Dear learned ones- since my queries to this list have in the past been so generously answered, I shall try again. I am interested in any and all liturgical prayers which begin with the words *o martyr desiderio*. As I mentioned in an earlier missive on the origins of the crucisignatus, I am working on the correspondences between the 14th c. Franciscan office of Saint Louis of France and Julian of Speyer's 13th c. office to Francis (of which there are many). According to Andrew Hughes' electronic database of saints' offices this line is unique to these two saints, with the exception of a later office (15th c) to Augustine. But, as expansive as Hughes' database is, it still represents only one fraction of medieval liturgy. I have also checked the modern index to the Analecta Hymnica (which confirmed but did not expand on the results from Hughes' database). So my question is, can anybody tell me anything about the use of "o martyr desiderio", liturgically or otherwise. many many thanks in advance. cecilia gaposchkin %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
