well illustrated, and the text includes tables giving the
positions of the various markings. The large folding
plate also provides full-sized diagrams that show exactly
how the markings on the quadrant arm and tangent,
chord and sine scales are created (see the illustration of
the diagram for the tangent lines). The work has thirteen
chapters of which all but the final one cover the sector—
its description, construction and application. The last
chapter deals with military problems, primarily those
encountered in gunnery such as the determining of the
caliber of cannonballs and properly aiming at targets.

Juan de Mariana was a Spanish Jesuit historian. Born
in Talavera de la Reina, he is known to have worked in
Toledo. Several authors with similar names—Giovanni
Mariani, who was an Italian arithmetician of the midsixteenth
century, and Johann Marinoni, an astronomer
and mathematician from Austria in the early 1700s—are
often confused with Juan de Mariana.
This is a work on the weights and measures used in
Spain during the sixteenth century. Mariana compares
them with ancient Greek, Roman, Hebrew, Arabic and
other systems and provides tables relating the different
systems. The title page contains a large Jesuit insignia.

This set of tables is a ready reckoner for the conversion
of various northern Italian weights and measures. The
first edition was in 1535, and editions are known as late
as the end of the sixteenth century.
