Bravo Brad:
Interesting that the print above is French as apparently the origination of the more naturalized "landscape garden" (to later be termed "landscape architecture") emanated pretty much from England and GB from the early 18th century on into the 19th.
The onset of "Romanticism" in landscape planning (perhaps emanating from the painting art of the likes of Lorraine et al) probably saw its first expression in 1725 at Chiswick House by William Kent (client Lord Burlington).
As it later evolved with the landscaping work of Lancelot "Capability" Brown and later Humphrey Repton et al was generally done on a massive scale and that, I think, is necessary for us to know as it later came to be represented in golf course architecture.
But what was the genesis and motivation of this English landscape architecture (landscape gardening back then) that can generally be termed "Romanticism"?
Professor H.W. Janson (author of "The History of Art", the most popular and enduring art history book ever produced) explained it particularly well, in my opinion;
"But this interest in the long-neglected "Gothick" past was symptomatic of a general revulsion against the established social order and established religion---against established values of any sort---that sprang from a craving for emotional experience. Almost any experience would do, real or imaginary, provided it was sufficiently intense. The declared aim of the Romantics, however, was to tear down the artifices barring the way to a "return to Nature"---nature the unbounded, wild and ever changing, nature the sublime and picturesque." (this certainly does smack of some of the sentiments expressed in the later golf architecture articles of Max Behr, doesn't it?
).
Again, we need to remember that this type of massive English landscape gardening or landscape architecture took place originally in the 18th century perhaps at least a century or more before man-made golf course architecture itself began.
Although it was unquestionably a return to naturalism in landscape architecture it was not originally as intensely "naturalized" as the later 19th century expressions that ultimately evolved into such things as Gertrude Jekyll's "English Garden" or "English Cottage Garden" that was generally of smaller scale and very representative of the general "Arts and Crafts" movements of the latter half of the 19th century and early 20th.
So we can see that golf course architecture, certainly in a routing sense at first, was coincidentally and conveniently dropped right into some of those much earlier "English" Landscape architectural designs of the likes of a Capability Brown that were often on a massive scale (perhaps designed over hundreds of acres).
It should also be mentioned that one particularly pertinent label was given to Capability Brown's LA style and that was "Serpentine"----the very type of line and outline that would come to be so often utilized in golf course architecture (both routing and specific architecture feature shape) beginning after the turn of the 20th century.
Interestingly, the common link between the type and style of the early LA designs of a Capability Brown with golf course architecture, particularly INLAND, would come to be known as "parkland" (those early massive English estates where Brown executed his LA were known as "Parks").
