Jain stupa

[5] However the Jain stupa has a peculiar cylindrical three-tier structure, which is quite reminiscent of the Samavasarana, by which it was apparently ultimately replaced as an object of worship.

[6] The drum of the stupa is elongated and cylindrical, and formed of three superposed tiers separated by railings and decorated bands.

[6] By 100 BCE, a relief from Mathura is known, the Kankali Tila architrave, representing centaurs worshipping a Jain stupa.

[14][15] Here again the Jain stupa in the middle of the relief is of cylindrical type with a three-tier design, separated by three horizontal railings.

[16] The centaurs appearing in the Mathura reliefs, as in other places such as Bodh Gaya, are generally considered as Western borrowings.
