Stupas and temples were usually built by the kings and queens as it was an expensive affair. The kings and queens probably spent money from their treasury to pay the craftsmen who worked to build these splendid structures. Besides, when devotees came to visit the temple or the stupa, they often brought gifts, which were used to decorate the buildings. For example, an association of ivory workers paid for one of the beautiful gateways at Sanchi. Among the others who paid for decorations were merchants, farmers, garland makers, perfume sellers, smiths, and hundreds of men and women who were known only by their names which were inscribed on pillars, railings and walls.
