This paper reviews some of the visualizations employed to represent information during the Middle Ages. It discusses three kinds of visualizations: rotae, tables and trees, and considers their context and use.
ABSTRACT Displaying digital art in the late twentieth and early twenty-first centuries is already proving to be a challenge. Exhibiting this same art in the distant future will depend upon new thinking and practices developed today by artists, conservators, and curators. Established software engineering methods for dealing with aging systems can provide a new model for the conservation of digital art, and a foundation for the enhancement of art-historical scholarship. Artists with an interest in a more refined approach to the programming that underpins their work will also be interested in software engineering concepts.
