Videro il mar scoprir sotto a Girona Ne lo smontar giù de i montani dorsi; E, costeggiando a man sinistra il lito, A Barcellona andâr pel camin trito.

Feron camin diverso i cavallieri, Di quà Zerbino, e di là il Conte Orlando.

About the time when "Ragallac son of Uatac was pierced on the back of a white steed," Saint Camin in his island school at Inis Caltra, where red mountains hem in Lough Derg of the Shannon, was writing his Commentary on the Psalms, recording the Hebrew readings on the margin of the page.

A few years before that battle, in 634, Saint Cummian of Durrow, some thirty miles to the east of Camin's Holy Island, wrote to his brother, the Abbot of Iona in the northern seas, quoting Latin writers sacred and secular, as well as Origen, Cyril and Pachomius among the Greeks.
