The catalogue, as drawn up by him, is still preserved, and, notwithstanding these disadvantages, is described as a highly creditable performance, and “a valuable supplement to the labours of Talmar and the Assemanis;”[345] and at all events it was to his long and laborious researches while engaged in its preparation, that he owed that minute familiarity with the whole literature of the East, ancient and modern, which, as we shall see, was a subject of wonder even to learned orientals themselves. During the year 1807, an opportunity occurred for testing practically how far the reputation which he had acquired corresponded with his real attainments. On the outbreak of hostilities between the Porte and Russia in that year, the Russian ambassador, Italinski, withdrew (not without some risk and difficulty)[346] from Constantinople, and, being conveyed on board the British ship of war, Canopus, to Malta, afterwards made his way to Ancona. While the ambassador remained at Ancona, the chancellor of the embassy, Angelo Timoni, who was of Bolognese origin, came to visit his native city; accompanied by Matteo Pisani, the official interpreter, who was one of the best linguists of his time, and especially a perfect master of all the modern languages of the East. As they resided, during their stay at Bologna, in the house of his friend, Dr. Santagata, their visit was a severe ordeal for Mezzofanti, who was constantly in their society; but he withstood it triumphantly; and Santagata records their wonder and delight to find that, without ever having visited the East, or mixed in Oriental society, the Bolognese professor had nevertheless attained a “mastery over the many and various languages, especially Oriental ones, in which they tried him, and that the marvellous and all but inconceivable accounts which they had received regarding him, proved to be not only credible but actually true.”[347]
