BULLARIUM. — This term designates any collection of papal bulls or constitutions.
The first attempt to gather or print such documents separately dates to 1550, when a collection of 60 bulls was published in Rome under the title: *Bullae diversorum Pontificium a Ioanne XXII ad Iulium III ex bibliotheca Ludiovici Gomes*. In 1579, also in Rome, a collection of 163 bulls was printed under the title: *Bullae diversorum Romanorum Pontificium a Bonifacio VIII ad Paulum IV*. Still in Rome, in 1579, Cesare Mazzutelli’s collection of 723 bulls was printed; this was followed by the collection of Lorenzo Cherubini (1586–1617) and that of A. M. Cherubini, the latter’s brother (1638). To A. M. Cherubini’s edition, in 4 volumes, Angelo da Lantusa and Giovannino Paolo da Roma added 2 more volumes in 1672. These were the precursors of the *Magnum Bullarium Romanum*: a collection in 32 volumes composed of the 8 volumes edited by Gerolamo Maiorando as a supplement to A. M. Cherubini’s *Bullarium*, the 20 volumes edited by C. Cocquelines, and the 4 volumes of the *Bullarium* of Benedict XIV. The great *Bullarium Romanum* includes papal letters from Leo I to the end of the pontificate of Benedict XIV. Two continuations of it exist: one in 19 volumes published in Rome from 1835 to 1857, and another in 10 volumes published in Prato from 1843 to 1867. The so-called *Bullarium Taurinense*, edited under the direction of Cardinal F. Gaude and A. Tomasetti, comprises papal bulls up to Benedict XIV and consists of 25 volumes: 20 printed in Turin from 1857 to 1872, and 5 printed in Naples from 1867 to 1885. These *Bullaria* do not constitute authentic collections, and none of them is complete.
There are also specialized *Bullaria*, containing documents of a single pope or documents concerning a religious order.
