Montesquieu

Peoples who do not till the land do not have the same notion of luxury. Just consi­der, in Tacitus, the admi­ra­ble sim­pli­city of the Germanic peo­ples : the arts did not fashion their orna­ments, they found them in nature. If their chief’s family nee­ded to be dis­tin­gui­shed by some sign, it was in that same nature that they had to find it : for the kings of the Franks, the Burgundians, and the Visigoths, their long hair was their dia­dem.
