Gilpin's attention to his characters' intellectual and emotional reactions illuminates the roles of poetry and painting that have always been associated with the rise of the English landscape garden.[10] If Milton's description of the Garden of Eden, so frequently invoked by eighteenth-century gardenists, implied an informal structure for designers to emulate, it equally encouraged associationist activity in gardens. The visual reminders of literary texts at Stowe--_Il Pastor Fido_ (pp. 2ff) or Spenser (pp. 6-7)--which are sometimes accompanied by inscriptions which articulate the "dumb poetry" of the decorations (e.g., p. 13) serve mainly to provoke the imagination of visitors. Sometimes, as at the Hermitage, Stowe's designers force specific associations upon the mind; elsewhere they are content to manipulate the feelings in such a way as to stimulate merely general fancies to which the visitor himself must put whatever name he wishes. It is consistent with Gilpin's attempt to identify Polypthon with the less public aspects of Stowe that it is he who twice formulates his own responses to a scene: the quotations from Milton (pp. 10 and 52-3) may both describe the formal features of landscape, but they are also expressive of his emotional reactions. Pictures, too, provided associationist focus when recalled in a garden: the most obvious instance being the probable allusion to Claude at Stourhead.[11] Yet the actual influence of pictures on landscape gardens has been generally exaggerated.[12] Where they were perhaps a force seems to have been in articulating the mental and emotional reaction of visitors. When Walpole praises William Kent for realizing in gardens "the compositions of the greatest masters in painting",[13] I suspect that he is in part rationalizing his own associationalist instinct, when at Hagley he was reminded of Sadeler's prints or of the Samaritan woman in a picture by Nicolas Poussin. Allusions to pictures were a means of focusing evanescent mood. Gilpin, too, organizes his characters' responses in pictorial focus. The _Advertisement_ again alerts the reader to these studied painterly aims. Once inside the gardens Callophilus sees pictures everywhere: variously disposed objects "make a most delightful Picture" (p. 14), while on at least three occasions in the first half-dozen pages the ruins, prospects, and "Claro-obscuro" of trees are discussed in terms that suggest how his habits of vision have been educated in front of painted or engraved landscapes which in their turn are recalled to provide a suitable vocabulary for his experiences.[14] Even Polypthon invokes the syntax of painting (pp. 25 and 41) to formulate his reactions to scenery.
