Renaissance book on fireworks (which the author gets to after a long look at military artillery and proper ways to attack fortified cities) with lots of illustrations. Jean Appier (1596-1647) was a printer and engraver in Lorraine whose father had been an engineer (fortifications at Nancy among others). He added the Hanzelet to his name. Appier seems to have "borrowed" some material for his text and at least one device is probably more imaginary than plausible, but then you weren't planning to build any of this right?
