DR. ACHILLI AND THE INQUISITION AT ROME.--Popish policy by the Inquisition, at the present time, may be seen strikingly illustrated in the case of Dr. Achilli. His instructive volume records, according to its title, his “Dealings with the Inquisition.” He was born at Viterbo, in Italy, in 1803, and took the Dominican habit at the age of sixteen. In the year 1821 he was ordained a priest, and in 1826 appointed professor of various sciences in the Seminary and Bishops’ College at Viterbo. He filled the chair of Theology in the college of the Dominicans till 1833, when he was elected Regent of Studies, and Primary Professor in the College of Minerva, at Rome. He was then appointed Visitor, in the Roman States and in Tuscany, of the convents of the Dominicans, among whom he continued till 1839, when, disgusted with his order of monks, he left it by permission of Pope Gregory XVI., and preached four years at Naples. He returned in 1841 to Rome, where he was imprisoned for a hundred days in the Inquisition. From this he was liberated, in July, 1842, on renouncing, for perpetuity, all his honours and privileges; and the Holy Office decreed his dismissal from all branches of the ecclesiastical ministry. In October he left Italy and became a British subject, being employed as a professor of theology in the Malta Protestant College, especially for the training of young men, converts from Rome, for the evangelical ministry in Italy. In 1848, he came to England; but the revolution in Rome, and the flight of the Pope, led him to return to that city, to advance the cause of Christ, by preaching and circulating the Scriptures. He left London, January 8th, 1849, and entered Rome, February 2nd; on the 5th the Constituent Assembly met, forming a republic. On the 24th of June, Dr. Achilli married the daughter of Captain Hely; and on the 3rd of July the French army took possession of Rome, after a siege of three months, restoring the government of the Pope, under a triumvirate of cardinals. The prisons of the Inquisition were immediately crowded with their victims. No less than sixty priests, who had ministered consolation to the wounded and dying patriots, were seized and imprisoned; and, by the authority of the cardinals, aided by six French soldiers, three officials of the Inquisition arrested Dr. Achilli at midnight, July the 29th, and immured him in their dungeons. But the great wall of the Holy Office having been destroyed in the siege, he was removed next day to the Castle of St. Angelo. His imprisonment was soon known, and the religious community in England was roused at the outrage, so that the Council of the Evangelical Alliance presented strong appeals to the British and French governments on his behalf, and sent two gentlemen as a deputation to Rome. They were not allowed to see him; but, on account of this excitement, he was treated with comparative mildness: yet, it seemed, that he was designed to be sacrificed on the return of the Pope.
