Résumé :
This paper gives a date of around 1290 to Planudes’ reading of Xiphilinos’ Epitome of
Cassius Dio and to the fragments from this text that he included in his Synagoge, as well as in the notes supplementing his exemplar of Cleomedes. We still have the copy of
Xiphilinos used by Planudes, Iviron 812: this is in fact the only witness of Paeanios’
trans lation of Eutropius and of a long fragment from John of Antioch’s Historia chronike.
This miscellaneous codex, copied from the end of the eleventh century and from the
first half of the twelfth (and not from the fourteenth as is usually stated, following Lam -
pros), was annotated by Maximos Planudes and used by Nikephoros Gregoras in the
selection from John of Antioch, Eutropius and Xiphilinos reflected in his notebook,
Palat. Heidelberg. gr. 129. From the middle of the fourteenth century, Gregoras also
annotated Marc. gr. 395, the oldest witness of Cassius Dio, probably preserved at the
Chora Monastery.
