The Life and Achievements of St. Dominic Loricatus was composed by his friend and admirer, Peter Damianus. See Fleury, Hist. Eccles. tom. xiii. p. 96 - 104. Baronius, A.D. 1056, No. 7, who observes, from Damianus, how fashionable, even among ladies of quality (sublimis generis) this expiation (purgatorii genus) was grown.
