The Bharhut sculptures represent some of the earliest examples of Indian and Buddhist art, later than the monumental art of Ashoka (circa 260 BCE), and slightly later than the early Shunga-period reliefs on railings at Sanchi Stupa No.2 (starting circa 115 BCE). Though more provincial in quality than the sculpture at Sanchi, Amaravati Stupa and some other sites, a large amount of sculpture has survived, generally in good condition. Recent authors date the reliefs of the railings of Bharhut circa 125–100 BCE, and clearly after Sanchi Stupa No.2, compared to which Bharhut has a much more developed iconography. The torana gateway was made slightly later than the railings, and is dated to 100–75 BCE. Historian Ajit Kumar gives a later date to Bharhut, the 1st century CE, based on stylistic comparisons with datable works of art from the Art of Mathura, particularly sculptures inscribed in the name of ruler Sodasa. Many of the Bharhut remains are now located in the Indian Museum in Kolkata.
