Magical diagrams were geometrical designs that depicted the secrets of creation and mysteries of deity, and they were said to be of importance to conjuration rituals. The most important diagrams were the Triangle, the Double Triangle (a six-pointed star known as the Seal of Solomon) and the Tetragram (a four-pointed star).
The Triangle was based on the idea of trinity as it's found in deity, creation and time. The Sign of Solomon symbolised the Macrocosm, and as it was created from two triangles its points totalled the number six. The Tetragram symbolised the four elements and was used to conjure the elementary spirits (sylphs of the air, gnomes of the earth, undines of the water and the fire salamanders). The Pentagram was viewed as the most powerful conjuration of any ritual, and it can represent evil or good. It was the sign of Christ when it had one point in the ascendant, and the sign of Satan when it had two points. Depending on its positioning, the Pentagram was used to evoke light or darkness.
