According to Matsyapurāṇa (Matsyaputana), the wife of Jantu of the Jyamogha race was known as Aiṣvākī (Aiswhaki). She gave birth to Jantu’s son named Sātatva (Satatwa). According to Brahmānḍa (Btahmanda) and Vayupurāṇa (Vayupurana), Aiṣvākī was the wife of Purudvaha of the Jyamogha race. Satva was the son of Purudvaha and Aiṣvākī.
But according to the Lingapurāṇa (Lingapurana), Aiṣvākī was the wife of Aṁśu (Amsu). Aṁśu impreganated Aiṣvākī and she gave birth to Satva. But in Brahmapurāṇa, Aiṣvākī was known as the wife of Madhu of the Vṛṣṇi (Vrishni)lineage. There the son of Aiṣvāki and Madhu was known as Sattvan.
