Reverend Charles Watts Whistler MRCS, LSA, (1856-1913) was a writer of historic fiction that plays between 600 and 1100 AD, usually based on early English/Saxon chronicles, Norse or Danish Sagas and archeological discoveries. He studied medicine at St Thomas's Hospital, London, and was a Member of the Royal College of Surgeons and a Licentiate of the Society of Apothecaries. After practicing as a surgeon he was ordained deacon in 1884 and priest in 1885. He then served as a clergyman in a succession of parishes. Whistler was interested in the history of England before the Norman Conquest and this is reflected in the subject matter of his prolific work as a historical novelist.
With regard to the topography of the Wessex frontier involved, although it practically explains itself in the course of the story, it may be as well to remind a reader that West Wales was the last British kingdom south of the Severn Sea, the name being, of course, given by Wessex man to distinguish it from the Welsh principalities in what we now call Wales, to their north. "Prince of Cornwall" takes place around 690-710 AD, and deals much with the relations between Welsh and Saxons, feat. some resident Danes in the country.
