As for the author's style, opinions diverge. A judicious and broadly positive assessment such as this was made in 1890 by the American historian and ethnologist Hubert Howe Bancroft:-He rises above the mere monk chronicler and strives to interest his readers by variety of topics, as well as by treatment, which receives no inconsiderable aid from a descriptive power of rare occurrence among his confreres; other faults remain, however. While concise enough in the narrative generally, he abandons himself to inappropriate deviations and wordy argument, and revels in learned references.
