Old Irish - Sources

Sources

Relatively little survives in the way of strictly contemporary sources. These are mainly represented by shorter or longer glosses on the margins or between the lines of religious Latin manuscripts, most of them preserved in monasteries in Switzerland, Germany, France and Italy, having been taken there by early Irish missionaries. Whereas in Ireland, many of the older manuscripts appear to have been worn out through extended and heavy use, their counterparts on the Continent were much less prone to the same risk, because once they ceased to be understood, they were rarely consulted.

The earliest Old Irish passages may be the transcripts found in the Book of Armagh and the Cambrai Homily, both of which are thought to belong to the early 8th century. Important Continental collections of glosses from the 8th and 9th century include the Würzburg Glosses (mainly) on the Pauline Epistles, the Milan Glosses on a commentary to the Psalms and the St Gall Glosses on Priscian's Grammar. Further examples are found at Karlsruhe (Germany), Paris (France), Milan, Florence and Turin (Italy). A late 9th-century manuscript from the abbey at Reichenau, now in St. Paul in Carinthia (Austria), contains a spell and four Old Irish poems. The Liber Hymnorum and the Stowe Missal date from about 900 to 1050.

In addition to contemporary witnesses, the vast majority of Old Irish texts are attested in manuscripts of a variety of later dates. Manuscripts of the later Middle Irish period, for instance, such as the Lebor na hUidre and the Book of Leinster, contain texts which are thought to derive from written exemplars in Old Irish now lost and retain enough of their original form to merit classification as Old Irish. The preservation of certain linguistic forms which were current in the Old Irish period may provide reason to assume that an Old Irish original directly or indirectly underlies the transmitted text or texts.
