mostly discredited in more recent studies. Its general ethical principles are also found in other works of the Corpus: the Physician mentions the obligation to keep the 'holy things' of medicine within the medical community (i.e. not to divulge secrets); it also mentions the special position of the doctor with regard to his patients, especially women and girls. However, several aspects of the oath contradict patterns of practice established elsewhere in the Corpus. Most notable is its ban on the use of the knife, even for small procedures such as lithotomy, even though other works in the Corpus provide guidance on performing surgical procedures. Providing poisonous drugs would certainly have been viewed as immoral by contemporary physicians if it resulted in murder. However, the absolute ban described in the oath also forbids euthanasia. Several accounts of ancient physicians willingly assisting suicides have survived. Multiple explanations for the prohibition of euthanasia in the oath have been proposed: it is possible that not all physicians swore the oath, or that the oath was seeking to prevent widely held concerns that physicians could be employed as political assassins. The interpreted AD 275 fragment of the oath contains a prohibition of abortion that is in contradiction to original Hippocratic text On the Nature of the Child, which contains a description of an abortion, without any implication that it was morally wrong, and descriptions of abortifacient medications are numerous in the ancient medical literature. The oath’s stance on abortion was unclear even in the ancient world where physicians debated whether the specification of pessaries was a ban on simply pessaries, or a blanket ban on all abortion methods. Scribonius Largus was adamant in AD 43 (the earliest surviving reference to the oath) that it precluded abortion. In the 1st or 2nd century AD work Gynaecology, Soranus of Ephesus wrote that one party of medical practitioners followed the Oath and banished all abortifacients, while the other party—to which he belonged—was willing to prescribe abortions, but only for the sake of the mother's health. William Henry Samuel Jones states that "abortion…though doctors are forbidden to cause it, was possibly not condemned in all cases". He believed that the oath prohibited abortions, though not under all circumstances. John M. Riddle argues that because Hippocrates specified pessaries, he only meant pessaries and therefore it was acceptable for a Hippocratic doctor to perform abortions using oral drugs, violent means, a
