“ O [Roman] people be ashamed; be ashamed of your lives. Almost no cities are free of evil dens, are altogether free of impurities, except the cities in which the barbarians have begun to live...Let nobody think otherwise, the vices of our bad lives have alone conquered us...The Goths lie, but are chaste, the Franks lie, but are but are generous, the Saxons are savage in cruelty...but are admirable in chastity...what hope can there be [for the Romans] when the barbarians are more pure [than they]?-Salvian ”
