Period: 3rd to 5th century CE (Late Antiquity).
Helmet Types: Galea (Weisenau), Niederbieber, Ridge Helmet and Spangenhelm.
Influences: Transition from Celtic designs to Persian (Sassanid) and Steppe forms.
Construction: Shift from single-piece forged helmets to helmets built from multiple plates.

Introduction
Throughout the long Roman history, the equipment of the legionary constantly evolved. The helmets from the 3rd to 5th centuries reflect an empire in transition. The armies were no longer uniform; equipment was produced in local workshops (fabricae) scattered across the Empire, which led to a fascinating mix of functional infantry helmets and richly decorated cavalry helmets.

Late Galea & the Niederbieber Helmet
Until the early 3rd century, the iconic Galea helmets (Weisenau-type) remained in use. The later Italic models (ca. 150 CE) received broader neck guards and cross-bracing on the crown to withstand the Dacian falx (sickle).
Around 180 CE, the Niederbieber helmet emerged. This "intermediate variant" offered even better protection for the face and ears. Although often classified as a cavalry helmet, this robust type was also worn by infantry during the Crisis of the 3rd century.
The Roman Ridge Helmet
At the end of the 3rd century, a radical break with the past occurred. The traditional helmets were replaced by the ridge helmet. This design, consisting of two or four plates connected by a central ridge, was inspired by Persian examples from the Sassanid Empire.
Intercisa-type
This type consisted of two halves. The helmets are recognizable by the "eye motifs" on the front and were often worn by the infantry. Some models, such as the Intercisa IV, were equipped with Christian symbols such as the Chi-Rho cross.
Berkasovo-type
Heavier helmets consisting of four plates. The famous Deurne helmet and the Berkasovo helmet are examples of this. These were often gilded and set with (glass) gemstones, intended for the cavalry elite or high officers.
Spangenhelms: The Power of Simplicity
The Spangenhelm was an efficient design built from metal strips (spangs) and plates. Although less sturdy than the ridge helmet, it was cheaper to produce and easier to repair in the field. This type was likely adopted from steppe peoples such as the Sarmatians and would remain popular well into the Middle Ages (12th century).
Influence on the Germanic World
The late Roman helmets had an enormous influence on neighboring peoples. The construction of the ridge helmet and spangenhelm formed the basis for the famous helmets of the Vendel Period and early Anglo-Saxon times, such as that of Sutton Hoo.
Frequently Asked Questions (FAQ)
Why did the design change from single-piece to multiple plates?
Single-piece forged helmets were time-consuming and required highly specialized craftsmen. Multi-plate helmets (such as ridge and spangenhelms) could be produced in large quantities in state workshops to quickly equip the growing armies.
What is the meaning of the "eyes" on the Intercisa helmet?
While this was partly decorative, it likely had an apotropaic function: it was intended to ward off the "evil eye" and protect the wearer on the battlefield.
Summary
The Niederbieber helmet formed the bridge between Classical Antiquity and Late Antiquity.
The Ridge Helmet introduced Eastern (Persian) influences to the Roman army.
The Spangenhelm was the most cost-effective solution and remained in use the longest.
The rich decorations on Berkasovo helmets showcase the status of the late Roman officer class.
