A rare copy of Aristotle's Masterpiece (1684), a 17th century sex manual, will be offered for auction in London on March 2.
The writer of the book was not Aristotle, although they purported to be the philosopher as he was viewed as an expert on reproduction.
The work is filled with erotic illustrations and tips for the bedroom, including advice on how to conceive a boy or how to avoid becoming pregnant.
It's expected to make £10,000-15,000 ($14,531-21,797) at Dominic Winter Auctions. Another specimen sold for £22,500 ($32,695) at Bonhams in 2014.
