According to Brihadvishnupurana, there are twelve names of the Mithila region.[4] Apart from the name Mithila, its twelve names are "Tirabhukti, Videha, Nemikanan, Gyanshila, Kripapith, Swarnlalangalpadhati, Janki Janmabhumi, Nirapeksha, Vikalmasa, Ramanand Kuti, Vishwabhamini and Nityanangla". Apart from these names some books also mentioned the name Jnanakshetram or Jñānaśilam instead of Gyanshila.[5][6]
In Ramayana, the court of King Janaka attracted scholars from different parts of the Indian Subcontinent. The court of Janaka was the center of discussion of knowledge between the scholars. The Brihadaranyaka Upanishad gives the account of the Shastrarthas organized by the King Janaka at his court. In these Shastrarthas there was exchange of knowledge among the scholars. The translation of Gyanshila or Jnanakshetram is the home of knowledge. Thus the Gyanshila or Jnanakshetram name of Mithila signifies a descriptive epithet of the region.[6]
