[164] Now Swabia. When the Marcommanni, towards the end of the reign of Augustus, quitting their settlements near the Rhine, migrated to Bohemia, the lands they left vacant were occupied by some unsettled Gauls among the Rauraci and Sequani. They seem to have been called Decumates (Decimated), because the inhabitants, liable to the incursions of the Germans, paid a tithe of their products to be received under the protection of the Romans. Adrian defended them by a rampart, which extended from Neustadt, a town on the Danube near the mouth of the river Altmühl, to the Neckar near Wimpfen; a space of sixty French leagues. [165] Of Upper Germany. [166] The Catti possessed a large territory between the Rhine, Mayne and Sala, and the Hartz forest on this side of the Weser; where are now the countries of Hesse, Thuringia, part of Paderborn, of Fulda, and of Franconia. Learned writers have frequently noted, that what Caesar, Florus and Ptolemy have said of the Suevi, is to be understood of the Catti. Leibnitz supposes the Catti were so called from the active animal which they resemble in name, the German for cat being _Catte_, or _Hessen_. [167] Pliny, who was well acquainted with Germany, gives a very striking description of the Hercynian forest:--"The vast trees of the Hercynian forest, untouched for ages, and as old as the world, by their almost immortal destiny exceed common wonders. Not to mention circumstances which would not be credited, it is certain that hills are raised by the repercussion of their meeting roots; and where the earth does not follow them, arches are formed as high as the branches, which, struggling, as it were, with each other, are bent into the form of open gates, so wide, that troops of horse may ride under them."--xvi. 2. [168] _Duriora corpora_. "Hardier frames;" _i.e._ than the rest of the Germans. At Hist. ii 32. the Germans, in general, are said to have _fluxa corpora_; while in c. 4 of this treatise they are described as _tantùm ad impetum valida_. [169] Floras, ii. 18, well expresses this thought by the sentence "Tanti exercitus, quanti imperator." "An army is worth so much as its general is." [170] Thus Civilis is said by our author (Hist. iv. 61), to have let his hair and beard grow in consequence of a private vow. Thus too, in Paul Warnefrid's "History of the Lombards," iii. 7, it is related, that "six thousand Saxons who survived the war, vowed that they would never cut their hair, nor shave their beards, till they had been revenged of their enemies, the Suevi." A later instance of this custom is mentioned by Strada (Bell. Belg. vii. p. 344), of William Lume, one of the Counts of Mark, "who bound himself by a vow not to cut his hair till he had revenged the deaths of Egmont and Horn."
