The forecasts of Champollion and Nestor L'Hôte have been confirmed by the excavations of Lepsius and Mariette. The conclusions deduced by the former from their examination of the remains in the Nile Valley have been indirectly corroborated by the discoveries which have successively revealed to us ancient Chaldæa, Syria, Phœnicia, Asia Minor, primitive Greece and Etruria. No one contests the priority of Egypt. It is recognized that its origin dates from a period long antecedent to that of any other race which, in its turn, played the leading _rôle_ upon the stage of the ancient world. Justice has been rendered to the richness of its architecture, to the skill of its painters and sculptors, to the inventive fertility of its handicraftsmen and the refinement of their taste. And yet no one had attempted to do for Egypt what such men as Winckelmann and Ottfried Müller did for Greece, Etruria, and Rome. The methods of analysis and critical description which have long been employed with success upon another field, had never been applied to her art as a whole; no one had attempted to trace the steps of Egyptian genius during its long and slow evolution. The difficulties were great, especially when architecture was concerned. The ruins of the Pharaonic buildings had never been studied at first hand with such care as had been lavished upon the classic monuments of Italy and the Eastern Mediterranean. The works to which we have had to turn for information have many plates which make a fine show, which are accompanied with a luxury of detail which is very reassuring, but when we examine them closely we are amazed to find the most unforeseen omissions in their materials both for restorations, and for the reproduction of buildings in their actual condition. When we attempt to make use of two separate works for the restoration of a temple, we are met with an embarrassment of another kind. Differences, and even actual contradictions, between one author and another are frequent, and that without any new excavations having taken place between-times to account for the inconsistency. Both observers had the same facts under their eyes, and it is often difficult to decide which of the two has observed badly. For one who does not wish to admit pure fancy into his work, all this causes doubts and hesitations which add greatly to the difficulty of his task.
