After Lepsius had returned to Thebes from this excursion, he wrote to Bunsen: “Fortunately the journey to Sinai now lies behind us, and in truth I am heartily glad of it, not only because it was the hardest and most dangerous part of our whole pilgrimage, but also because it presented the most important and difficult problems which still remained to be solved on our return journey. Now nothing remains but the departure from Thebes and from Cairo; and, this, too, is only a question of getting ready to leave, there is nothing more of importance to be undertaken. When I consider all the material which we have collected in the three years it almost terrifies me, for I shall never be in a position to work it up, even if we succeed in bringing it home.” Nevertheless, he was afterwards able, as we shall see, to make the whole of it accessible to science. From the Peninsula of Sinai Lepsius went back to Thebes, where he found that his instructions had been excellently carried out. Thence he returned to Cairo, making only short stops in the places where the most important monuments were to be found. On the way he met Dr. Bethmann[60] an old university friend, who had come over from Italy, in order to make the return journey through Palestine with him. Before his departure to the Promised Land, Lepsius superintended the despatching of the treasures which he had collected, and the taking apart of the tombs from the pyramids to be transported to Berlin. Lastly he visited the localities containing the most important monuments in the Delta. In a letter of the eleventh of July, 1845, he stated the plan according to which he hoped to see the Egyptian antiquities arranged in the new museum at Berlin. This was to be on an historical basis, and was afterwards executed in the manner proposed. He had heard at Cairo, much to his delight, that they had not yet begun to build the halls intended for the Egyptian department of the new museum at Berlin, and that his desire to see every part constructed in the Egyptian style of architecture might yet be carried out from the very foundation. “I think,” he wrote, “that to produce a generally harmonious impression, we must preserve the characteristic styles of building of the different periods, and especially the order of the pillars, in their historical sequence, and also with all their rich colored decoration.” Lepsius still kept his attention fixed upon Egyptian antiquity even during his rapid journey through Palestine, and he was afterwards able to publish,[61] and also to incorporate in his great work on monuments, the best copy of the celebrated tablet chiselled on the living rock, which commemorates the victory of Rameses II. on the Dog river (Nahr-el-Kelb). This is the Lycos of the ancients, and lies north of Berytos (Beirut).
