Q. Which two Jain Tirthankars are mentioned in the Rigveda?
Answer: Rishabhdev and Arishtnemi
Notes: Rishabhdev is the 1st Tirthankara and Arishtnemi (Neminath) is the 22nd Tirthankara in Jainism. Both are explicitly mentioned in the Rigveda. Ajitnath, the 2nd Tirthankara, is mentioned in the Yajurveda but not in the Rigveda. The Rigveda is one of the oldest sacred texts of India, composed around 1500–1200 BCE.
