Ciaconius, Peter

, brother to the preceding, and a very learned critic of Spain, was born at Toledo in 1525, and died at Rome in 1581. He was employed with others by pope Gregory XIII. in correcting the calendar, and also in revising an edition of the Bible, and of some other works printed at the Vatican. He wrote learned notes upon Arnobius, Tertullian, Cassian, Caesar, Pliny, Terence, &c. He was the author, likewise, of some separate little treatises, one particularly, “De Triclinio Romano;” which, with those of Fuivius Ursinus and Mercurialis upon the same subject, was published at Amsterdam, 1689, in 12mo, with figures to illustrate the descriptions. ²
