Being called a "no-brainer horsehit(ter)" by you is like being called a true artist by Picasso. I am hono(u)red!
In historical terms, "dark ages" usually imply some sort of decline from an earlier ideal (i.e. the end of the flourishing of the Indo-European civilisations around the end of the first millenium). How can the period of 1850-1907 be called the "dark ages" of golf course architecture when, as you rightly note, GCA did not really start until 1850? It is this sort of fuzzy/non logic which makes me sceptical of any of your mostly unfounded claims.
I call them "unfounded" becuase I think that you (and I and all others with an interest in GCA) are operating in a real intellectual vaccuum, in that we rely for opinions on what things were like in the "dark ages" to accounts of those did not live for a significant time in those ages, and had virtually no influence on golf or GCA at that time. Why, for example, do we believe what MacKenzie has to say about this period when he spent most of it as a non-golfer, doctor and military man? It is like relying on shadows from fires within a cave to understand what is actually happening in the cave. And, vis a vis "dark ages," do you not think that architects like MacDonald, Tillinghast, MacKenzie and Thomas had a vested interested in calling their era a "golden age?"
The facts are that nobody really knows what sort of GCA was really going on in the 1850-1907 period, because most of the courses built then were at least somewhat over-written to accomodate the Haskell ball. I, for one, have seen no serious discussion as to what that "overwriting" entailed, outside of a few instances (i.e. Muirfield, Dornoch) where you can see the old routings and compare them to the new. In those cases, I think there is ample evidence to show that Old Tom Morris, for example, did some amazing things with the land he was given. The routing and green sites at Dornoch are largely his work, despite substantial alterations and changes over the past 100+ years. I (or any one else) can stand on that course and see the features that Old Tom designed and or found. There is a lot of his work underlying Colt's Muirfield. Much of his work at Lundin/Leven (from which CBM borrowed so many of "his" ideas) still remains.
The answer, young Tom, is in the dirt, and not in the dusty tomes of possibly self-serving writers or very variable quality who, in any case, were not trained historians. Even the best of them, Darwin, was just an essayist, who would have shined on this website, and in popular print, but would never have been able to hold down a chair in architecture at Oxford or Cambridge. Unlike, for example, JakaB.........
From what I can see, on the ground and in the dirt, there was a lot of good, perhaps even "golden" GCA that was produced in the "dark ages." Prove me wrong, if you can, but please don't try to do so just by quoting some slightly older person than you who never took the time to look at the dirt either, or if he did, didn't know what he was looking for.
