All these capitals were apparently originally richly gilt, and most of them, as well as some of the best of the sculptures, show traces of gilding at the present day,[212] and, as others show traces of colour, the effect of the whole must have been gorgeous in the extreme. From the analogy of what we find in the contemporary caves at Ajunta and Bagh, as well as elsewhere, there can be little doubt that fresco-painting was also employed: but no gilding, as far as I know, has been found in India, nor indeed any analogue to the Corinthian capital. All the capitals found in India are either such as grew out of the necessities of their own wooden construction, or were copied from bell-shaped forms we are familiar with at Persepolis, where alone in Central Asia they seem to have been carried out in stone. There is little doubt, however, that before the time of the Achæmenians the same forms were used in wood by the Assyrians;[213] and they may have been so employed down to the time of Alexander, if not later. Certain it is, at all events, that this was the earliest form we know of employed in lithic architecture in India, and the one that retained its footing there certainly till long after the Christian Era, and also among the Gandhara sculptures probably to a very late date. It is not difficult to restore, approximately, the front of the cells in these monasteries, from the numerous representations of them found among the ruins, where they are used as conventional frames for sculptures. It probably was owing to the fact that their fronts may have been adorned with paintings representing scenes from the life of Buddha, or emblems of various sorts, that these miniature representations of them were used to convey the same design in sculpture. The form of the wooden framework which filled the upper part of all the great windows of the chaitya halls, from the earliest known examples, is also used for the same purpose in these Gandhara monasteries. Few things among these sculptures are more common than these semicircular frames, filled with sculpture of the most varied design. They are in fact the counterparts of what would have been carried out in painted glass had they possessed such a material. It is to be feared that it is hardly likely we shall now recover one of these cells or chapels in so perfect a state as to feel sure of its form and ornamentation. It would, however, be an immense gain to our knowledge of the subject if one were found, for it is hardly safe to depend on restorations made from conventional representations.
