_By Oppert and Rassam._--In 1852 a French expedition under the direction of Jules Oppert reached Babylonia. Oppert made important excavations at Hillah, the site of the city of Babylon, and at Birs Nimrûd, the ancient Borsippa. In 1852 Hormuzd Rassam, who had been one of Layard’s helpers, continued under Rawlinson’s direction the excavation at Nineveh. This work continued until 1854; Rassam had the good fortune to find, in a part of the mound previously untouched, still another palace. This was the palace of Assurbanipal, the last of Assyria’s great kings, who ruled from 668 to 626 B. C., and who collected here a great library. This library Rassam discovered, and as it contained every variety of Babylonian and Assyrian literature, including dictionaries and grammatical exercises, it was one of the most important archæological discoveries ever made. During the last part of the time Rassam was succeeded by Loftus. Finally, in the autumn of 1854, Rawlinson himself undertook an excavation at Birs Nimrûd, and unearthed some important inscriptions of Nebuchadrezzar II, King of Babylon, 604-562 B. C. (See 2 Kings 24, 25.) After this the interest in excavation waned for a time, while scholars were busy reading the tablets already found. _By George Smith._--In December, 1872, George Smith, an employee of the British Museum, announced that among the tablets from Nineveh he had found an account of the flood which closely resembled that in the Bible. This aroused so much interest that the proprietors of the London _Daily Telegraph_ contributed money to send George Smith to Assyria to explore further the mounds there. George Smith thus led two expeditions of exploration, one in 1873 and the other in 1874. He extended the trenches of his predecessors at Nineveh and discovered many more important inscriptions. In 1876 he was on his way to Mesopotamia for the third time, when he died of fever at Aleppo. The British Museum immediately secured the services of Rassam again, who during that year and 1877 extended the work at Kouyunjik (Nineveh) and also found a palace of Shalmaneser III, King of Assyria, 860-824 B. C., at a mound called Balawat, situated to the east of Kouyunjik.
