German researchers uncover unique Roman padlock offering glimpse into ancient trade

In its recent article, The Independent features that researchers in Germany have uncovered a rare 1,600-year-old Roman padlock, offering a glimpse into the intricate craftsmanship of the ancient world. 

The padlock, which measures just over a centimeter, was found in the northwestern region of Westphalia.

"The golden miniature box lock is completely unique in Europe," said archaeologist Michael Rind from the Westphalia-Lippe Regional Association.

Researchers discovered that the artifact was a miniature version of locks commonly used throughout Rome during the third and fourth centuries, suggesting trade between the empire and northern Germany during that period.

"I could hardly believe it when I held the find in my hand because such Roman locks are usually much larger and are made of iron or bronze parts," said metal detectorist Constantin Fried.

The lock’s remains only included its cylindrical part, but it likely had a key and a chain in ancient times.

"Someone had obviously poked around in the lock at the time, probably to break it open or remove a blockage," Mr. Fried said.

Initial restoration efforts revealed that the central cylinder was made of iron.

More advanced CT scans, using neutrons instead of conventional X-rays, uncovered that the lock's inner mechanism contained a spring, bolt, baseplate, guide rail, and a pin.

Researchers suggested that the padlock may have been used to secure items such as jewelry boxes or chests, much like modern-day padlocks.

However, they were uncertain about the reason behind the creation of such a detailed lock and what it was used to secure by its German owners.

To better understand its mechanism, researchers created a larger replica of the lock using brass and steel. According to LWL cultural director Barbara Rüschoff-Parzinger, the replica highlighted the “high level of craftsmanship” of Roman blacksmiths and metalworkers.

Researchers also determined that the Westphalia region had interactions with Rome during that period. "Was it a one-time occurrence, or have similar precious miniatures just not been discovered before? We will continue to explore these and other questions," Mr. Rind said.
