Link 2. Germaniae, an unusual expression, perhaps analogical to Gallias (I. 8. 4 n.), but found also in 23. 2 of free Germany beyond the Rhine. But Galliae means the three Gallic provinces, and this can hardly mean Germania Superior and Inferior.
19. veteranas cohortis. Besides the Tungrians in 16. 12, he already counts on the eight Batavian cohorts at Mogontiacum, although their revolt is not described until ch. 19. Münzer, 89, gave this as an example of the misleading nature of T.'s source; but the passage is part of Civilis' speech.
21. multos . . . ante tributa genitos, certainly an absurd exaggeration, if we date the tribute at latest to the census of 27 bc (Dio LIII. 22. 5). Compare Aper's story in Dial. 17. 4, of the old man encountered in Britain (in ad 43?) who claimed to have fought against Caesar 97 years earlier.
