Perhaps in no other art form were the tensions and transformations in the arts more conspicuous than in landscape gardening. Gilpin is especially rewarding in his instinctive attention to these shifting patterns; although the dialogue form is not very skillfully handled, it yet allows some play between the rival attitudes. Thus his characters attend to both the emblematic and the expressive garden;[3] to both its celebration of public worth and its commendation of private virtue. While Gilpin seems sufficiently and indeed sharply aware of set-piece views in the gardens, the three-dimensional pictures contrived among the natural and architectural features, he also reveals himself as sensitive towards the more fluid psychological patterns, what one might term the _kinema_ of landscape response. Above all, his obvious delight in the landscape garden and appreciation of it vie with an equally strong admiration for scenery outside gardens altogether. At the time of Gilpin's visit, Lord Cobham's gardens were substantially as they are represented in the engravings published in 1739 by the widow of Charles Bridgeman, one of Stowe's designers. In the year of Gilpin's visit work had just started in the northeast part of the grounds upon the natural glade that came to be known as the Grecian Valley.[4] Whether it is the work of Lancelot ("Capability") Brown, who was then a gardener at Stowe, or only prophetic of it, the Grecian Valley was a hint of the less architectural, the more carefully "natural" gardens of the next decades. Although Gilpin would presumably have seen little of this most advanced example of gardening style, he would still have observed what were, in the terms customarily invoked, formal and informal ingredients at Stowe. From the Rotunda, for example, he looked over the (now vanished) Queen's Pool, "laid out with all the Decorations of Art" (p. 15), including the oblong canal itself and various statues; the first body of water encountered beside the Lake Pavillions (p. 4) was octagonally shaped and bore an obelisk at its centre. Yet elsewhere there was frequent occasion to praise prospects that obviously seemed much less artificial.
