Older catalogues give the date as 1537 or 1538 but Ritter's date of 1530 is now accepted. § A treatise on the signs of conception, abortion and obstetrics. It is one of several gynaecological works by Bonacciuoli. His best known work Enneas muliebris a, sex manual written for Lucrezia Borgia, was first printed in 1502 and reprinted in Wolf and Spach, Gynaeciorum (1597) and again in Pineau, De virginitatis notis (1639). There is a brief foreword by Sybold, and at the end of Bonacciuoli's work is printed Aristotle, De indiciis quibus maris a foeminae generatione generatio discernatur. Bonacciuoli (or Buonaccioli in some sources) was professer of medicine at Ferrara from sometime at the end of the fifteenth century. O'Dowd and Philipp note that 'Bonacciuoli gave detailed descriptions of the mons veneris, clitoris and hymen,' presumably this is in Enneas muliebris, but no source is given (Michael J. O'Dowd and Elliot E. Philipp, The history of obstetrics and gynaecology (1994) p. 60).
