[55] [54] _Rigveda_, ii, 53; iii, 55. [55] _Teutonic Myth and Legend_, pp. 35-9. The two groups of Teutonic wonder-smiths were rivals; so were the Ribhus and Twashtri. The elfin artisans prove their skill in both cases by producing wonderful gifts for the gods. Loke acts as a mischief-making spy in Germanic myth, and Dadyak in Indian, and both lose their heads for wagers, but save them by cunning. The Ribhus had provided the Celestials with horses and chariots, but Twashtri fashioned a wonderful bowl which filled itself with Soma for the gods. In the contest that ensued the Ribhus transformed the bowl into four cups. “This bowl”, says Professor Macdonell, “perhaps represents the moon, the four cups being its phases.” One of the Ribhus was a famous archer, like the elfin artisan Egil of Teutonic mythology. The artisan of Babylonian mythology is Ea, father of Bel-Merodach. He is “King of the abyss, creator of everything, lord of all”. He was the god of artisans in general, and is identified with the sea-deity of the Persian Gulf—half-fish, half-man—who landed “during the day to teach the inhabitants the building of houses and temples, the gathering of fruits, and also geometry, law and letters”. His pupils included “potters, blacksmiths, sailors, stonecutters, gardeners, farmers, &c.”[56] [56] _The Religion of Babylonia and Assyria_, T. G. Pinches, LL.D.
