World map from the Christian Topography of Cosmas Indicopleustes, a 6th-c. merchant, traveler, and monk. Virtually alone among educated people of his time, Cosmas insisted that the earth was flat, overspread by the heavens like a box with a curved lid. Redrawn from a Vatican Library manuscript (Vat. Gr.699 fol. 40v) by Heinrich Winter. #cartography #mappamundi #manuscripts

An edge-notched card for a picture filing system, categorizing images by attributes / characteristics like "spiritual or mystical" and "protesting or in revolt" (but not "that have just broken the flower vase" or "that at a distance resemble flies"). From Stanley Rice's Book Design: Systematic Aspects (1978). #deadmedia #punchcards #indexing
