Abstract
Iulia Concordia is an important Roman settlement especially known for the production of weapons during the Roman Empire. Excavations of the area revealed the evidence of metal-working activities and a huge number of well preserved arrowheads (sagittae) were found. In order to investigate the conservation state of the finds and to shed light about the production processes used by Roman for the manufacturing of sagittae, a neutron tomography analysis was performed on NEUTRA beam line at the Paul Scherrer Institut in Switzerland. Here, we present results from our investigation conducted on 18 samples, disclosing, in a non-invasive way, the morphological characteristic related to the ancient Roman working techniques.

Hereafter, we reported cross sections taken from the 3D reconstruction of the investigated arrowheads, which were not shown in the main section of the paper. The data are arranged according to the three different categories of samples: triangular, flat and quadrangular.
Each sample is virtually cut along three orthogonal directions: the upper image is always referred to the axial section, whose position is defined by the horizontal red line crossing the normal and transversal views, placed side by side on the bottom. The normal and transversal slices are acquired at the centre of the axial one. At the top of each slice-group, the sample reference number is reported.
1.1 Triangular arrowheads
1.2 Flat arrowheads
See Fig. 9.
1.3 Quadrangular arrowheads
