The Merryland books were a genre of English 17th and 18th century erotic fiction in which the female body was described in terms of a topographical metaphor derived from a pun on Maryland.
Stretzer's book was typical of the genre in depicting the female body as a landscape that men explore, till, and plow.
Sometimes, the metaphor of female form equals landscape changes, but the objectification of the female body remains intact; only the image is changed, as when, for example, in another passage, the novel's narrator, Roger Pheuquewell, describes the uterus ("Utrs," as the author simply contracts vowels without graphical indication) as resembling "one of our common pint bottles, with the neck downwards."
Similarly, in Charles Cotton's Erotopolis: The Present State of Bettyland, the female body is an island farmed by men.
The last book in the genre is a parody of Laurence Sterne's A Sentimental Journey Through France and Italy (1768) entitled La Souriciere.
