The process by which the simple Ćaitya or mound developed into more elaborate structures is remarkable. First came erections of stone or brick, generally bell-shaped or domed like bee-hives. These again expanded into elongated pyramidal structures, springing from cylindrical or octagonal or hexagonal bases, and ornamented with images of Gautama, and resting on plinth-like foundations, the summits tapering into finials consisting of three, or seven, or nine, or eleven, or even fifteen tiers of umbrella-shaped ornaments (see [note, p. 393]).
Then, again, in time, these elaborate Dāgabas expanded into vast Pagodas of enormous height, as, for example, the Rangoon Pagoda (see [p. 456]) and that at Anurādha-pura in Ceylon.
It is doubtful whether in early Buddhism Ćaityas and Stūpas were ever empty monuments or cenotaphs. Probably all of them contained ashes, fragments of bone, teeth, or hair, though in some cases the most careful examination has failed to discover the vessel in which they were deposited. If made of fragile materials, it rapidly crumbled into dust. But Stūpas, even without relics, were themselves objects of reverence.
In the later period of Buddhism the practice of carving, or moulding mere memorial or votive Stūpas, and dedicating them at sacred spots became common. The examples of this kind of Stūpa which I saw unearthed at Buddha-Gayā have been described ([p. 397]).
The engraving opposite to this page is a copy of one of these votive Stūpas which I procured for the Indian Institute through Mr. Beglar.
At Mandalay there is a large Pagoda with about 620 smaller ones round it (in rows of six or seven deep). Each small Pagoda enshrines a tablet—exposed to view—on which some portion of the Law is engraved. Many small Pagodas are simply canopies of brick or some solid material erected over images.
Outside the Buddhist convent near Dārjīling, when I visited it in 1884, a monk was roughly moulding a number of small votive Stūpas in clay, with which he was probably mixing the powdered bones of some deceased Lāma. Here is a copy of one exactly the size of the original:—
If broken open, a terra-cotta seal, inscribed with some sacred formula, would probably be found inside.
Of course most of the Buddha’s chief disciples, such as Sāriputta, Maudgalyāyana, Kāṡyapa, Ānanda, Upāli, each had Stūpas erected over their relics.
