The Ribhus (Sanskrit: ऋभु, ṛbhu) are three at first mortal beings who according to Sayana attained godhood by austerities. Their individual names were Ribhu (or Rhibhu), Vaja and Vibhvan, but after the name of their leader they were collectively called Rhibhus or Ribhus (ṛbhú-, pl. ṛbhava). Their name's meaning is "clever, skillful, inventive, prudent", cognate to Latin labor and Gothic arb-aiþs "labour, toil", and perhaps to English elf. In the Rigveda the adjective in its lexical meaning "skillful" is also applied to Indra, Agni and the Adityas.
