SN - La gnomonique universelle ou la Science de tracer les cadrans solaires sur toutes sortes de surfaces - 1701

Rare illustrated edition of this scholarly work from the early 18th century, which belongs to the tradition of treaties on gnomonics, a discipline that combines mathematics, astronomy, and geometry for the art of designing sundials.

Presented as a 'universal science,' it outlines the theoretical principles of shadow projection and practical methods for adapting sundials to all kinds of surfaces — horizontal, vertical, inclined, cylindrical, or mobile — taking into account latitudes and orientations.

This treatise demonstrates the importance of gnomonics in the scientific culture of the emerging Enlightenment, where the art of measuring time by the sun was both practical, symbolic, and aesthetic, and where mathematical rigor was linked to the art of ornament and architecture.
