In this volume I have attempted to give especial and marked attention to the fate of Greek science in late antiquity. Elementary texts in the past have long ignored this aspect of Greek science. The importance of the course of Greek science in late antiquity is evident, for it was during this period that much of the Greek scientific corpus was put into the form in which it passed to the medieval Latin West. We are justified, then, in considering this volume as an introduction to medieval and early modern science—that science being considered as a transformation of Greek science.
