The appearance of the third volume of the Bullarium Cyprium brings to a conclusion a project that Charles Perrat, who died in 1976, first envisaged as far back as the 1920s. His pupil, Jean Richard, first published material from the Vatican Archives relating to Cyprus in 1947, and, in the course of an unusually long career – he has now passed his ninetieth birthday – has made a huge contribution to the study of Cyprus in the period of the Lusignan kings. Their joint project, with help in its final stages from Christopher Schabel, has now appeared, continuing Schabel's own two-volume Bullarium covering the years 1196–1314 (rev. ante lxii [2011], 809–10). Unlike the earlier volumes, volume iii provides a calendar rather than the full text of the documents. That in itself comes as no surprise when we discover that the editors have located over 2,000 letters relating to Cyprus (not counting the duplicates sent to different addressees and marked ‘in eodem modo’), almost entirely in the registers of the Avignon popes. It is striking that a kingdom as small as Cyprus, with just four Latin dioceses and a population largely comprising non-Latin-rite Christians, should have attracted so much attention from the papal curia. Many of the letters, typically for this period, show the pope granting petitions for matters such as expectations to canonries or permission to marry within the prohibited degrees; others relate to the politics of the age with invaluable information, for example, on the relations between the Cypriot royal house and the kingdom of Cilician Armenia or between the kings and the Genoese. Predictably there is much here that sheds light on the efforts to organise crusades, not least King Peter i's celebrated expedition that briefly occupied Alexandria in 1365. The importance of these papal letters for our understanding of Cyprus in the fourteenth century is immense, especially as no archives survive in the island itself. Together the three volumes of the Bullarium Cyprium will prove to be an invaluable tool. Quite apart from making available a rich seam of primary material, they correct errors in the published registers and in the works of the late W. H. Rudt de Collenberg who, in a series of articles that appeared in the 1970s and 1980s, did much to reveal the potential of the papal registers for the history of Cyprus.
