It is described in Purāṇa(Purana; Mythological Scripture) that the inhabitants of Śākadvīpa (Sakadwipa; the island of Saka)were divided into four varṇas (varna; caste according to vocation) like the ancient Aryan society in India. Ṛṣabha (Rishabha) was one of the four varṇas prevalent among the inhabitants of Śākadvīpa. Probably the term Ṛṣabha was used to denote the kṣatriya (kshatriya) varṇa.
