Botta and his successor, Victor Place, excavated intermittently at Khorsabad for ten years, uncovering the palace and making a plan of it, excavating the city walls and gates, studying the drainage of the ancient town, and fully describing the whole. Although a part of the antiquities found were lost in the Tigris by the wreck of a raft on which they were being floated down the river, a large collection reached France, where they are preserved in the Louvre. _By Layard._--The success of Botta fired the enthusiasm of Austen Henry Layard, a young Englishman of Huguenot descent, who began to excavate in 1845 at Nimrûd, a mound further down the Tigris than Mosul, and the site of the Biblical Calah (Gen. 10:11). His money was at first furnished by a few friends, but as he soon discovered a royal palace there similar to the one Botta had unearthed at Khorsabad, the trustees of the British Museum commissioned him to excavate for them. He thus continued the work intermittently until 1849. During this time he spent most of his energy upon the mound of Kouyunjik, where he discovered another royal palace. This palace proved to be the work of Sennacherib, the son of Sargon (named in 2 Kings 18:13; Isa. 36), who built the one at Khorsabad, while the palace at Calah was, in its final form, the work of Esarhaddon, the son of Sennacherib. (See 2 Kings 19:37.) The palace at Nineveh had in turn been repaired by Esarhaddon’s son, Assurbanipal. _By Loftus and Rawlinson._--As these excavations progressed, others were stimulated to make minor explorations. Thus in 1850 William Kennett Loftus carried on small excavations at the mound of Warka, the site of the Biblical Erech (Gen. 10:10), in southern Babylonia, from which he recovered important antiquities. From 1851-1855 the oversight of English excavations was entrusted to Sir Henry C. Rawlinson, the British consul-general at Bagdad. Under his direction J. E. Taylor, British vice-consul at Bassorah, made an excavation at the mound of Mugheir, the site of Ur of the Chaldees, where he unearthed important inscriptions. At the same time Loftus was traveling about Babylonia collecting antiquities.
