_Don Pedro del Frago_, bishop of Jaca, was born in 1490, in Uncastillo, in the diocese of Jaca. Pedro studied at Paris, and became a Doctor of the Sorbonne: he learnt Hebrew and Greek, and was considered one of the best Latin poets of his age. He was appointed theologian to Charles V., for the first convocation of the Council of Trent; he assisted at it in 1545, and when the second assembly took place in 1551, he preached a Latin sermon to the fathers, on Assumption-day: this discourse forms part of the collection of documents relating to the council. In 1561, Philip II. created him Bishop of Alguer in Sardinia, and he attended the third convocation of the council in that quality. Don Pedro was made, first, Bishop of Jaca, in 1572; and in the following year, when he was sixty-four years of age, the Council of the Inquisition commanded the inquisitors of Saragossa to take informations against this worthy prelate, as suspected of heresy, because he had been denounced as not being known to confess himself, and that he had no regular confessor; he was likewise accused of not celebrating mass with sufficient solemnity. It is surprising that the council should admit these charges, since a bishop is not obliged to have a regular confessor, and it is not necessary for any person to confess, so that the public may be informed of it. The other charge brought against an old man of sixty-four, shows that there was nothing more serious to accuse him of. Philip II., to reward his services, gave Don Pedro the bishopric of Huesca, in 1577, where he founded an episcopal seminary. He died in 1584. He held a synod at Huesca, in which he established constitutions, which he had drawn up and caused to be printed; he also composed a Journal of the most remarkable events in the Council of Trent, from the year 1542 to 1560, and much Latin poetry. Among the doctors of theology of the Council of Trent, who were persecuted or punished by the Inquisition, the most celebrated is _Benedict Arias Montano_, perhaps the most learned man of his age in the oriental tongues. Several towns in Spain have disputed the honour of being the place of his birth. Montano understood Hebrew, Chaldee, Syriac, Arabic, Greek, Latin, French, Italian, English, Dutch, and German: he was almoner to the king, a knight of the order of St. Jago, and doctor of theology in the university of Alcala.
