Senones – two distinct groups of ancient people of Gaul – One having settled in NE Italy south of the Po in the 4th cent. B.C; the other lived in the valley of the Seine, and it is the latter that we are interested in here. In Caesar’s time they inhabited the district which now includes the French departments of Seine-et-Marne, Loiret and Yonne. From 53–51 B.C. they were engaged in hostilities with Caesar, brought about by their expulsion of Cavarinus, whom Caesar had appointed their king . In 51 BC a Senonian named Drappes threatened the Provincia, but was captured and starved himself to death. From this time the Gallic Senones disappear from history.
