This completes what I think one may state and defend on physical grounds concerning the foundations of Astrology and the coming year 1602. If those learned in matters of Physics think them worthy of consideration, and communicate to me their objections to them, for the sake of eliciting the truth, I shall, if God grants me the skill, reply to them in my prognostication for the following year. I urge all who make a serious study of philosophy to engage in (...) this contest. For it concerns our worship of God and the welfare of the human race. Meanwhile, I pray from the depths of my soul, through Christ our mediator, that for all and for each the coming year may be a very happy one. (shrink)

During the 17th century, important conventions for the visual representation of the Earth as a whole were established by writers of Theories of the Earth. This essay examines how the emergence of visual representations contributed to the establishment of a new print tradition of multicontextual discourse and critical debate. Four vignettes contrast varying uses of global depictions: the incidental global depictions and mathematical vision of Johannes Kepler; the cosmogonic sections and chemical vision of Robert Fludd; the geogonic sections and mechanical (...) vision of René Descartes; and the global views and classical vision of Thomas Burnet. The continuities of visual conventions and the contrasts of disciplinary perspectives and local contexts observed in these vignettes conforms well to the characterization of Theories of the Earth as an interdisciplinary print tradition.

The subject of meteorology was central to Girolamo Cardano’s thought. It held together his encyclopedism by tying the celestial realm to the sublunary world and human action. Meteorology, for Cardano, links abstract knowledge to the practical and operative. While many of his Aristotelian predecessors understood weather prediction as distinct from meteorology as a natural philosophical field, Cardano’s profound interest in conjectural arts and probabilistic reasoning led him to tie causal explanations to methods of forecasting future conditions of the air and (...) their effects on humans, especially regarding health and disease. While it might be expected that Cardano would have emphasized astrological tools for weather forecasting, instead he went in a different direction, namely, embracing the ancient tradition of weather signs and revising Aristotelian theories of winds. At the end of his career, which he mostly spent writing commentaries on Hippocratic writings, he integrated his understanding of weather signs with Hippocratic rules of prognosis, revising traditional understandings of the causes of winds.
