description: "Giovanni de Galliano Pieroni (1586–1654) was a military engineer specialized in erecting fortifications, architect, mathematician and astronomer who gained particular fame in his day as also as author of horoscopes. Early in his life, he became friendly with the astronomer, mathematician and physicist Galileo Galilei (1564-1642) – like Pieroni, Galileo also wrote on constructing fortifications, and the two shared interest in mathematics and astronomy. He was also a contemporary and friend of Johannes Kepler (1571-1630) while both spent time in Prague."
