It is hardly to be wondered at that Mount Abu was early fixed upon by the Hindus and Jains as one of their sacred spots. Rising from the desert as abruptly as an island from the ocean, it presents on almost every side inaccessible scarps 5000 ft. or 6000 ft. high, and the summit can only be approached by ravines cut into its sides. When the summit is reached, it opens out into one of the loveliest valleys imaginable, six or seven miles long by two or three miles in width, cut up everywhere by granite rocks of the most fantastic shapes, and the spaces between them covered with trees and luxuriant vegetation. The little Nucki Talao, or Pearl Lake, is one of the loveliest gems of its class in all India, and it is near to it, at Dilwarra, that the Jains selected a site for their Tirth, or sacred place of rendezvous. It cannot, however, be said that it has been a favourite place of worship in modern times. Its distance and inaccessibility are probably the causes of this, and it consequently cannot rival either Palitana or Girnar in the extent of its buildings; but during the age of Jaina supremacy it was adorned with several temples, two of which are unrivalled for certain qualities by any temples in India. They are built wholly of white marble, though no quarries of that material are known to exist within 300 miles of the spot, and to transport and carry it up the hill to the site of these temples must have added immensely to the expense of the undertaking. The more modern of the two was built by the same brothers, Tejpala and Vastupala, who erected the triple temple at Girnar (Woodcut No. 127). This one, we learn from inscriptions, was erected between the years 1197 and 1247, and for minute delicacy of carving and beauty of detail stands almost unrivalled even in the land of patient and lavish labour.[270] The other, built by another merchant prince, Vimala Sah, apparently about the year A.D. 1032,[271] is simpler and bolder, though still as elaborate as good taste would allow in any purely architectural object. Being one of the oldest as well as one of the most complete examples known of a Jaina temple, its peculiarities form a convenient introduction to the style, and among other things serve to illustrate how complete and perfect it had already become when we first meet with it in India. The annexed plan (Woodcut No. 129) will suffice to explain the general arrangements of the temple of Vimala Sah, which, as will be observed, are similar to some we have already met, though of course varying considerably in extent and detail.
