The characteristic traits of the Arroyo Beatus make it unique amongst all other beatus codices. It is considered to be a late beatus that combines two features: its images contain high Romanesque formulae and elements reminiscent of the illustrative tradition of early medieval beatus codices, emphasising its ability to enlighten and convey God’s message more effectively than words. In addition, this codex heralds in a return to the visual bases of classicism. The stylistic similarities between the Arroyo Beatus and the Cardeña Beatus suggest that it may have been illustrated in the San Pedro de Cardeña Monastery. The manuscript was given to the San Andrés de Arroyo Cistercian Monastery where it was safeguarded by the monks in charge until it was acquired from M. Toca in 1882 by the Bibliothèque nationale de France, where it remains to the present day.
