Introduction
The database Ut per litteras apostolicas (LITPA) represents an electronic version of the celebrated Registres et lettres des Papes du XIIIe siècle (32 vols.: Rome, 1883- ) and the Registres et lettres des Papes du XIVe siècle (48 vols.: Rome, 1899- ). Furthermore, it has been enriched with unpublished material (litterae communes of Gregory XI from 1371 to 1375 and the registers of petitions of Urbain V).
Ut per litteras apostolicas provides striking information on the most varied aspects of medieval society: church institutions, the clergy, the papal states, politics, the legal system, taxation, government and finance, secular society, the religious life, intellectual and artistic life, the economy, wars, law and order, the environment and natural disasters, and daily life.
Aims & Scope
Ut per litteras apostolicas provides online the complete collection of papal letters from the thirteenth and fourteenth centuries. But it is the possibility of searching such a resource with powerful software which makes this database so useful. As a result, a documentary source which has been underexploited, or even unexploited, can now be studied. The international community of medievalists will, for the first time, now be able to draw properly on this rich body of material.
This database of papal registers, Ut per litteras apostolicas, provides both more extensive and more intensive searching than has hitherto been possible from the conventional printed publications.
In particular, the user can undertake a search either on the entire database of all the pontificates or on one particular papacy or even a particular year of a papacy, and can refine the search according to various criteria – date, type of letter, place of issue, and so forth – within designated fields which draw their information from independent documentary sources.
It should be possible, for instance, to identify a bull according to its date of publication (both in the Latin original and its modern equivalent) or its reference number in the printed edition, to undertake a word- or name-search taking into account a large number of possible spelling variants (since the software automatically checks alternative spellings based on common variants found in medieval Latin), or to undertake a search by subject-matter (such as on religious life, or another of the subjects mentioned above).
