Howlett charts a tradition of thought and composition from the fifth century to the thirteenth, from the Romano-British writers Pelagius, St Patrick, and Faustus of Riez through a series of prose and verse inscriptions on stone to Gildas, Moucan, the author of the 'Historia Brittonum', the source of the Arthurian legend, Asser, the teacher and biographer of Alfred the Great, the hagiographers Rhygyfarch ap Sulien of Llanba-darn Fawr, Lifris and Caradog of Llancarfan, and finally to Geoffrey of Monmouth and Gerald of Wales, who presented Welsh traditions of Patrick, David, Arthur, and Merlin, of storytelling and music, to a wider European audience.
The sophistication of this literature proves that the Welsh never endured a 'Dark Age', maintaining Latin culture throughout the period in which it was lost elsewhere. The encoded signatures, infixed dates, invective, wit, word play, and architectonic brilliance reveal the Welsh in two aspects, as unique transmitters of a tradition of Latin unbroken from Roman times to the present, and as tutors who laid foundations for the most spectacular literary achievements of their neighbours in Irish, English, and French.
