Rishabhanatha, also Adinatha, the "First Lord," or simply Rishabha, is the first of the twenty-four Tirthankaras, the "ford-makers" who, in each descending world-age, rediscover and teach the path across the ocean of rebirth. In the reckoning of time Jains hold to, he opens the present avasarpini, the current descending half-cycle, and his emblem is the bull.
The tradition places him at the very dawn of civilisation and gives him a distinctive double role. Before he is a renouncer he is a culture-founder: when the kalpavriksha, the wish-fulfilling trees that had sustained an earlier, effortless age, ceased to provide, Rishabha is said to have taught humankind the arts of survival and society, agriculture, fire, crafts, writing, arithmetic, law and kingship, and only then to have renounced his own sovereignty to seek liberation. Jain accounts name his birthplace as Ayodhya, his parents as King Nabhi and Queen Marudevi, and himself as the founder of the Ikshvaku dynasty.
This belongs to Jain sacred history, not to the documented past. Rishabha is set in a remote, prehistoric antiquity, and the immense lifespans and stature the texts assign the ford-makers of that age are read within the tradition's cosmology rather than as historical record.
