Résumé :
On the Druckvorlage of the Aldine Edition of Plato ! The manuscript preserved in the private library
of the Marquis de Rosanbo at Château de Rosanbo (Lanvellec) in Brittany, catalogued in 1737
as No. 283 in the Le Peletier / Pithou collection, can be identified as the model of the Plato Aldine
printed in 1513. It contains fragments of Cratylus and Phaedo copied by scribe A, who also numbered
the extant quires in Phaedo, and fragments of Laws and Epinomis, copied by scribe B (similar to Johannes
and Manuel Gregoropulos). Scribe A copied from Paris. gr. 1811 possibly before 1506 and
corrected the text in scribendo, Aldus Manutius and Markos Musuros revised it against Marc. gr. Z.
186. Scribe B copied from the Bessarion manuscript Marc. gr. Z. 187 while Manutius and Musuros
corrected the text with Marc. gr. Z. 188, making fewer and less careful corrections compared to the
dialogues copied by scribe A. Considering the remaining foliation and the reconstructed extent of the
preserved dialogues in Rosanbo 283 as well as the content of both source manuscripts Paris. gr. 1811
and Marc. gr. Z. 187, it is possible that scribes A and B copied their exemplars into two separate
manuscripts at different times.
