In the Ganapatya tradition founded in the
Ganesha Purana and the
Mudgala Purana, Ganesha is worshipped as one of the five principle deities along with Siva, Vishnu, the Sun, and the Goddess. The date of composition for the
Ganesha Purana and the
Mudgala Purana—and their dating relative to one another—has sparked academic debate. Both works were developed over time and contain age-layered strata. Anita Thapan reviews comment about dating and provide her own judgment. "It seems likely that the core of the Ganesha Purana appeared around the twelfth and thirteenth centuries", she says, "but was later interpolated." Lawrence W. Preston considers the most reasonable date for the
Ganesha Purana to be between 1100 and 1400, which coincides with the apparent age of the sacred sites mentioned by the text. R.C. Hazra suggests that the
Mudgala Purana is older than the
Ganesha Purana, which he dates between 1100 and 1400. However, Phyllis Granoff finds problems with this relative dating and concludes that the
Mudgala Purana was the last of the philosophical texts concerned with Ganesha. She bases her reasoning on the fact that, among other internal evidence, the
Mudgala Purana specifically mentions the
Ganesha Purana as one of the four Puranas (the
Brahma, the
Brahmanda, the
Ganesha, and the
Mudgala Puranas) which deal at length with Ganesha. While the kernel of the text must be old, it was interpolated until the 17th and 18th centuries as the worship of Ganapati became more important in certain regions. Another highly regarded scripture in the
Ganapatya tradition, the Sanskrit
Ganapati Atharvashirsa, was probably composed during the 16th or 17th century. The
Ganesha Sahasranama is part of the Puranic literature, and is a litany of a thousand names and attributes of Ganesha. Each name in the
sahasranama conveys a different meaning and symbolises a different aspect of Ganesha. Versions of the
Ganesha Sahasranama are found in the
Ganesha Purana. ==See also==
