De motv natvraliter accelerato tractatvs physico-mathematicvs : in qvo discvssis aliqvot recentiorum sententiis, vera accelerationis grauium ratio demonstratur.
A 1649 Latin physics treatise on natural accelerated motion by Jacques-Alexandre Le Tenneur, printed in Paris by Ludovicus Boullenger for a scholarly readership of natural philosophers and mathematicians. Its pictures are a pair of woodcut ornaments showing a crowned monogram flanked by palm fronds and a cherub, plus folding pages of geometric diagrams with ruled lines, lettered points and triangles that suggest a designer's use of schematic line work and vintage printer's ornament.
