First editions of three very curious and rare books on marriage and sex bound together in one volume.
Ad 1: In this curious work, including - according to the title-page - the Vroycke Uyren (which contain Neyn's poetical work with separate signatures and pagination and also published separately, see ad 2) Pieter de Neyn describes the marriage customs of all parts of the world, pages 171-230 being devoted to Africa including ten pages of original matter concerning the Hottentots; pp. 231-65 are on America. The text is partly based upon his own interviews with the natives, when the author was in the service of the V.O.C., the Dutch East India Company, at the Cape of Good Hope and Batavia and is illustrated by the well-known artist and book illustrator Jan Luyken. The author tells his readers how he often tried to make the Hottentots talk to him, encouraging them with tobacco and brandy. He got also much information, De Neyn informs his readers, from another traveller, a certain Dirk Beekman. According to Theal (History of Africa 1486-1691) Neyn was 'a good-natured, witty personage, well read in law and thoroughly competent for his post': he 'held the office of Fiscal at the Cape from 1672 to 1674', after which he was depatched to Batavia.
The work is dedicated to Jacob van Sander, burgomaster of Hoorn and is preceded by laudatory poems by J. Vollenhove, S. Bosch and H. Hinchlif Zwart  A second edition appeared in 1697 and several editions followed in the eighteenth century, without the Vrolyke Uuren.
Ad 2: The collected poems of Pieter de Neyn were also published separately, containing poems on public figures like Jacob Westerbaan, Blasius, Rombout Verhulst, Michiel de Ruyter, Hendrik Hooft, etc., a few referring to South Africa, among others on the Robbeneiland, and witty love poems.  
Ad 3: This work is even more curious than the other two. It was originally written in French by Nicolas Venette (1622-1698), professor anatomy in La Rochelle, under the pseudonym 'Salocini Venetien', and published in the same year 1687 with the title Tableau de l'amour consideré dans l'estat de mariage in 'Parma' which undoubtedly must have been Amsterdam, with re-editions in 1688, 1689 and 1691; it was republished in Paris and London till far into the nineteenth century. The present Dutch translation/adaptation (possibly by the publisher Timotheus van Hoorn) was also republished several times: the third edition appeared in 1688, the sixth in 1701 and even an eleventh in 1781 (with a re-issue in 1797). The work deals with all aspects of sex: virginity, impotence, fertility, how to promote or temper one's lust, sexual diseases and how to cure them, white magic and bewitchment (which is contested by the author!), etc. It is a strange, but apparently successful and profitable mixture of sex education and pornography.  
Good copies, with the bookplate of Mr. W.C. Baert de Waarde.First leaves slightly frayed at outer margins.

3.　(VENETTE, Nicolas).

Venus minsieke gasthuis, waer in beschreven worden de bedryven der liefde in den staet des houwelijks, met de natuurlijke eygenschappen der mannen en vrouwen, hare siekten, oirsaken en genesingen. Door I. V. E. Medicinae doctor.
Amsterdam, Timotheus ten Hoorn, 1687. 8vo. Full contemporary vellum. With engraved frontispiece depicting a ward in a hospital, dated 1687 by Joseph Mulder. (28), 654, (28) pp.             \580,000

Rare first edition of the Dutch translation of this very popular work. The contents take a position somewhere between sexual education and pornography. The initials on the title are fake. In the preface of the French original, which was first published not long before and of which a French edition was published in Amsterdam by Jean et Gilles Janson a Waesberge in the same year, the author is refered to as 'Mons. Salocini Venetien', which is a conversion of the real name of the author: Nicolas Venette. The well-known French title was La génération de l'homme ou tableau de l'amour conjugal. the book was immensely popular is proven by the fact that the printer Timotheus ten Hoorn  - who was perhaps also the translator - in 1688 already was able to print the third edition followed by at least 12 editions till the end of the eightteenth century. In the last two decades of the seventeenth century more works on sexual education and venereal diseases were published by this printer. The book provides a very interesting glimpse of seventeenth century sexual behaviour.
Good copy with ownership's entry of H.J. Satin (?) in the lower margin of the frontispiece.Frontispiece somewhat soiled.
