According to the Fama Fraternitatis, the Rosicrucians rediscovered the lost tomb of their founder, Christian Rosenkreuz, while renovating one of their buildings. One of the Rosicrucians accidentally discovered a secret door hidden behind a stone wall. The door bore the words: post 120 annos patebo (once 120 years have passed). Behind the door was an elaborate tomb that represented Rosicrucian cosmology.
The tomb was a heptagonal (seven-sided) vault that represented the seven classical planets. It also represented the seven liberal arts and sciences. Each of these seven walls was divided into a grid of ten squares that represented the Tree of Life. The number ten also represented the Pythagorean ideal of perfection and completeness.
Each wall was 8 feet tall and 5 feet wide — an area of 40 feet — a number that is associated with spiritual renewal. There were a total of 70 squares (7×10); conversely, the RR+AC Vault uses a matrix of 40 squares, with squares that represent the elements, planets, and signs of the zodiac. Each wall also contained a cache of occult supplies that could be used to reconstitute the fraternity in case of its dissolution.
In the center of the tomb was a circular altar engraved with the words: hoc universi compendium unius mihi sepulchrum feci. This phrase can be translated to mean: “I have made my tomb to be the one compendium of the universe.” The circular altar was also engraved with four figures that represented the four elements. It also represented the four angels that surround the Throne of God. It also represented the four chambers of the human heart that house the dormant spirit of Christ. It was also analogous with the Round Table of Arthurian legend.
The ceiling that illuminated the vault with light represented the Limitless Light of the Cabalists. The floor, inscribed with the names of inferior spirits, represented the darkness of the underworld that Christ visited while he was dead. It is between these polarities of life and death that Christian Rosenkreuz remained in suspended animation.
The “Sleeping King” is a prominent archetype in many legends. In Christianity, John the Evangelist shall sleep in his grave until the coming of the Antichrist. In Arthurian legend, King Arthur was taken to Avalon to sleep until he was needed again.
The tomb of Christian Rosenkreuz was analogous with the tomb of Christ. While an earthquake opened the tomb of Christ, a construction project opened the tomb of Christian Rosenkreuz. It was a womb that was impregnated with an embryo that gestated for a certain amount of time — 120 years in this case. It was the sealed flask of the alchemist that is opened once the fermentation process is complete.
The tomb represented the spiritualization aspect of fermentation. Like the spiritualized body of Christ, the spiritualized body of Christian Rosenkreuz was imperishable — impervious to the entropic forces of decomposition. Like the slain bull in the subterranean temples of Mithras, the body of Christian Rosenkreuz represented the spiritualization of the lower physical nature into a higher spiritual ideal. The transfigured body of Christian Rosenkreuz represented the infamous philosopher’s stone that is said to be located in the interior of the earth.
The sarcophagus of Christian Rosenkreuz represented the lower physical nature of man. It was the physical body formed from the dust of the ground. It was analogous with the sarcophagus that carried Osiris down the Nile after he was imprisoned inside. It was also analogous with the Ark that carried Noah over the waters of the deluge. On the contrary, the preserved cadaver of Christian Rosenkreuz inside the sarcophagus represented the eternal soul that sleeps in the grave. It is the soul that awaits either reincarnation or judgment.
