Henry William Carless Davis, 1911 Encyclopædia Britannica, Volume 11… (1911)
“ We know nothing of his life beyond what may be gathered from his own writings. Their evidence suggests that he died in or shortly after 1210, and that he had resided almost continuously at Canterbury from the time of his admission. The only office which we know him to have held is that of sacrist, which he received after 1190 and laid down before 1197. He took a keen interest in the secular quarrels of the Canterbury monks with their archbishops, and his earliest literary efforts were controversial tracts upon this subject. ”
