260 STRABO. [CHAP. XII. and then redeemed for himself, by Herod the Great. To judge from the accounts of Palestine which are given by Pliny and Tacitus, as well as by Strabo, the balsam-tree and the Dead Sea seem to have been the objects in that country which chiefly at- tracted the attention of the Roman world in ancient times. The description of Arabia, with which this part of the work concludes, is as complete as the knowledge of that age allowed, and embodies the additional information on the subject which Agatharchides had collected. Strabo also relates the events of the campaign which Aelius Callus prosecuted in that country at the command of Augustus, but in respect of geography that expedition did not add much to what was already known. The last book of the Geography is devoted to Africa, and the larger portion of it is occupied with an account of Egypt and the Rest of Egypt, of which country, as we have seen, Strabo Afnca* had personal knowledge. He commences with a description of Alexandria, which is the most elaborate notice of any city that is found in his work1—an honour which it fully deserved from its importance as a commercial, geographical, and scientific centre. The other famous places in Egypt are briefly depicted, in accordance with the author's rule of confining his work within the limits which he originally assigned to it; but his narrative in these parts is sometimes enlivened by personal experiences, such as his inspection of the bull Apis at Memphis2, his witnessing the feeding of the sacred crocodile at Arsinoe3, and his own trepidation, when being ferried across on a frail raft to the island of Philae4. Con- cerning the course of the Nile to the southward of that place he is able to furnish some fresh information from the expedition of C Petronius in Aethiopia5. The remainder of Africa is some- what briefly treated, and Strabo was not aware of the marked projection formed by the northern coast near Carthage opposite Sicily. About Mauretania he might have had more to say, if he had used the treatise of his contemporary Juba, but with that work he does not seem to have been acquainted. 1 17. i. 6—io, 13. 217. i, 31. s 17. i. 38. 4 J7-1. 50- 5 I?- i- 54-
