Twelve Gallo-Roman wooden tablets incised with texts from Tongeren were subjected to the method of Multi-Light Reflectance imaging to record and enhance their readability. Each of the sides of the fragments was recorded with a White Light Microdome, a method that casts lights on their surfaces from 228 different angles, ranging from perpendicular to oblique, and raking over 360°. The processed dataset allows an interactive inspection of the incised features by manipulating the virtual light sources and activating specific appropriate visual styles in an open-sourced, browserbased, viewer. Apart from the incised text marks, the method likewise serves to develop a dynamic record of the wooden tablets themselves (medium) and their state of preservation at the moment of the digitisation. The final results are made available by means of a IIIF implementation bearing a unique digital ID guaranteeing their long-term preservation.
