Technical Observations: The patina is dark green with light gray accretions. Metal shows through where the patina is worn away. This is the right half of the lock and is intact; the left half and the locking mechanism are lost. There are many dents and areas worn from use. Some scrape marks on the surface appear more recent and are probably the result of a crude cleaning procedure.

This half was probably lost-wax cast, but sand casting is also possible. The two halves of the lock would have been separately cast, joined together, and then finished as a unit. Lead residue covers the join surface. Relief features, such as the notches in the horns, were cut in the metal with an abrasive tool.

Descriptions

Published Catalogue Text: Ancient Mediterranean and Near Eastern Bronzes at the Harvard Art Museums
This ibex-shaped figurine functioned as a lock. The animal has a distinctive rounded horn, articulated with a striated pattern to represent a spiral. It wears a harness at its shoulders. The lock was originally composed of two concave pieces joined together with pins, but the second, matching plaque is now lost. A locking mechanism was positioned in the interior. The separately cast bolt, also lost, slid horizontally into the lock; one prong entered the tail of the animal, the other entered a small groove between the horn and the head. To close the lock, the bolt was inserted through one end of the animal’s body and secured at the other. It is unclear whether the lock was released by a slide key inserted into the tail or chest of the animal or a turnkey inserted into the center of the lost plaque (1).

Locks of this design and style continued to be made in modern times (2). While the Harvard piece may be of medieval origin, it is equally possible that it was produced more recently.

NOTES:

Vikan and J. Nesbitt, Security in Byzantium: Locking, Sealing and Weighing (Washington, DC, 1980) 6, fig. 10.
