-secondary creation after periodic annihilation
- genealogy of gods and patriarchs

Creation and dissolution (sarga, "emission" and samhara, "gathering in") occur when Prajapati, a creative figure of the Vedic era, issues the universe and opens it, but everything is always in it, just revealed alternately (manifest) or hidden (latently), sarga leaves it out and samhara pulls it back.
These additional topics include customs, ceremonies, sacrifices, festivals, caste taxes, donations, temple construction and images and places of pilgrimage. The genealogies of the gods, Manus, and kings form an open structure in which individual authors place anything they want to speak (although some Purana ignore genealogies entirely).

The oldest Puranas, probably composed between 350 and 750 are Brahmanda, Devi, Kurma, Markandeya, Matsya, Vamana, Varaha, Vayu and Vishnu. The next of the oldest, composed between 750 and 1000, are Agni, Bhagavata, Bhavishya, Brahma, Brahmavaivata, Devibhagavata, Garuda, Linga, Padma, Shiva and Skanda. Finally, the most recent, composed between 1000 and 1500, are Kalika, Kalki, Mahabhagavata, Naradiya and Saura.
All Puranas are strongly sectarian - some worshipped by Shiva, others to Vishnu or other deities.
