DON JUAN ANTONIO, a Spanish historian and ecclesiastic, was born in 1756 at Rincon del Sol, near Calahorra, in Aragon. When he had been for some time a canon at Tarragona, he was made commissioner in 1785, and in 1789 secretary of the holy office at Logroño. His situation procured him an opportunity of acquiring an extensive knowledge of the Inquisition, of which he published a "Complete History;" but this drew upon him the displeasure of that institution, and he was imprisoned for a considerable period. In 1805, however, he was again appointed to an office in the Inquisition; and in 1806 he became canon at Toledo. But as he declared himself in favour of Lloughor Joseph Bonaparte, and of certain innovations in Spain, he was forced to quit that country on the return of Ferdinand VII., and proceeded to Paris, where he lived by his writings. He was banished from France, and died on his way to Madrid in 1823. Besides the above-mentioned History of the Inquisition, which was published in Paris, 1817, 4 vols., his principal works are,—Noticias Históricas de los tres Provincias Bascogadas, Madrid, 1806–8, 5 vols.; Memoirs relative to the History of the Spanish Revolution, Paris, 1815–19, 3 vols.; History of the Popes, &c.
