Hippocrates remains a figure shrouded in mystery. We have next to no indubitable facts about his life. Although a large number of texts attributed to Hippocrates have come down to us, we cannot be certain that any one of them was written by the historical Hippocrates. One of the most eminent historians of medicine, Philip J. van der Eijk, has recently argued that we should abandon the moniker 'Hippocratic'and simply talk about early Greek medicine, as the so-called Hippocratic Corpus is so diverse and contains writings from the fifth century BC to the first and second century AD. Not everybody, of course, would agree with this view, yet it shows that Hippocrates remains a hot topic of debate, which attracts an ever growing amount of scholarship.Hippocratic studies have grown enormously since the late nineteenth century. In the early twentieth century, there was a clear focus on editing texts according to the latest philological methods. The great editorial project Corpus Medicorum Graecorum began in 1904 with the publication of a manuscript catalogue by Hermann Diels .One of the questions that scholars hotly debated since antiquity is the so-called Hippocratic Question: what texts in the Hippocratic Corpus were written by the historical Hippocrates?
