With respect to the work by which he will be known to posterity, and which has furnished the principal materials for the present life,—his “Description of Africa,”—its extraordinary merit has been generally acknowledged. Eyriès, Hartmann, and Bruns, whose testimony is of considerable weight, speak of it in high terms; and Ramusio, a competent judge, observes, that up to his time no writer had described Africa with so much truth and exactness. In fact, no person can fail, in the perusal of this deeply interesting and curious work, to perceive the intimate knowledge of his subject possessed by the author, or his capacity to describe what he had seen with perspicuity and ease. The best edition of the Latin version, the one I myself have used, and that which is generally quoted or referred to, is the one printed by the Elzevirs, at Leyden, in 1632. It has been translated into English, French, and German, but with what success I am ignorant. PIETRO DELLA VALLE. Born 1586.—Died 1652. Pietro della Valle, who, according to Southey, is “the most romantic in his adventures of all true travellers,” was descended from an ancient and noble family, and born at Rome on the 11th of April, 1586. When his education, which appears to have been carefully conducted and liberal, was completed, he addicted himself, with that passionate ardour which characterized all the actions of his life, to the study of literature, and particularly poetry; but the effervescence of his animal spirits requiring some other vent, he shortly afterward exchanged the closet for the camp, in the hope that the quarrel between the pope and the Venetians, and the troubles which ensued upon the death of Henry IV. of France, would afford him some opportunity of distinguishing himself. His expectations being disappointed, however, he in 1611 embarked on board the Spanish fleet, then about to make a descent on the coast of Barbary; but nothing beyond a few skirmishes taking place, he again beheld his desire of glory frustrated, and returned to Rome.
