The lorica hamata is a type of mail armor used by primary legionary and secondary auxilia troops in ancient Rome.

Configuration

Lorica hamata A lorica hamata consists of alternating rows of closed washer-like rings and rows of riveted rings.

The metal used for the lorica hamata was chiefly bronze or iron.

A large lorica hamata could be comprised of up towards 30,000 rings.

The shoulders had flaps running from mid-back to the front of the torso. These flaps were connected by metal hooks (brass or iron) which in turn connected to studs riveted through the ends of the flaps.

Variants

Later versions of the lorica hamata often came with sleeves and protected the leg down to the knee.

When?

Lorica hamata was used by soldiers of the Roman Republic and the Roman Empire.

During the first century AD, the lorica segmentata began to gain ground, making the lorica hamata less common. By the 4th century however, the lorica hamata was once again considered standard-issue for Roman legionaries and was also used by auxiliaries. (For unknown reasons, the lorica segmentata fell out of favor in the early 4th century.)

Lorica plumata

The lorica plumata was essentially a lorica hamata, but the rings were adorned with small plumes (feather-like scales). The lorica plumata was only worn by military leaders, typically generals but sometimes also tribunes and above. We don’t know which name the Romans themselves used for this armor; the name lorica plumata was invented by modern scholars.

A lorica plumata wasn’t just difficult and time consuming to make, it also required much more maintenance than an ordinary lorica hamata.

We don’t know how useful a lorica plumata was in the field, but wearing something that looked as impressive as the lorica plumata might have been a way to scare the opponents and boost the confidence of the Roman soldiers.
