The American architect Roger Vogler has had a long relationship with India. The designer of IIT Kanpur, his great obsession is the Kailasa Temple in Ellora, which he has been visiting and studying for a few decades now. The Kailas at Ellora, a fresh look at probably the finest rock-cut monolithic temple in the world, is an intriguing and illuminating survey of the gigantic complex, its interplay of spaces and its sculptures, all from the perspective of its unknown architect, or sthapati, and of Vogel&rsquos attempt to tease out the architectural rationale behind its construction. This is at the heart of the phrase &lsquoa misunderstood masterpiece&rsquo in the book&rsquos title. Although studied by generations of art historians, Vogel contends that no one has ever truly bothered to look at the architectural, and thereby religious, function that this cave temple might have served.
