Edith Wharton,
The Valley of Decision — Book II, Chapter 10
(1901)
“ It seemed that magnificence could go no farther, till the seventeenth century brought to the throne a Duke who asked himself how a self-respecting prince could live without a theatre, a riding-school and an additional wing to lodge the ever-growing train of court officials who had by this time replaced the feudal men-at-arms. He answered the question by laying an extra tax on his people and inviting to Pianura the great Roman architect Carlo Borromini, who regretfully admitted that his illustrious patron was on the whole less royally housed than their Highnesses of Mantua and Parma. ”
