In that fortunate hour of English history, when the cruel sights and haunting insecurities of the Middle Ages had passed away, and while, as yet, the fanatic zeal of Puritanism had not cast its blighting shadow over all merry and pleasant things, it seemed good to one Denzil Calmady, esquire, to build himself a stately red-brick and freestone house upon the southern verge of the great plateau of moorland which ranges northward to the confines of Windsor Forest and eastward to the Surrey Hills. And this he did in no vainglorious spirit, with purpose of exalting himself above the county gentlemen, his neighbours, and showing how far better lined his pockets were than theirs. Rather did he do it from an honest love of all that is ingenious and comely, and as the natural outgrowth of an inquiring and philosophic mind. For Denzil Calmady, like so many another son of that happy age, was something more than a mere wealthy country squire, breeder of beef and brewer of ale. He was a courtier and traveler; and, if tradition speaks truly, a poet who could praise his mistress's many charms, or wittily resent her caprices, in well-turned verse. He was a patron of art, having brought back ivories and bronzes from Italy, pictures and china from the Low Countries, and enamels from France. He was a student, and collected the many rare and handsome leather-bound volumes telling of curious arts, obscure speculations, half-fabulous histories, voyages, and adventures, which still constitute the almost unique value of the Brockhurst library. He might claim to be a man of science, moreover-of that delectable old-world science which has no narrow-minded quarrel with miracle or prodigy, wherein angel and demon mingle freely, lending a hand unchallenged to complicate the operations both of nature and of grace-a science which, even yet, in perfect good faith, busied itself with the mysteries of the Rosy Cross, mixed strange ingredients into a possible Elixir of Life, ran far afield in search for the Philosopher's Stone, gathered herbs for the confection of simples during auspicious phases of the moon, and beheld in comet and meteor awful forewarnings of public calamity or of Divine Wrath.
