John Riddle uncovers the obscure history of contraception and abortifacients from ancient Egypt to the seventeenth century with forays into Victorian England—a topic that until now has evaded the pens of able historians.

Riddle’s thesis is, quite simply, that the ancient world did indeed possess effective (and safe) contraceptives and abortifacients. The author maintains that this rich body of knowledge about fertility control—widely held in the ancient world—was gradually lost over the course of the Middle Ages, becoming nearly extinct by the early modern period. The reasons for this he suggests, stemmed from changes in the organization of medicine. As university medical training became increasingly important, physicians’ ties with folk traditions were broken. The study of birth control methods was just not part of the curriculum.

In an especially telling passage, Riddle reveals how Renaissance humanists were ill equipped to provide accurate translations of ancient texts concerning abortifacients due to their limited experience with women’s ailments. Much of the knowledge about contraception belonged to an oral culture—a distinctively female-centered culture. From ancient times until the seventeenth century, women held a monopoly on birthing and the treatment of related matters; information passed from midwife to mother, from mother to daughter. Riddle reflects on the difficulty of finding traces of oral culture and the fact that the little existing evidence is drawn from male writers who knew that culture only from a distance. Nevertheless, through extraordinary scholarly sleuthing, the author pieces together the clues and evaluates the scientific merit of these ancient remedies in language that is easily understood by the general reader. His findings will be useful to anyone interested in learning whether it was possible for premodern people to regulate their reproduction without resorting to the extremities of dangerous surgical abortions, the killing of infants, or the denial of biological urges.

For 1,600 years Dioscorides (ca. AD 40–80) was regarded as the foremost authority on drugs. He knew mild laxatives and strong purgatives, analgesics for headaches, antiseptics for wounds, emetics to rid one of ingested poisons, chemotherapy agents for cancer treatments, and even oral contraceptives. Why, then, have his works remained obscure in recent centuries? Because of one small oversight (Dioscorides himself thought it was self-evident): he failed to describe his method for organizing drugs by their affinities. This omission led medical authorities to use his materials as a guide to pharmacy while overlooking Dioscorides' most valuable contribution—his empirically derived method for observing and classifying drugs by clinical testing.

Dioscorides' De materia medica, a five-volume work, was written in the first century. Here revealed for the first time is the thesis that Dioscorides wrote more than a lengthy guide book. He wrote a great work of science. He had said that he discovered the natural order and would demonstrate it by his arrangement of drugs from plants, minerals, and animals. Until John M. Riddle's pathfinding study, no one saw the genius of his system. Botanists from the eighteenth century often attempted to find his unexplained method by identifying the sequences of his plants according to the Linnean system but, while there are certain patterns, there remained inexplicable incoherencies. However, Dioscorides' natural order as set down in De materia medica was determined by drug affinities as detected by his acute, clinical ability to observe drug reactions in and on the body. So remarkable was his ability to see relationships that, in some cases, he saw what we know to be common chemicals shared by plants of the same and related species and other natural product drugs from animal and mineral sources.

Western European and Islamic medicine considered Dioscorides the foremost authority on drugs, just as Hippocrates is regarded as the Father of Medicine. They saw him point the way but only described the end of his finger, despite the fact that in the sixteenth century alone there were over one hundred books published on him. If he had explained what he thought to be self-evident, then science, especially chemistry and medicine, would almost certainly have developed differently. In this culmination of over twenty years of research, Riddle employs modern science and anthropological studies innovatively and cautiously to demonstrate the substance to Dioscorides' authority in medicine.

In Contraception and Abortion from the Ancient World to the Renaissance, John M. Riddle showed, through extraordinary scholarly sleuthing, that women from ancient Egyptian times to the fifteenth century had relied on an extensive pharmacopoeia of herbal abortifacients and contraceptives to regulate fertility. In Eve’s Herbs, Riddle explores a new question: If women once had access to effective means of birth control, why was this knowledge lost to them in modern times?

Beginning with the testimony of a young woman brought before the Inquisition in France in 1320, Riddle asks what women knew about regulating fertility with herbs and shows how the new intellectual, religious, and legal climate of the early modern period tended to cast suspicion on women who employed “secret knowledge” to terminate or prevent pregnancy. Knowledge of the menstrual-regulating qualities of rue, pennyroyal, and other herbs was widespread through succeeding centuries among herbalists, apothecaries, doctors, and laywomen themselves, even as theologians and legal scholars began advancing the idea that the fetus was fully human from the moment of conception.

Drawing on previously unavailable material, Riddle reaches a startling conclusion: while it did not persist in a form that was available to most women, ancient knowledge about herbs was not lost in modern times but survived in coded form. Persecuted as “witchcraft” in centuries past and prosecuted as a crime in our own time, the control of fertility by “Eve’s herbs” has been practiced by Western women since ancient times.
