Ribhus

Ribhus (Sanskrit: ऋभु, ṛbhu, also Arbhu, Rbhus, Ribhuksan) is an ancient word whose meaning evolved over time. In early layers of the Vedic literature, it referred to a sun deity. It evolved to being a wind deity, thereafter referred to three artisan elf men whose abilities and austerities make them into divinities in later Vedic texts. Their individual names were Ribhu (or Rhibhu), Vaja and Vibhvan (also called Vibhu), but they were collectively called Rhibhus or Ribhus (ṛbhú-, pl. ṛbhava, also called Ribhuksan). Their name's meaning is "clever, skillful, inventive, prudent", cognate to Latin labor and Gothic arb-aiþs "labour, toil", and perhaps to English elf.
