Roman Bronze Key Door-Lock Bolt

Roman Empire, c. 100–200 AD

A fascinating cast bronze door-lock bolt from ancient Rome, once part of the locking mechanism of a wooden door. The bolt would slide back and forth to secure or release the door, operated only by the correct key. The small perforations of varying shapes corresponded precisely to the wards on the matching key—an ingenious system preventing unauthorized access.

Early Roman keys demonstrated remarkable technical sophistication and aesthetic refinement, serving not only as functional tools but also as symbols of ownership and status for those with property to protect. Keys and locking mechanisms of this type were used for doors, chests, cupboards, and caskets, and occasionally crafted for ceremonial or votive purposes. This fine example embodies the ingenuity and craftsmanship characteristic of Roman domestic life during the Imperial period.

Good condition. Surface wear and abrasions commensurate with age, nicks and corrosion, with encrusted patina and rich earthen deposits throughout. Size approx. 6,2cm x 1,7cm x 0,7cm.

Provenance: Dutch private collection
