Basically, its a picture book satire by David Mackaulay of future archeologists opening a site where a motel was, and the ridiculous assumptions they make of each item, such as the "Sacred Altar" which people would lie before for hours...
Thanks for the recommendation. They don’t have it on the Kindle yet though.
I read that when it first came out in the late 70's; supposedly it was influenced by the tour of the King Tut exhibit. Another book in that same vein (which preceded Motel, and which delves somewhat deeper into the division of religion and science is Walter Miller's A Canticle for Leibowitz, also very well worth taking the time to read.
