Giovanni Giacomo Pierantoni

Giovanni Giacomo Pierantoni, also known as Gio. Giacomo Pierantoni, was an Italian mathematician of the seventeenth century. The only work credited to him in the English Wikipedia article is the Diverse operationi d'aritmetica, a book of arithmetic operations in Italian printed at Bologna by Giacomo Monti in 1652. That article gives no dates of birth or death and no details of his career, so this entry records only his nationality, his period and his book, which place him among the Italian authors of practical arithmetic texts of his century.
