This page consists of a large, complex magical diagram known as a Sigillum Dei (Seal of God), common in medieval and Renaissance grimoires. It features concentric circles, an interwoven heptagram (seven-pointed star), and a central pentagram (five-pointed star), all inscribed with divine names and the names of the seven planetary archangels.
These names are written on the primary interwoven bands of the heptagram.
