ZACHARIAS CHRYSOPOLITANUS. Unum ex quattuor seu Concordantia evangelistarum. STRASSBURG, CW Printer, 1473. In-folio. (398 x 280 mm). 182 leaves. Illuminated and rubricated copy. Early XIXth century binding.
First edition of the only known text of the medieval scholar Zacharias Chrysopolitanus (id est “Besançon”). He succeeded in building a concordance between all four different Gospels, displaying extraordinary learning. He alludes too to some knowledge of his maverick contemporary, Peter Abelard. One of the very rare known examples of a colophon in Arabic numerals. Of great rarity (no copy in Rare Book Hub and ABPC).
