Froude's narrative sets out with the marriage of Anne Boleyn.

Here the reviewer plants his first arrow.
The divorce was a nullity, having no authority higher than Cranmer's.

Anne Boleyn, as is likely enough from other causes, was never the King's wife, and Elizabeth was illegitimate, though she had of course a Parliamentary title to the throne.

It seems clear, however, that inasmuch as Katharine had been his brother Prince Arthur's wife, the King could not lawfully marry her, according to the canons of the Catholic Church.

Why did he marry Anne Boleyn?
The reviewer says because he was in love with her, and triumphantly refers to the King's letters, printed in the Appendix of Hearne's Ayesbury.* They are undoubtedly love-letters, and they contain one indelicate expression.
