[2][full citation needed] The 12th-century writer Hemachandra wrote that the names Koṭivarṣa, Bāṇapura, Devīkoṭa, Umāvana, and Śoṇitapura all referred to the same place.

Bāṇapura is the apparent ancestor of the present name Bangarh; the place is supposed to be connected with the mythical king Bāṇa.

The earliest mentions about the Kotivarsha town are found in the Vayu Purana (XXIII,209) and the Brihat Samhita (XI, II).

[6] Debīkoṭ was listed in the Ain-i-Akbari as a mahal in sarkar Lakhnauti (the name is spelled "Dihikoṭ" or "Dehīkoṭ" in extant copies of the Ain).

It was only in the following phase (the Kushana period, 200 BCE - 300 CE) a brick built wide rampart wall is found with drains, cesspits and residential buildings made of burnt bricks of a very large size, showing distinct signs of prosperity and burgeoning urbanism.

The excavated materials of the Gupta period are not comparable with the richness and diversity of those belonging to Kushana cultural phase.
