Gunner's Level and Alidade
notes: label: Description
content: Gunner’s levels came into use in in the sixteenth century, along with the increased use of heavy artillery that could be adjusted for elevation. Intricate and delicate examples were presumably used for display rather than service on the battlefield. The “Johan Wolf Gelb me fecit Ulm” inscription on this complex instrument is that of Johann Wolfgang Gelb, a locksmith and small clock maker born in Ulm in 1599.
