Pietro Della Valle, an Italian traveller, surnamed II Pellegrino, born in Rome, April 2, 1586, died there, April 20, 1652. In June, 1614, he embarked from Venice in the habit of a pilgrim. He went first to Constantinople, remained a year, then visited Egypt and the Holy Land, and at Bagdad married a Nestorian woman. He next journeyed over Mesopotamia, and finally went to Ispahan and engaged in the war between Persia and Turkey. His wife having died, he embalmed her body and took it home with him, travelling through India, and reaching Rome in 1626. To Pope Urban VIII., who made him honorary chamberlain, he presented a short account of Georgia, in order to induce him to send missionaries to that country. Not long afterward he married a Georgian, whom he had brought with him from the East. His travels, written in the form of letters, were published at Rome in 1650-53 in 4 vols. (English translation, fol., London, 1665). Several other works were composed by him, many of which were never published. His narratives, in spite of their prolixity, are very accurate.
