The Phrygians ... select a natural hillock, run a trench through the middle of it, dig passages, and extend the interior space as widely as the site admits. Over it they build a pyramidal roof of logs fastened together, and this they cover with reeds and brushwood, heaping up very high mounds of earth above their dwellings. Thus their fashion in houses makes their winters very warm and their summers very cool.
vitruvius...a vision of daring and dainty loveliness, of story of rosy masonry and delicate overhanging balconies and latticed windows, soaring with tier after tier of fanciful architecture in a pyramidal form, a very mountain of airy and audacious beauty , through the thousdnad pierced screens and gilded arches of which the Indian air blows cool over the flt roofs of the very highest house. Alladin’s magician could have called into existence no more marvelous abode.
