Most of the details about the life of Henry Fitzalan, fourteenth Earl of Arundel, come from a biography written in 1580, which was the year of his death, by a close associate, probably his private chaplain, who had clearly been an eyewitness to most of the events described. The latter wrote the essay for the benefit of the Earl's two daughters and heiresses, “for the perpetual memory of a personage very honorable, and that ye who shall remain of his blood may the rather rejoice in so noble a progenitor.” Since this was his purpose, there can be little doubt that the author has a tendency to stress the virtues and successes of his subject, and to gloss over his defects and omit his failures. What is recorded, however, carries the ring of truth, and the selectivity of the presentation throws light on the values and actions which the author considered important and praiseworthy.
The Earl of Arundel was no ordinary nobleman. He was the representative of the most senior and one of the richest and most powerful aristocratic families in the country. He was a man who inherited vast estates and equally vast authority in his native Sussex, and who lived in a style appropriate to his position. Unlike the more modern-minded nobles, he does not seem to have been much affected by the educational reforms of the Renaissance. When on embassies abroad, he certainly confined himself to speaking English, and it seems possible that he lacked the skill to do anything else.
