A high-resolution photogrammetric workflow based on focus stacking for the 3D modeling of small Aegean inscriptions

•A photogrammetric workflow based on focus-stacked macro images is applied for the first time to the 3D modeling of small Aegean inscriptions.•Close-range digital photogrammetry allows reconstructing the small signs of the inscriptions with a 3D density up to 30 microns.•The high degree of detail of the 3D models is compatible with the requirements of high standard paleographic analyses.•The use of 3D models highly improves the identification of signs of undeciphered Aegean inscriptions.
