NOTE. The following sketch shows us a temple of the Assyrians at Assur as restored by the excavators. Behind the temple court is the holy of holies, and on each side of it rises a temple tower with a winding ascent, after the old Babylonian manner (§ 152). It was from. such towers that the tower architecture of the early world arose, eventually producing our own church spires, of which the Babylonian temple tower was the ancestor (see Fig. 272).
