The _Germania_ of the Roman historian Tacitus (54-119 A.D.) is a treatise on the manners, customs, and institutions of the Germans of his time. It is one of the most valuable sources of knowledge of the condition of the Germans before the migrations. These sources are mainly of two kinds: the accounts of contemporary writers, chiefly Roman authors; and the documentary sources of the period of the tribal kingdoms, particularly the tribal laws, such as the laws of the Salic Franks (see no. 4), Burgundians, Anglo-Saxons, etc. It will be evident to the student that the sources of both kinds fall short of realizing the needs of historical trustworthiness: the first kind, because the Roman authors were describing institutions and customs which they knew only superficially or from a prejudiced point of view; the second, because the laws and documents of the tribal period reflect a stage of development which had changed considerably from the primitive stage. Conclusions in regard to the conditions of the Germans in the early period are based on the careful criticism of each single document and on a comparison of each with all the others. Some indication of this method is suggested in the notes to nos. 1 and 4. Even at best the results are subject to uncertainty. The _Germania_ of Tacitus is the clearest and most complete of the sources of the first type, but it is not free from obscurity. Since there are numerous editions of it, we have not thought it necessary to refer to any particular one. 5. The land [inhabited by the Germans] varies somewhat in character from one part to another, but in general it is covered with forests and swamps, and is more rainy on the side toward Gaul and bleaker toward Noricum and Pannonia. It is moderately fertile, but not suited to the growing of fruit trees; it supports great numbers of cattle, of small size, however. 6. Iron is not abundant, as appears from the character of the weapons of the inhabitants; for they rarely use swords or the larger spears; instead they carry darts with small, narrow heads, which they call _frameæ_. But these are so sharp and so easily handled that they are used in fighting equally well at a distance and at close quarters.... The number of warriors is definitely fixed, one hundred coming from each district, and the warriors are known by that name [_i.e._, hundred]; so that what was originally a number has come to be a name and a title.{1}
