Paraphrase de l'astrolabe, : contenant les principes de geometrie. La sphere. L'astrolabe, ou, declaration des choses celestes. Le miroir du monde, ou, exposition des parties de la terre
Jacques Focard's French-language treatise on the astrolabe, geometry, the sphere and world geography, printed by Jean de Tournes at Lyon in 1546 with woodcuts credited to Bernard Salomon, aimed at readers learning to use the instrument. The plates run from ruled gazetteer tables listing towns with longitude and latitude in Asia, Europe and Aquitaine to line diagrams of squares rotated within squares and small numbered grids, useful as letterpress table rules, geometric line motifs and early modern data layout.
