Ṛṣabhanātha

thumb|Birth of the Tirthankara Rishabha, folio from the Devasano Pado Kalpasutra, Kalpasutra and Kalakacharya Katha. Gujarat, c. 1500. [[Bharat Kala Bhavan]] Rishabhanatha (Devanagari: ऋषभनाथ), also Rishabhadeva (Devanagari: ऋषभदेव, ), Rishabha (Devanagari: ऋषभ, ) or Ikshvaku (Devanagari: इक्ष्वाकु, Ikṣvāku), is the first (Supreme preacher) of Jainism. He was the first of twenty-four teachers in the present half-cycle of time in Jain cosmology and called a "ford maker" because his teachings helped one cross the sea of interminable rebirths and deaths. The legends depict him as having lived millions of years ago. He was the spiritual successor of Sampratti Bhagwan, the last Tirthankara of the previous time cycle. He is also known as Ādinātha (), as well as Aadishvara (first Jina), Yugadideva (first deva of the yuga), Prathamarajeshwara (first God-king) and Nabheya (son of Nabhi). He is also known as Ikshvaku, establisher of the Ikshvaku dynasty. Along with Mahavira, Parshvanatha, Neminatha, and Shantinatha, Rishabhanatha is one of the five Tirthankaras that attract the most devotional worship among the Jains.

According to traditional accounts, he was born to king Nabhi and queen Marudevi in the north Indian city of Ayodhya, also called Vinita. He had two wives, Sumangalā and Sunandā. Sumangalā is described as the mother of his ninety-nine sons (including Bharata) and one daughter, Brahmi. Sunandā is depicted as the mother of Bahubali and Sundari. The sudden death of Nilanjana, one of the dancers sent by Indra in his courtroom, reminded him of the world's transitory nature, and he developed a desire for renunciation.
