Daryn Lehoux’s new book will forever change the way you think about garlic and magnets. What Did the Romans Know?: An Inquiry into Science and Worldmaking (University of Chicago Press, 2012) is a fascinating account of the co-production of facts and worlds, taking readers into the sciences of Rome from the first century BC to the second century AD. Masterfully blending approaches from the history and philosophy of science, Lehoux traces the significance of the “threefold cord” of nature, law, and the gods in making up the early Roman world.
