different from the earlier examples from several centuries before. But the form of the windows on the exterior has changed greatly, almost entirely dropping the imitation of wooden architecture, and showing a decorative treatment of the wide surround to the chaitya arch that was to be a major style in later temple decoration. The last stage of the freestanding chaitya hall temple may be exemplified by the Durga temple, Aihole, of the 7th or 8th century. This is apsidal, with rounded ends at the sanctuary end to a total of three layers: the enclosure to the sanctuary, a wall beyond this, and a pteroma or ambulatory as an open loggia with pillars running all round the building. This was the main space for parikrama or circumambulation. Above the round-ended sanctuary, now a room with a doorway, rises a shikara tower, relatively small by later standards, and the mandapa has a flat roof. How long construction of chaitya halls in plant materials continued in villages is not known. Parallels Toda huts The broad resemblance between chaityas and the traditional huts still made by the Toda people of the Nilgiri Hills has often been remarked on. These are crude huts built with wicker bent to produce arch-shaped roofs, but the models for the chaitya were presumably larger and much more sophisticated structures. Lycian tombs The similarity of the 4th century BCE Lycian barrel-vaulted tombs of Asia Minor, such as the tomb of Payava, with the Indian architectural design of the Chaitya (starting at least a century later from circa 250 BCE, with the Lomas Rishi caves in the Barabar caves group), suggests that the designs of the Lycian rock-cut tombs traveled to India, or that both traditions derived from a common ancestral source. Early on, James Fergusson, in his " Illustrated Handbook of Architecture", while describing the very progressive evolution from wooden architecture to stone architecture in various ancient civilizations, has commented that "In India, the form and construction of the older Buddhist temples resemble so singularly these examples in Lycia". Ananda Coomaraswamy and others also noted that "Lycian excavated and monolithic tombs at Pinara and Xanthos on the south coast of Asia Minor present some analogy with the early Indian rock-cut caitya-halls", one of many common elements between Early Indian and Western Asiatic art. The Lycian tombs, dated to the 4th century BCE, are either free-standing or rock-cut barrel-vaulted sarcophagi, placed
