There are 1 Maha Purana, 17 Mukhya Puranas (Major Puranas) and 18 Upa Puranas (Minor Puranas),[7] with over 400,000 verses.[2] The first version of various Puranas were likely to be composed between 3rd- and 10th-century CE.[8]
Markandeya purana
The Markandeya text is probably one of the oldest Puranas in Hinduism.[2][15] The text’s literary style and content, wherein the early chapters read like a supplement to the Hindu epic Mahabharata has led scholars to suggest it is an early composition that likely followed the epic.[2]

The text has also been dated with the help of epigraphical evidence.[2][17] The Dadhimati Mata inscription, for example has been dated to be from 608 CE, and this inscription is a quote from chapter 10 of the Devi Mahatmya (91st chapter of the Purana). This suggests that this part of the text existed by the 6th century CE.[2][17] A complete Palm-leaf manuscript of the text was discovered in Nepal, and has been dated to 998 CE.[14] Similarly, the early 8th-century text Malatimadhava of Bhavabhuti references Devi Mahatmya, which implies the text was established and in circulation by then. Other scholars have placed it between 4th- to 6th-century CE.[18] The idea of Goddess as the supreme, states John Lochtefeld, likely existed before the 6th-century than the composition date of Devi Mahatmya, because it appears in so fully developed form in the text.[18][3]
