How and by what means was the world wiewed in the 11th-12th centuries?
The aim of this presentation will be threefold. On the one hand, to describe the ways in which the scholars of the 11th and 12th centuries represented the world, conceived the place of the Earth in the cosmos and the usefulness of a knowledge of geographical space, by underlining the problems of a scientific nature that arise from this. On the other hand, it should be remembered that geographical knowledge is often associated with other knowledge, most often in relation to astronomy and time (comput), in order to reflect the cosmic order. Finally, it will be necessary to measure the part played by the renewals brought about in the 12th century.
To do this, I will rely mainly on cartographical examples (diagrams and maps), focusing in particular on the Liber Floridus by Lambert de Saint-Omer.
