A hand-drawn circular diagram, likely a Lullian wheel or a cryptographic volvelle, consisting of several concentric rings and twelve radial segments. The diagram is drawn in ink on parchment or paper. The center contains small concentric circles with a central point. The radial segments contain characters written in both black and red ink. The use of multiple colors often helped the reader distinguish between different categories or "wheels" of information in Llull's system.
The characters within the segments, starting from the top and proceeding clockwise, are:
The diagram is overlaid with modern watermarks reading "Biblioteca Apostolica Vaticana" and "ALL RIGHTS RESERVED." Faint ink stains are visible in the center of the wheel.
