A review by the_games_a_foot
The Life of Merlin by Geoffrey of Monmouth, Basil Fulford Lowther Clarke

Did not finish book. Stopped at 5%.
Geoffrey of Monmouth has a severe dislike of Merlin. He has passages that make Merlin seem a great man, stable, and a wise leader and in the next sentence and for paragraphs he is then a raving lunatic with little to no explanation or growth. 

Maybe it is the writing style.
Maybe it is the fact that Monmouth is a Christian and I am a Pagan.
Maybe it is the fact that Monmouth and I are separated by hundreds (thousands) of years of Merlinian and Arthurian scholarship.
