The Adi Parva includes the snake sacrifice (sarpasattra) of Janamejaya, explaining its motivation, detailing why all snakes in existence were intended to be destroyed, and why despite this, there are still snakes in existence. This sarpasattra material was often considered an independent tale added to a version of the Mahābhārata by "thematic attraction" (Minkowski 1991), and considered to have a particularly close connection to Vedic (Brahmana) literature. The Panchavimsha Brahmana (at 25.15.3) enumerates the officiant priests of a sarpasattra among whom the names Dhritarashtra and Janamejaya, two main figures of the Mahābhārata's sarpasattra, as well as Takshaka, a snake in the Mahābhārata, occur.[33]
The Suparnakhyana, a late Vedic period poem considered to be among the "earliest traces of epic poetry in India," is an older, shorter precursor to the expanded legend of Garuda that is included in the Astika Parva, within the Adi Parva of the Mahābhārata.[34][35]
The Greek writer Dio Chrysostom (c. 40 – c. 120 CE) reported that Homer's poetry was being sung even in India.[38] Many scholars have taken this as evidence for the existence of a Māhabhārata at this date, whose episodes Dio or his sources identify with the story of the Iliad.[39]
Several stories within the Mahābhārata took on separate identities of their own in Classical Sanskrit literature. For instance, the Abhijnanashakuntala by the Sanskrit poet Kalidasa (c. 400 CE), believed to have lived in the era of the Gupta dynasty, is based on a story that is the precursor to the Mahābhārata. The Urubhanga, a Sanskrit play written by Bhasa who is believed to have lived before Kalidasa, is based on the slaying of Duryodhana by the splitting of his thighs by Bhima.[40]
The copper-plate inscription of the Maharaja Sharvanatha (533–534 CE) from Khoh (Satna District, Madhya Pradesh) describes the Mahābhārata as a "collection of 100,000 verses" (śata-sahasri saṃhitā).[40]
