'… this Cambridge Companion is an excellent introductory guide to many areas of science-style inquiry in classical antiquity, and it is especially useful for less well known domains like botany, music, mechanics, or meteorology. In another way its authors' diverse choices offer a snapshot of our current relationship to Greco-Roman philosophical and scientific activity: our questions about its history are open-ended, even if a high proportion of them are still about Aristotle.'
