The equipment of a Germanic warrior from the 2nd–4th century AD: Digital reconstructions as a research tool for the behaviour of archaeological costumes
Virtual reality opens new ways for reconstructing, preserving and exhibiting clothing and textiles. This applies particularly to those from an archaeological context, which can be incomplete, damaged or fragile. Despite the possibilities of computer technology, such as computer graphics (CG) and computer-aided design (CAD), its potential has only been superficially explored. This article showcases its possibilities by focussing upon the equipment of a Germanic warrior from the 2nd–4th century AD. His panoply consists of trousers, a tunic, shoes, a mail coat, an under-armour garment and a belt. CG and CAD tools, such as stress analysis and strain analysis, were applied to visualize and examine the behaviour of his equipment. The military clothing of the Germanic warrior proves very functional in terms of physics, materials science, anatomy and biomechanics. In other words, his clothing and armour result very suitable for warfare. This case study demonstrates that digital reconstructions can be more than scientific visualisation, but also a new and powerful research tool, generating new insights into archaeological artefacts
Testing archaeological mail armour in a virtual environment:3rd century BC to 10th century AD
This article presents a new method for examining mail through the use of digital reconstruction and computer simulation. The method allows the physical and mechanical properties of mail artefacts to be reconstructed, which otherwise remain hidden, by performing tests in a virtual environment. Ten archaeological finds, dating between 300 BC and 1000 AD, were parameterized and reconstructed. Testing procedures were developed to measure the properties of the mail fabrics. A physics engine was employed to simulate the behaviour of the specimens under the influence of external forces. Six important characteristics (i.e. stretch, stiffness, number of rings per unit area, mass per unit area, thickness, and covered area ratio) were calculated for each specimen and compared to each other to identify distinctive features. This was followed by a correlation analysis to understand how the rings’ geometrical parameters influence the properties of the mail fabric and how these properties are balanced. The method demonstrates that not all mail is alike and that certain characteristics were favoured during certain times. The first careful results point to Iron Age mail being heavy and stiff, while mail during the Principate became much lighter and more flexible. During Late Antiquity this was again reversed in favour of heavier mail. The subsequent medieval period up to the 10th century demonstrates a balance between these characteristics
