The number of Boethian manuscripts in the Iberian Peninsula is modest compared with those in the British Isles and Italy, partly, perhaps, because of the Arab domination there; the oldest manuscripts come from Ripoll in Catalonia, which was always under Christian control. The Portuguese manuscripts contain five Boethian items, the Spanish, 153, of which the De Consolatione Philosophiae occurs most often. Some of these manuscripts are of exceptional quality, and many of them include extensive glosses.
