At Mathura, there is an old stupa with the inscription of 157 CE. This inscription records that an image of the tīrthankara Aranatha was set up at the stupa built by the gods. Jinaprabha Suri's Tīrthakalpa, a 14th century work based on ancient materials, mentions that Kubera built a stupa of gold to honor Suparśvanātha for Acharyas Dharmaruchi and Dharmaghosha. In the time of the 23rd tīrthankara, Pārśva, the golden stupa was enclosed in bricks and a stone temple was built outside. Somadeva, the author of the Yasastilaka who lived nearly four hundred years before Jinaprabha Suri, refers to it as built by gods.
