Diagram of the Winds (I) — "The T-O map of the inhabited world occupies the center of this wheel-shaped diagram. Twelve profile busts of the winds, their Latin names provided in encircling bands, are depicted in the diagram's wide outer ring; the narrower, unpainted ring just within it contains the winds' Greek names. The four major winds are associated with the four cardinal directions, with East located at the top of the wheel. The busts of the winds blow toward the Earth at the center of the diagram, and their breath, represented as green strokes, flows into the wheel's "spokes." Each spoke bears a brief characterization of the associated wind, and these are expressed mainly in the first-person, as if spoken by the wind itself. Thus, the spokes of this diagram function like speech bubbles in a modern cartoon."

Featured on PDR in the collection Cosmography Manuscript (12th Century)

This wonderful series of medieval cosmographic diagrams and schemas are sourced from a late 12th-century manuscript created in England. Coming to only nine folios, the manuscript is essentially a scientific textbook for monks, bringing together cosmographical knowledge from a range of early Christian writers such as Bede and Isodere, who themselves based their ideas on such classical sources as Pliny the Elder, though adapting them for their new Christian context. As for the intriguing diagrams themselves, The Walters Art Museum, which holds the manuscript and offers up excellent commentary on its contents, provides the following description:
