Wayne Hill found a reference to this 17th century artillery manual by one Casmir Siemienowicz, General of Polish-Lithuanian Commonwealth Crown Artillery. He also posted Cas' bio:
Kazimierz Siemienowicz, born near Raseiniai in Samogitia, was a Polish-Lithuanian commander in the Polish Royal Artillery. He was fascinated by artillery from childhood and studied to increase his knowledge in this area. He became an expert in the fields of artillery and rocketry. His Artis Magnae Artilleriae pars prima which was first printed in Amsterdam in 1650 became the standard book on firework displays, military and recreational pyrotechnics and rocketry for well over a century. In Artis Magnae Artilleriae pars prima, he published designs for multistage rockets, batteries of rockets, and delta wing stabilizers.
