Jean de Beaulieu held the position of Ingénieur
géographe du Roi at La Rochelle. This is a multiplication
table, in several sheets, of all numbers up to 210 x 100.
A final sheet gives the decimal equivalent of fractions.
It is interesting that despite the fact the decimal point
had been in use since the early 1600s, this decimal table
still relies on the old form of notation with accents (5’
corresponds to 0.5; 25’’ to 0.25; 6666 4 to 0.6666, etc.)

Beausard, the editor of this work, was a professor of
medicine and mathematics at the University of Louvain.
The introduction describes elementary notions of
astronomy and the shadow scales on an astrolabe. This
is followed by seven different works on the annulus,
also known as the astronomical ring. The instruments
are mainly ring sundials, but some are also elementary
survey instruments. Detailed descriptions of the contents
of each work are given in the individual entries. Many
of these items were previously published in a work by
Dryander.
