Composed in about the year 725, the Liber Questionum in Euangeliis (LQE) is a comprehensive reference commentary on Matthew intended for ecclesiastics in the writing, teaching, and preaching professions. Its anonymous Irish redactor gathered together all the relevant patristic and native material available, adding to and adapting much of a still largely unpublished commentary on Matthew by the Hiberno-Latin writer Frigulus (fl. ca. 700). LQE's well-attested manuscript tradition and its far-flung exegetical influence make it one of the more intriguing texts to appear in the Scriptores Celtigenae series. Although LQE's origins are in Ireland (and one Irish fragment still survives), its manuscript families also include witnesses from England and the Continent. Not only is LQE a typical product of the early Irish church, but its considerable length, the variety of its sources, and its influence on later writers further reveal the work to be central to the entire early medieval Gospel commentary tradition. In addition to exegetes in England, the Carolingian writers Haimo of Auxerre (ob. 853), Rhabanus Maurus of Fulda (780-865), and especially Paschasius Radbertus of Corbie (ob. ca. 865) adapted it for their own works on Matthew.

Vatican, Biblioteca Apostolica, Reg. lat. 49, a late 10th-century Breton-Latin manuscript, is a miscellany of Latin religious texts that may have served as a preacher’s source book. Half of its 56 texts were copied or adapted from Hiberno- Latin works. The Vatican manuscript’s homily on the Octave of Easter contains an apparent Old Irish gloss, originally interlinear. Once its language was misidentified and its meaning misunderstood at some point in the manuscript tradition, the gloss was changed into a two-word Latin noun phrase and made part of the Latin text. The phrase, however, makes no sense in its Latin sentence, nor does the noun exist in any Latin dictionary. The Vatican scribe added construe marks to clarify the main elements of the relative clause in which the phrase is found. This paper provides a photograph and transcription of the passage in the manuscript, discusses the purpose of the construe marks, identifies the Old Irish word, and explains why it was an appropriate choice for the Latin word it was intended to interpret.
