St Gildas, the Welsh author of the De Excidio et Conquestu Britanniae, is also credited with the Lorica, or Breastplate, an apotropaic charm against evil that is written in a curiously learned vocabulary; this too probably relates to an education in the Irish styles of Latin.
St Hildegard of Bingen preserves an unusual Latin vocabulary that was in use in her convent, and which appears in a few of her poems; this invention may also be influenced by Hiberno-Latin.
Hisperica is understood as a portmanteau word combining Hibernia, Ireland, and Hesperides, the semi-legendary "Western Isles" that may have been inspired by the Azores or the Canary Islands; the coinage is typical of the wordplay used by these authors.
One usage of Hesperia in classical times was as a synonym for Italy, and it is noticeable that some of the vocabulary and stylistic devices of these pieces originated not among the Irish, but with the priestly and rhetorical poets who flourished within the world dominated ecclesiastically by Rome (especially in Italy, Gaul, Spain and Africa) between the fourth and the sixth centuries, such as Juvencus, Avitus of Vienne, Dracontius, Ennodius and Venantius Fortunatus.
(Thus the very word famen, plural famina – a pseudo-archaic coinage from the classical verb fari, 'to speak' – is first recorded in the metrical Gospels Evangeliorum libri of Juvencus.
The underlying idea, then, would be to cast ridicule on these Roman-oriented writers by blending their stylistic tricks with incompetent scansion and applying them to unworthy subjects.
