These three dictatorships must be dated after the end of Livy's record in Book 10 in 292, and before 284, when a fragment of Fast. Cap. begins. Mommsen suggested 287 for Claudius after the death of Hortensius, but there is no specific evidence. They are listed above at the latest possible date, 285. (Broughton MRR I)
