This commentary was assembled by Rev. George Leo Haydock (1774-1849) and published as notes to the Douay-Rheims translation of the Bible in numerous editions between 1811 and 1859. The 1859 edition has remained in print until the present, an indication of the work’s continuing importance. It is primarily an assemblage of sayings of the fathers and of medieval exegetes and theologians, but includes more modern interpretations. Haydock’s commentary is widely considered a Catholic classic which directly and accurately expresses the Church’s traditional interpretation of biblical passages.
