Question: Which is the oldest ancient religious text that mentions Tripura? Passage 1:At Dark Horse Comics, Grant wrote several limited and ongoing series in the short-lived Dark Horse shared superhero continuity, including the entire two-year run of the series X. His creation Enemy, published by Dark Horse, was optioned and produced as a Fox pilot, but ultimately did not air. He wrote numerous stories for DC Comics in the 1990s and created new versions of Manhunter and the Challengers of the Unknown. He continued to periodically write for Marvel Comics, his last major contribution being X-Man in collaboration with Warren Ellis and Ariel Olivetti. Among his other creator-owned works of the 1990s were the superhero comic Edge, with Gil Kane, published by Malibu Comics/Bravura, and the crime series Damned with Mike Zeck, published by WildStorm.
 Passage 2:He made only a handful of appearances at the Britannia Stadium in 2003–04, though he earned a £50,000 move to Bristol City in the January transfer window. He played in the play-off final defeat to Brighton & Hove Albion, replacing defender Tony Butler on 88 minutes as manager Danny Wilson made a late attempt to save the game. He did not feature heavily at Ashton Gate and instead was loaned out to Port Vale in October 2004. The next month Swansea City manager Kenny Jackett was on the lookout for a quality winger, Goodfellow meanwhile was prepared to go out on loan to the League Two club. Jackett managed to persuade City to allow Goodfellow to join the "Swans" on loan. He impressed at the Welsh club and his loan spell was extended the following month. However, he was quickly recalled to Ashton Gate after a spate of injuries at the Bristol club. Soon after Swansea attempted to buy Goodfellow off City, however, City manager Brian Tinnion informed Goodfellow he still had a future at the club. Tinnion was expecting at least what they paid Stoke for him and Swansea were unable to comply. In March 2005 he joined Colchester United on loan until the end of the season and scored once against Peterborough United.
 Passage 3:Although there is no evidence of lower or middle Paleolithic settlements in Tripura, Upper Paleolithic tools made of fossil wood have been found in the Haora and Khowai valleys. The Indian epic, the Mahabharata; ancient religious texts, the Puranas; and the Edicts of Ashoka – stone pillar inscriptions of the emperor Ashoka dating from the third century BCE – all mention Tripura. An ancient name of Tripura is Kirat Desh (English: "The land of Kirat"), probably referring to the Kirata Kingdoms or the more generic term Kirata. However, it is unclear whether the extent of modern Tripura is coterminous with Kirat Desh. The region was under the rule of the Twipra Kingdom for centuries, although when this dates from is not documented. The Rajmala, a chronicle of Tripuri kings which was first written in the 15th century, provides a list of 179 kings, from antiquity up to Krishna Kishore Manikya (1830–1850), but the reliability of the Rajmala has been doubted.
