The video shows a 3D digital reconstruction of mail fabric from Gammertingen (c. 570 AD, Fürstliche Hohenzollernsche Sammlung, Sigmaringen). The find was reconstructed as part of a research project on computer reconstruction of archaeological mail armour. The developed method allows the physical and mechanical properties of mail artefacts to be reconstructed, which otherwise remain hidden, by performing tests in a virtual environment. The rings were reconstructed by using a set of measurements and connected in a so-called 4-in-1 pattern. Testing procedures were developed to measure the properties of the mail fabric. A physics engine was employed to simulate the behaviour of the specimen 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 and compared to each other to identify distinctive features. The authors of the reconstruction are Martijn A. Wijnhoven (VU Unive
