This article is from the book The Black Death by Horrox. This article specifically discusses how astrology could have caused the plague. Geoffrey de Meaux was an astrologer from French court wrote about the plague after its outbreak around 1345. The document is from the Bodleian Library in Oxford. This information can help us understand the experience of the Black Death because it gives us an insight as to how people were explaining the plague with the scientific reasoning that they had during this time. This article shows the audience explanations as to who got sick and why. The poor were more likely to get sick rather than the rich, we know this now because of how close the poor were living together. In de Meaux view of how the plague started it was because astrological reasons, more clearly it was because of Saturn and Mars lining up. De Meaux has a different view than other scientist who believed it was because of Jupiter, with this information people can give reasoning to things they cannot really explain.
