IX. 4. The calendars gave rise to the _Martyrologies_; the object of them was to collect, in one volume, from the calendars of the different churches, the names of the martyrs and confessors throughout the world, with a brief mention of the day of their decease, and the place in which they suffered, or which they had illustrated by their birth, their residence, their rank, or their virtues. The Roman Martyrology is mentioned in the following terms by St. Gregory, (Lib. 8. Epist. Indict. 1.) in a letter to Eulogius, the bishop of Alexandria: "We," says his holiness, "have the names of almost all the martyrs collected into one volume, and referred to the days on which they suffered; and we celebrate the solemn sacrifice of the mass daily in their honor. But our calendar does not contain the particulars of their sufferings; it only mentions their names, and the place and time of their martyrdom." The Roman calendar seems to have been adopted generally through the western church. It certainly was received in England. At the council held at Shovesham in 747, by Cuthbert, the archbishop of Canterbury, it was ordered, "That throughout the year, the feasts of the saints should be celebrated on the days appointed by the Martyrology of the church of Rome, with the proper psalms." It was once generally believed to have been composed by St. Jerom; but this opinion is now universally rejected. It suffered much in the middle ages. Pope Gregory XIII., immediately after he had completed the great work of reforming the calendar, used the most earnest endeavors to procure a correct edition of the Roman Martyrology. He committed the care of it to some of the most distinguished writers of his time on ecclesiastical subjects. Among them, Bellarmin, Baronius, and Gavant deserve particular mention. With this edition Baronius himself was not satisfied. He published another edition in 1586: and afterwards, at the instigation of cardinal Sirlet, published a still more correct edition, with notes, in 1598. He prefixed to his edition a dissertation, in which he appears to have exhausted the subject. A further correction of the Roman Martyrology was made by pope Urban VIII. They were all surpassed by that published by pope Benedict XIV., at Cologne, in 1751. But the most useful edition is that published at Paris, in 1661, by father Lubin, an Augustinian friar. It is accompanied with excellent notes and geographical tables. Politus, an Italian divine, published, in 1751, the first volume of a new edition of the Roman Martyrology. It comprises the month of January, but the plan of annotation is so extended, that it fills five hundred folio pages of the smallest print; from the time of Drackenborch's edition of Livy, so prolix a commentary had not been seen. Among other principal Martyrologies, is that of the _Venerable Bede_. After several faulty editions of it had appeared, it was correctly published by Henschenius
