The "editio princeps" appeared at Rome in 1583, under the title: "Martyrologium romanum ad novam kalendarii rationem et ecclesiasticæ historiæ veritatem restitutum, Gregorii XIII pont. max. iussu editum". It bears no approbation. A second edition also appeared at Rome in the same year. This was soon replaced by the edition of 1584, which was approved and imposed on the entire Roman rite of the Church by Pope Gregory XIII. Baronius revised and corrected this work and republished it in 1586, with the "Notationes" and the "Tractatio de Martyrologio Romano". The Antwerp edition of 1589 was corrected in some places by Baronius himself. A new edition of the text and the notes took place under Pope Urban VIII and was published in 1630. Pope Benedict XIV was also interested in the "Roman Martyrology": his Bull of 1748 addressed to John V, King of Portugal, was often included as a preface in printed copies of the "Roman Martyrology".
