 The other king of the Eburones, Cativolcus, killed himself "with the juice of the yew-tree, of which there is a great abundance in Gaul and Germany".The name "Eburones" (like other similar Celtic-based tribal names around Europe) is based on the Celtic word for the yew tree, and this might also be true of the later Toxandri.Under the Romans, for example in the time of Augustus, the Tungri "civitas" was at first considered to be a part of Gallia Belgica.
