The external appearance of the great rail may be judged of from the annexed woodcut (No. 36), representing a small section of it. The lower part, or plinth, was ornamented by a frieze of animals and boys, generally in ludicrous and comic attitudes. The pillars, as usual, were octagonal, ornamented with full discs in the centre, and half discs top and bottom, between which were figure sculptures of more or less importance. On the three rails were full discs, all most elaborately carved, and all different. Above runs the usual undulating roll moulding, which was universal in all ages,[130] but is here richly interspersed with figures and emblems. The inside of the rail was very much more richly ornamented than the outside shown in the woodcut; all the central range of discs, both on the pillars and on the rails, being carved with figured subjects, generally of very great elaboration and beauty of detail, and the upper rail was one continuous bas-relief upwards of 600 ft. in length. At the returns of the gateways another system was [Illustration: 37. Angle pillar at Amravati.] [Illustration: 38. Slab from Inner Rail, Amravati.] adopted, as shown in the above woodcut (No. 37). The pillars being narrower, and the discs smaller, the principal sculpture was on the intermediate space: in this instance a king on his throne receives a messenger, while his army in front defends the walls; lower down the infantry, cavalry, and elephants sally forth in battle array, while one of the enemy sues for peace, which is probably the information being communicated to the king. The inner rail, though lower, was even more richly ornamented than the great rail, generally with figures of dagobas--apparently twelve in each quadrant--most elaborately carved with scenes from the life of Buddha or from legends. One of these dagobas has already been given (Woodcut No. 17). Between these were pillars and slabs ornamented, either as shown in Woodcuts Nos. 38 and 39, or with either Buddhist designs or emblems, but all as rich, at least, as these; the whole making up a series of pictures of Buddhism, as it was understood in the 4th and 5th centuries, unsurpassed by anything now known to exist in India. The slab represented in Woodcut No. 38 (p. 101), though now much ruined, is interesting as showing the three great objects of Buddhist worship at once. At the top is the dagoba with its rail, but with the five-headed Naga in the place usually occupied by Buddha. In the central compartment is the chakra or wheel, now generally acknowledged to be the emblem of Dharma, the second member of the Buddhist Trinity; below that the tree, possibly representing Sanga or the congregation; and in front of all a throne, on which is placed what I believe to be a relic, wrapt up in a silken cloth.
