The names and success of these missionaries are recorded in the _Mahawanso_, or Sacred History, translated by Mr.George Turnour from the Singhalese.

But what is remarkable is, that the relics of some of them have been recently found in the Sanchi topes, and in other sacred buildings, contained in caskets, with their names inscribed on them.

These inscribed names correspond with those given to the same missionaries in the historical books of Ceylon.
For example, according to the _Mahawanso_, two missionaries, one named Kassapo (or Kasyapa), and the other called Majjhima (or Madhyama), went to preach in the region of the Himalayan Mountains.

They journeyed, preached, suffered, and toiled, side by side, so the ancient history informs us,--a history composed in Ceylon in the fifth century of our era, with the aid of works still more ancient;[104] and now, when the second Sanchi tope was opened in 1851, by Major Cunningham, the relics of these very missionaries were discovered.[105] The tope was perfect in 1819, when visited by Captain Fell,--"not a stone fallen." And though afterward injured, in 1822, by some amateur relic-hunters, its contents remained intact.

It is a solid hemisphere, built of rough stones without mortar, thirty-nine feet in diameter; it has a basement six feet high, projecting all around five feet, and so making a terrace.
