Origin of Vishnu Purana
In the Vishnu Purana the reference of the Maurya Empire is found. Hence the scholars have surmised it to be composed in the first or second century AD.
Composition of Vishnu Purana
It is divided into six Adisas or Khandas or chapters. It deals with the events of Varahakalpa and contains 23,000 Shlokas. Its character is more that of a unified composition than of a mere compilation, which the case with most of the other Puranas is. It has been narrated by the narrator himself that Vyasa, adept in the composition of Puranas, composed this Puranasarirhita with akhyanas, upikhyanas, githas and kalpanirnayas. A Suta named Romaharsana was Vyasa's chief disciple. Vyasa in order to propagate his teachings among his disciples gave that Samhita to that Suta. Romaharsana had six disciples named Sumati, Agnivarcas, Mitrayus, Sarhsapiyana, Akrtavrana and Savarni. Of these, Akrtavrana, Savarni and Sarhsapiyana born in the Kasyapagotra have composed Puranasamhitas, which are based on the teachings of Vyasa described in Samhita. There is yet another Samhita composed by Romaharsana which became the basis of the sarirhitas of his three disciples. The narrator says that he composed the Vishnu Purana based on the above four Samhitas.
