James Fergusson, an early architectural historian, was the first to interpret the symbolism at Sanchi in a way that we would now consider incorrect. Fergusson misinterpreted the imagery of trees and serpents as symbols of primitive worship, failing to understand the Buddhist context of the site, primarily due to the lack of knowledge of Buddhist texts at the time. It was only later, with the deciphering of the Brahmi script by James Prinsep in 1837, that the Buddhist significance of Sanchi was correctly understood.
