Bibliotheca Hagiographica Orientalis

The Bibliotheca Hagiographica Orientalis is a catalogue of Arabic, Coptic, Syriac, Armenian, and Ethiopian hagiographic materials, including ancient literary works on the saints' lives, the translations of their relics, and their miracles, arranged alphabetically by saint. It is usually abbreviated as BHO in scholarly literature. The listings include MSS, incipits, and printed editions. The BHO along with the Bibliotheca Hagiographica Graeca and Bibliotheca Hagiographica Latina are the most useful tools in the research of literary documents concerning the saints.
