The "Narada Purana" texts, like other Puranas, exist in numerous versions, but with less variation than other Puranas. Wilson states that both texts are of likely recent composition, probably 16th or 17th century, because the five manuscripts he reviewed had verses mentioning certain events after Islamic invasion and control of the Indian subcontinent. The other unusual part of the manuscripts he examined, states Wilson, is that the descriptions of ritual worship of Vishnu in the text are "puerile inventions, wholly foreign to the more ancient" ideas in Purana genre of Hindu texts.
