BELGIUM, manifestly distinguished from Belgica, as a part from the whole (Cæsar); who makes Belgium the country of the Bellovaci; Hirtius adding the Atrebrates. But as the Ambiani lay between the Bellovaci and Atrebrates, we must also add these: and thus Belgium reached to the sea, because the Ambiani lay upon it: and these three people constituted the proper and genuine Belgæ (all the rest being adventitious, or
foreigners); and these were the people of Beauvais, Amiens, and Artois.
