The Royal Navy was Henry's creation, and it saved both himself and his daughter after him when they adopted an island policy and defied the Catholic powers of Europe. Wolsey had no notion of the importance of sea power to England. He was a great medieval churchman, a civil servant of the old school, and a diplomatist of the Renaissance type. But of the future development of England at home and on the sea Wolsey had no vision at all. His master, with that curious instinct of oneness with the English people which was the secret of Tudor greatness, saw deeper. He could use Wolsey's consummate administrative powers during the years of his own apprenticeship in statecraft, and then pass over him along a path of his own which no Cardinal could be expected to tread.
