Calcidius
Digby 23
Digby 23 is the name given to a manuscript in Oxford’s Bodleian Library that was bequeathed to Osney Abbey, near Oxford, by Master Henry of Langely (died circa 1263).
This 12th century document contains The Song of Roland (La Chanson de Roland) as well as a copy of the Latin translation of Plato’s Timaeus by Chalcidius. Now the Digby 23 Project makes the entire codex available on line(a) and should be most useful to serious researchers.
