He revisited the East in 1843, in order to sketch the monuments discovered by M. Botta at Khorsabad. In consequence of this employment, the publication of the results of the Persian journey was greatly delayed. The ‘Voyage en Perse’ was not even written till 1850, and it did not appear till the following year.[192] The folio edition with plates bears no date. A portion of the plates was used by Mr. Fergusson in 1850, for his book on the Palaces of Nineveh and Persepolis, but they were not available the year before.[193] They brought home two hundred and fifty-four drawings and thirty-five copies of inscriptions, most of which they profess to have executed on the spot;[194] and the collection forms an extremely valuable addition to our knowledge of the antiquities of Persia. M. Flandin was strongly of opinion that no individual enterprise could hope to compete with the minuteness of research and the untiring industry of an official like himself, who was charged with a Government mission, and invested with the confidence of two academical bodies.[195] A Government can indeed afford to publish a book no one can afford to buy, but it seems unable to imbue its commissioners with the energy so frequently displayed by private individuals. The lamentable failure of Messrs. Flandin and Coste before the rock of Behistun and the tomb of Darius; besides the serenity with which they abandoned even an attempt to reach Susa, afford sufficient evidence of this. M. Coste is scarcely even mentioned in the ‘Voyage’; but we see enough of M. Flandin to recognise that he did not possess the qualities that make a successful explorer. His narrative is interrupted and disfigured by puerile details of personal adventure in which he evinces a complete absence of the coolness, the nerve and the tact requisite for his task. He magnifies to absurd proportions the risks to which he is exposed; he is constantly involved in humiliating personal encounters with the people of the country, in which he displays vastly more temper than courage. The reader might be tempted to regard these conflicts with some complacency, if it were not for the excruciating punishment with which the politeness of the Persian authorities thought fit to visit his assailants.[196] Very little more now remained to be done to illustrate all that is necessary to know of these Persian ruins. The inscriptions had been successfully recovered and many times copied. The Persian text had been fully translated, and only a few obscure passages awaited farther elucidation. Still the most careful accounts were found to conflict on many points, and neither Porter nor his successors had removed the discrepancies and contradictions that had been so long remarked.
