Germany / c. 1460–70
Crossbow
The Cleveland Museum of Art catalogs Crossbow as arms and armor (Germany · c. 1460–70).
In every army in Europe crossbowmen were considered an elite corps, and as such occupied the central position in battle formations.
A CLOSER LOOK
The museum identifies this arms and armor as wood (walnut?) inlaid with bone; horn; iron and steel; composite bow (horn and parchment).
The museum's collection notes: The cranequin, or winding device sitting on top of the crossbow, made it easier to span for reloading. With a full quiver, a container for bolts and arrows, a hunter could bring home plenty of meat.
