Aristoteles Master-piece, or, The Secrets of Generation displayed in all the parts thereof [Aristotle's Masterpiece]

First edition of Aristotle's Masterpiece, "the most popular book about women's bodies, sex, pregnancy, and childbirth in Britain and America from its first appearance in 1684 up to at least the 1870s" (Treasures, Library Company of Philadelphia).

Aristotle's Masterpiece—neither by Aristotle nor a masterpiece—is "the first sex manual written in English" (Norman). The work documents theories and practices of human reproduction during the early modern period. This first edition was assembled in part from excerpts of existing midwifery books, primarily Levinus Lemnius's The Secret Miracles of Nature (1658) and Jacob Rueff's The Expert Midwife (1658). The book's pseudo-Aristotle attribution both lent it an aura of credibility and hinted at the sexual nature of its contents. After the publication of a book called Aristotle's Problems in 1595, which included a few explicit discussions of sex, the name 'Aristotle' came to euphemistically indicate sexual knowledge to an early modern audience.

Unlike medical texts on similar subjects, the book was intended for a vernacular readership and was widely disseminated in Britain and America. It was eventually published in hundreds of editions in at least three versions, each appropriating and combining text from existing works. On average, an edition of the Masterpiece was published every year for 250 years. It was still for sale in London's Soho sex shops as late as the 1930s.

The book's title page—promising "a word of Advice to both Sexes in the Act of Copulation"—speaks to the sexual knowledge offered within. Aristotle's Masterpiece emphasizes both male and female partners' enjoyment of the act. The book's attention to pleasure was essential to its focus on procreative sex within marriage. Underpinning the Masterpiece is the theory that a woman must "cast forth her Seed to commix with the Man (which imploys a willingness in her to be a Copartner in the Act)" in order to conceive. With female and male partners playing an equally active role in "casting forth their seed," both partners' arousal and enjoyment was crucial to reproduction. Thus, women's sexual appetite was accepted as a natural part of life, and the onset of menstruation credited with "[inciting] their Minds and Imaginations to Venery." This first edition concludes with "a word of advice to both sexes in the time of copulation," imparting to its readers a final lesson on the importance of foreplay:

"[A husband] must entertain [his wife] with all kind of dalliance, wanton behaviour, and allurements to Venery but if he perceive her to be slow and more cold, he must cherish, embrace, and tickle her … that she may take fire and be in flames to venery, for so at length the womb will strive and wax fervent with a desire of casting forth its own seed."
This is an especially appealing example of a landmark book in the history of women's health, reproduction, and sex.
