Perhaps the most popular attraction in India after Taj Mahal, the so-called "erotic temples" of Khajuraho were built in between 950-1050 AD in northern Madhya Pradesh State, central India. Phantasmagorical sensuous carvings depicting erotic scenes spawned a multitude of explanations and wild fantasies as to what they represent. The most popular theories claim that they illustrate the Kamasutra book of love and/or were built by an extreme esoteric tantric sect that ruled at the time, such as the skull-bearing Kapalika sect. However, according to scholars (1), while the religious imagery of Khajuraho is tantra-based, it was within the orthodox Brahmanic fold and was influenced by the Vedic revival and Puranic elements, as inscriptions of temples testify. The carvings express a fertility theme prominent in all Indian art.
