Shiva Purana.

By concept, TriDevas( Brahma, Vishnu & Shiva) are fundamental and no one created them. However, Padmapurana speaks of Vishnu creating Shiva. However Padmapurana may not be a real purana. It was created by some cultists hoping to spread their influence.The Puranas are basically stories created to make people understand the truth of Vedas. These stories differ from Puranas to Puranas as they are not the absolute truth.Any person hoping to worship his chosen form-Brahma,Vishnu or Mahesh(Shiva ) reads the particular Purana to increase his or her devotion. As such there is no need to compare and classify the Puranas as done by Padmapurana.

Some of the well-known classical Sanskrit holy books are the Vedas (Rigveda, Samaveda, Yajurveda, Atharvaveda), Upanishads, Bhagavad Gita, Ramayana, Mahabharata, and the Puranas (such as Vishnu Purana, Shiva Purana, etc.). These texts are considered sacred in Hinduism and contain religious teachings, spiritual insights, and epic narratives.

The population of Bagha Purana is 21,617.

Krista Purana was created in 1616.
