Note 16
From Chapter 42 of the Decline & Fall

Antes eorum fortissimi .... Taysis qui rapidus et vorticosus in Histri fluenta furens devolvitur (Jornandes, c. 5, p. 194, edit. Murator. Procopius, Goth. l. iii. c. 14, et de Edific. l iv. c. 7.)

Yet the same Procopius mentions the Goths and Huns as neighbours to the Danube, (de Edific. l. v. c. 1.)
