  Here is a French translation and commentary of 17 problems in Peter Roth's
Arithmetica Philosophica (1608). These problems are dealing with algebraic
equations of degree 5 or 6; moreover, among these problems, 14 are also dealing
with stereometry and polygonal numbers. These 14 problems are the only ones, in
the Arithmetica Philosophica, to combine these three distinct topics in a
single setting (algebra, stereometry, polygonal numbers).
