Two interesting texts from a historical standpoint. The style takes some getting used to, especially Roper's. There is a lot of content that is of little interest to someone who isn't studying the period but the prose style and the different cultural outlook is fascinating. It's like reading a book from another world.
Cavendish uses the "Fall of Princes" genre to tell us about Wolsey's life. He draws on a lot of ideas I found familiar after reading Chaucer like Fortune's Wheel and the folly of worldly aspirations. Roper depicts Thomas More as a modern saint, happy to die as a martyr for the sake of a unified Church and the ideals of the impartial Law. The pomp of Wolsey's ostentatious state rituals is contrasted by Roper I in depicting More'senial and eschewal of worldly riches.
The works aren't literary masterpieces but they do provide an insight into the culture of the time and they are occasionally funny (mostly unintentionally):
"The Bishop of Carlisle, being with him in his barge, said unto him, wiping the sweat from his face, "Sir," quod he, "it is a hot day". "Yea," quod my Lord Cardinal, "if ye had been as well chafed as I have been within this hour, ye would say it were very hot".
And there a few bad-ass moments, like when Wolsey politely rebukes Henry VIII:
"I pray you show his majesty from me that I most humbly desire his Highness to call to his most gracious remembrance that there is both heaven and hell."
