Irish and Anglo-Saxon writing

The half-uncial hand was introduced in Ireland along with Latin culture in the 5th century by priests and laymen from Gaul, fleeing before the barbarian invasions. It was adopted there to the exclusion of the cursive, and soon took on a distinct character. There are two well established classes of Irish writing as early as the 7th century: a large round half-uncial hand, in which certain majuscule forms frequently appear, and a pointed hand, which becomes more cursive and more genuinely minuscule. The latter developed out of the former. One of the distinguishing marks of manuscripts of Irish origin is to be found in the initial letters, which are ornamented by interlacing, animal forms, or a frame of red dots. The most certain evidence, however, is provided by the system of abbreviations and by the combined square and cuneiform appearance of the minuscule at the height of its development. The two types of Irish writing were introduced in the north of Great Britain by the monks, and were soon adopted by the Anglo-Saxons, being so exactly copied that it is sometimes difficult to determine the origin of an example. Gradually, however, the Anglo-Saxon writing developed a distinct style, and even local types, which were superseded after the Norman conquest by the Carolingian minuscule. Through St Columbanus and his followers, Irish writing spread to the continent, and manuscripts were written in the Irish hand in the monasteries of Bobbio Abbey and St Gall during the 7th and 8th centuries.
