Janamejaya

[2] The Aitareya Brāhmaṇa states that he was a great conqueror and that his purohita (family priest) Tura Kāvaṣeya consecrated him as king and officiated his aśvamedha (horse sacrifice).

The Śatapatha Brāhmaṇa mentions that he along his brothers Ugrasena, Bhīmasena, and Śrutasena performed an aśvamedha, officiated by Indrota Daivāpa Śaunaka, in order to cleanse themselves of sin.

[5] Michael Witzel states the Pārikṣita dynasty corresponds with the presence of Black and Red Ware in the Punjab and West and South regions of North India, which archeologically dates to 1180 BCE.

He suggests that there "is an intrusion into the genealogical texts" of the late, post-Vedic tradition, which also has two of Janamejaya's father Parikṣit, possibly "invented by genealogists to account for anachronisms" in the later parts of the Mahābhārata, as "a bardic duplication of the same original individual regarding whose exact place in the Kuru genealogy no unanimous tradition had survived.

"[7][note 1] Four copper-plate grant inscriptions purportedly issued during Janamejaya's reign were discovered in the 20th century, but were proved to be fake by historians.

[14] The initial chapters of the epic narrate various aspects of his life including his conquest of Takshasila and about his encounter with Nāga Takshaka.

The mass sacrifice was started on the banks of the river Arind at Bardan, now known as Parham, a corrupt form of Parikshitgarh.

[citation needed] A masonry tank (reservoir) said to have been built by King Janamejaya to mark the site of the sacrificial pit, known as Parikshit kund, still exists in Mainpuri district.

Close to this village a very large and high Khera-(Regional Word meaning Hamlet) containing the ruins of a fort and some stone sculptures has been found.
