The parchment codex called Littera Florentina is the closest surviving version of the official Digest of Roman law promulgated by Justinian I in 530–533.
The codex, consisting of 907 leaves, is written in the Byzantine-Ravenna uncials characteristic of Constantinople, but which has recently been recognized in legal and literary texts produced in Alexandria and the Levant as well.
Marginal notes suggest that the codex was in Amalfi, which was part of the Byzantine territory in Italy governed by the Exarchate of Ravenna in the 6th century.
The sudden reappearance of the manuscript in the late eleventh or early twelfth century has been the subject of much debate among legal historians.
