EXCERPT:In the days of the Gauls, Amiens, then known as Samarobriva, or “Bridge over the Somme,” was the capital of the Ambiani, a tribe of Belgian origin. Later it passed under Roman domination, and in the fifth century under that of the Franks. Christianity was first preached there at the beginning of the fourth century, by St. Firmin, first bishop and martyr of Amiens. After the death of Charlemagne, the town became the property of the counts and bishops. The latter were unable to defend it against the Normans, who ravaged it on several occasions. In 1185, it was annexed to the royal dominions, under Philippe Auguste. On account of its position, between Paris and the sea, Amiens acquired great importance at that time, and became the store-house for all the goods sent down the river Somme for distribution over the whole of northern France. The manufacture of cloth and linen, and the preparation of “woad” (vegetable dye-stuff used on a very large scale in the Middle Ages) caused Amiens to become as rich and flourishing as the Flemish towns.
