AUGUSTINUS, Aurelius (354-430). De trinitate. [Strasbourg: Printer of Henricus Ariminensis Type 1 (Heinrich Eggestein), not after 1474.]

First edition of Augustine's treatise on the mystery of the Trinity. Prior to Augustine, much of the serious writing on Christian theology was produced in Greek and reliant on a fossilized system of philosophical jargon. Nowhere was precision of language so important as discussions of the Trinity, disagreements over which caused The Great Schism (and produced many a heresy). Augustine brought a fresh treatment of these discussions to the Latin-speaking world, which his influence has dominated ever since. Kurt Ohly (Gutenberg-Jahrbuch 1956, 1957) identified the books printed in this eponymous shop with Georg Reyser, but that identification probably extends to books printed in type 3 only. Type 1 may have been used in the shop of Eggestein, where it appears as a heading type in his Ludolphus de Saxonia (Goff L-337).
