3D reconstruction of the lipsanotheca of Santa María de Lillet. It is a unique lipsanotheca or reliquary, preserved in excellent condition and made of alabaster, with characteristics that make it an exceptional work since the rest of the lipsanothecs that have been preserved, at least in the Catalan area, in this material are shaped like a sepulchral casket. This lipsanotheca measures 14 cm. high and 10 cm. in diameter, it has a cylindrical shape, very slightly truncated conical and is made up of two parts: the container and the lid. Both pieces are decorated with geometric motifs and the lid is characterized by presenting two borders with inscriptions in careful Carolingian calligraphy that say: «+ SANCTA MARIA ET SANCTI MARTIALIS CONFESOR» and «+ VIDALUS PRESBYTER QUI ME FECIT IN HONORE«. The lid also has a rounded knob at the top as a handle in which a carved cross is inscribed.
