390 A HISTORY OF ART IN CHALD^A AND ASSYRIA. Thomas. They are inclined to believe that it was an observatory rather than a temple, and tinder that title they have described it. Although we have made use of the name thus given we do not think it has been justified. There is nothing, says M. Place, among the ruins at Khorsabad to show that the tower ever bore any chapel or tabernacle upon its apex. But according to their own hypothesis it has lost its three highest stories, so why should they expect to find any vestige of such a chapel, seeing that it must have been the first thing to disappear ?
