On Celtic Britain

Reges habet Britannia, sed tyrannos; iudices habet, sed impios; saepe praedantes et concutientes, sed innocentes; uindicantes et patrociniantes, sed reos et latrones; quam plurimas coniuges habentes, sed scortas et adulterantes; crebro iurantes, sed periurantes; uouentes, sed continue propemodum mentientes; belligerantes, sed ciuila et iniusta bella agentes; per patriam quidem fures magnopere insectantes, sed eos qui secum ad mensam sedent non solum amantes sed et munerantes; eleemosynas largiter dantes, sed e regione inmensum montem scelerum exaggerantes; in sede arbitraturi sedentes, sed raro recti iudicii regulam quaerentes; innoxios humilesque despicientes, sanguinarios superbos parricidas commanipulares et adulteros dei inimicos, si sors, ut dicitur, tulerit, qui cum ipso nomine certatim delendi erant, ad sidera, prout possunt, efferentes; uinctos plures in carceribus habentes, quos dolo sui potius quam merito protuerunt catenis onerantes, inter altaria iurando demorantes et haed eadem ac si lutulenta paulo post saxa despicientes.  De Excidio et Conquestu Britanniae, Sanctus Gildas Sapiens

Britain has kings but they are tyrants; she has judges but they are impious, often plundering and assailing, but only the innocent; they avenge and protect, but only the guilty man and the thief; many of them have wives, but they are all whores and adulteresses; swearing they forswear, making vows they lie in the next breath; they make war, but the only battles they rush into are civil and unjust; for certain they chase after thieves throughout the land, but those thieves who sit with them at table they not only love but even remunerate; they dispense alms liberally but they heap up a huge mountain of crimes; they sit in the seat of authority but rarely seek the rule of right judgment; they despise the innocent and humble and are close companions of the bloodthirsty, and the proud, and parricides, and the adulterous enemies of God, acclaiming to the stars, if chance so offers, all those who ought, together with their very name, be exterminated; they have many subdued in their prisons, those who more by deceit than by justice bear the burden of chains; in oath taking they linger among the altars, and shortly afterwards look on them with contempt as if they were filth stained stones. On The Destruction and Ruin of Britain, Saint Gildas the Wise
