Lyon, Johannes Siber ca. 1490. Contemporary leather binding; Large folio [43 x 29 cm]. 269 (of 292) leaves. Rare, well preserved copy of a rare law Incunable. The present volume is the third and final part of Bertachinus's most famous work: Repertorium iuris, which was dedicated to Pope Sixtus IV. This comprehensive legal encyclopedia, first published in Rome in 1481, organizes the rich Italian legal tradition alphabetically, possibly to increase accessibility. Bertachini's approach combines both canonical and civil law, with a preference for the former. The Repertory established a literary genre that became popular during the early modern period, addressing the need for an organized approach to the evolving commentary tradition. Its clarity, depth, and systematic presentation made it.
