Germania (book) - Purpose and Sources

Purpose and Sources

Ethnography had a long and distinguished heritage in classical literature, and the Germania fits squarely within the tradition established by authors from Herodotus to Julius Caesar. Tacitus himself had already written a similar—albeit shorter—essay on the lands and tribes of Britannia in his Agricola (chapters 10–13). The work can appear moralizing at points, perhaps implicitly comparing the values of Germanic tribes and those of his Roman contemporaries, although any direct comparison between Rome and Germania is not explicitly presented in the text. In writing the work, Tacitus might have wanted to stress the dangers that the Germanic tribes posed to the Empire.

Tacitus' descriptions of the Germanic character are at times favorable in contrast to the opinions of the Romans of his day. He holds the strict monogamy and chastity of Germanic marriage customs worthy of the highest praise, in contrast to what he saw as the vice and immorality rampant in Roman society of his day (ch. 18), and he admires their open hospitality, their simplicity, and their bravery in battle. All of these traits were highlighted perhaps because of their similarity to idealized Roman virtues. One should not, however, think that Tacitus' portrayal of Germanic customs is entirely favorable; he notes a tendency in the Germanic people for what he saw as their habitual drunkenness, laziness, and barbarism, among other traits.

The ethnonym Germanii as used by Tacitus does not necessarily coincide with the modern linguistic definition of Germanic peoples as any people speaking a Germanic language, and the details of the classification Germanii have been debated in scholarship, e.g. the possibility that the Batavians may therefore have been Celtic-speaking. Tacitus nevertheless shows no lack of precision in stating that the Nervii are not actually Germanic as they claim to be. (Ch. 28) He also notes in Chapter 43 that a certain tribe called the Cotini actually speaks a Gallic tongue, and likewise the Osi speak a Pannonian dialect.

Tacitus himself had never travelled in the Germanic lands; all his information is second-hand at best. Ronald Syme supposed that Tacitus closely copied the lost Bella Germaniae of Pliny the Elder, since the Germania is in some places outdated: in its description of the Danubian tribes, says Syme, "they are loyal clients of the Empire. . . . Which is peculiar. The defection of these peoples in the year 89 during Domitian's war against the Dacians modified the whole frontier policy of the Empire." (p. 128). While Pliny may have been the primary source, scholars have identified others; among them are Caesar's Gallic Wars, Strabo, Diodorus Siculus, Posidonius, Aufidius Bassus, and numerous non-literary sources: presumably based on interviews with traders and soldiers who had ventured beyond the Rhine and Danube borders, and Germanic mercenaries in Rome.
