The Theoretical Brothers, or the Second Stage of the Rosicrucians

A printed emblem appears on a pasted rectangular white card. The emblem features a golden oval frame with an inner blue field. At the top of the oval, golden rays shine downward from a sun like arc. In the center, a white pelican is depicted in her piety, piercing her breast to feed three chicks in a nest. This image represents the alchemical process and self sacrifice. Below the nest is a square device divided into four quadrants, each containing a red rose. Surrounding the oval in a circular arrangement is the text: Hermetic Philosophy original Latin: "PHILOSOPHIA • HERMETICA".
