 Sir Roger L'Estrange produced an English translation ("The Guide to Heaven", 1680), later reprinted as "A Guide to Eternity" (London 1900).Shortly after his ordination he collected some of the most beautiful passages in the Church Fathers on the Mass, and later published them in a booklet, which with certain additions grew into his "De Sacrificio Missae".In addition he composed several unpublished works, known as "Ascetici", for the instruction of members of his own order.
