Novarvm observationvm physico-mathematicarvm
Novarvm observationvm physico-mathematicarvm is a 1647 astronomy and physics treatise by the French scholar Marin Mersenne, printed in Paris by Antoine Bertier for a learned readership of natural philosophers and mathematicians. Its pictures are letter-labelled geometric diagrams: circles with radiating lines and intersecting arcs, some showing planetary orbits and others construction geometry. A designer might take their clean, precise line work and the rhythm of labelled points and arcs as a model for technical diagrams.
