'Overall, this is a varied and interesting set of papers that does justice to the range of Boyle's own interests, and the personal reflections that finish the volume give the reader a sense of the man as well as the scholar.' Journal of Ecclesiastical History ’Unlike most memorial volumes, Omnia disce contains not only learned articles but also personal reminiscences of Fr Boyle by some of his scholarly friends, and even a hitherto unpublished paper by the dedicatee. ... This is a different sort of memorial volume, and the better for that. Adding to its richness are 34 illustrations, including a photograph of a smiling Fr Boyle in the cortile of San Clemente, his arms uplifted and his eyes raised to the heavens. This volume would give him much to smile about.’ English Historical Review
