Ecclesiae Occidentalis Monumenta Iuris Antiquissima (EOMIA) is a monumental scholarly achievement by Cuthbert Hamilton Turner, compiled between 1899 and 1939. It presents Latin texts of canons, creeds, and letters from early Church councils and synods, primarily from the fourth century, alongside meticulous comparisons of manuscript traditions. Renowned for its philological rigor, EOMIA remains an indispensable resource for Church historians, canon law scholars, textual critics, and students of Latin. Yet despite its scholarly value, EOMIA is notoriously difficult to use. It was published in fascicles over four decades, each with its own internal divisions (pars, tomus, fasciculus) which were inconsistently labeled and sometimes retroactively reclassified. This lack of editorial cohesion left librarians and scholars struggling to organize and bind the volumes, resulting in chaotic pagination and sequencing. The absence of modern navigation aids such as thematic indexing or summaries only compounded the challenge, making EOMIA a bibliographical labyrinth. This new reprint offers a long-awaited solution: it restores Turner's original intended structure, adds newly commissioned introductions on the contents, organization, scholarly value, and practical use of the work, and includes a dual index of names and selected terms to aid navigation and research.
