If there is any distinction between the two participants in the _Dialogue_, it is certainly between the one's taste for the evidence of art and the other's penchant for natural beauties. If their opposition is not very conspicuously maintained by Gilpin, it is surely because his own loyalties were divided and were to be reconciled only with some subtlety and ingenuity later in his career. Callophilus, who cites Pope's balanced instructions on the mixture of art and nature (p. 26), is more inclined to appreciate these elements in the garden where Nature's defective compositions have been improved; the love of beauty that his name announces is of beauty methodized, though without exceeding "a probable Nature" (p. 6). On the other hand, his enthusiastic companion, Polypthon, directs his eponymous ill-will mostly against the decorations of art: the "hewn Stone" of Dido's Cave particularly offends him (p. 14), and he "cannot very much admire" the canal below the Rotunda (p. 15). Yet he seems to share Callophilus' notions about "mending" nature (p. 23), and it is he who proposes a landscape that, substituting farm-houses for temples (p. 45), approximates most clearly to that prettiest of eighteenth-century landscape ideas, the _ferme ornee_. Polypthon's predilection for scenery outside gardens seems equally compromised by his ready assent to Callophilus' praise of the carefully studied contrasts in Stowe gardens: so that he may turn from the less agreeable vista down the Queen's Pool and look instead over Home Park, earlier noted for its "rural scene" (p. 8), and now admired as a natural field--though the cattle prominent in Rigaud's drawings[5] are not mentioned. But what is artless for Polypthon is studied by his companion in terms of art: "the Field is _formed_ by that Semi-circle of Trees into a very grand Theatre" (p. 15, _my italics_), and his eye registers an architectural feature--Vanbrugh's Pyramid--as the apt centre of that field of vision. This particular exchange at the Rotunda suggests that the usual modern discussion of landscape gardens in terms of their diminishing formality or escalating informality is less Gilpin's concern than the mind's involvement with the various landscapes. Callophilus and Polypthon can apparently both contemplate the same scene from the Rotunda, southwest towards Kent's Temple of Venus and Vanbrugh's Pyramid, yet adjudge its artifice differently. What is evidently at work in Gilpin's record of this garden is the mental experience of it, and in his case the ambiguities of his visual response.
