Note 747 — Chapter VII · (continued 2)

Cf. Lelewel, Epilogue, p. 229. “The progress of geographical science long continued to be slow,” says Hallam in his Literature of Europe. “If we compare the map of the world in 1651, by Nicolas Sanson, esteemed on all sides the best geographer of his age, with one by his son in 1692, the variances will not appear perhaps so considerable as one might have expected.... The Sanson family did not take pains enough to improve what their father had executed, though they might have had material help from the astronomical observations which were now continually made in different parts of the world.” The Sanson plates continued to be used in Johannes Luyt’s Introductio ad Geographiam, 1692, and in the Atlas nouveau par le Sr. Sanson et H. Jaillot, published in Paris about the same year.
