Illustrated treatise on gunpowder and artillery; probably a copy of an early recension of Franz Helm's work Buch von den probierten Kü̈̈nsten that first appeared between 1527 and 1535. The title page includes language similar to that title and a date of 1562 (f. ii). The date is echoed in a note added at the end of the manuscript in another hand; this note also attributes the copying of the manuscript to Georg Ganser of Cham and suggests that it was translated from French into German (f. 265r).
