[Writing in his 1564 Monas Hieroglyphica, Dee has a sudden anxiety he is sinning by giving away too many of God’s secrets. The Monas was Dee’s magnum opus, his alchemical meditation on the cosmos. He needn’t have worried: apparently the Monas is incomplete without an accompanying explanation or because too many years have passed, and we’ve lost the context of the 15th century. ]
…Thus it is demonstrated that it must not be divided. All the parts of a line are lines. This is a point, and this confirms our hypothesis. Therefore, the point does not form part of our Binary and yet it forms part of the integral form of the Binary. It follows that we must take notice of all that is hidden within this hypostatic form and understand that there is nothing superfluous in the linear dimension of our Binary. But because we see that these dimensions are common to both lines, they are considered to receive a certain secret image from this Binary. By this we demonstrate here that the Quaternary is concealed within the Ternary. 0 God! pardon me if I have sinned against Thy Majesty in revealing such a great mystery in my writings which all may read, but I believe that only those who are truly worthy will understand.
[The Monas Hieroglyphica is also the symbol – an amalgamation of symbols – he designed which encompasses the cosmos:]
From Wikipedia on Rosicrucianism:
It is evident that the first Rosicrucian manifesto was influenced by the work of the respected hermetic philosopher Heinrich Khunrath, of Hamburg, author of the Amphitheatrum Sapientiae Aeternae (1609), who was in turn influenced by John Dee, author of the Monas Hieroglyphica (1564). The invitation to the royal wedding in the Chymical Wedding of Christian Rosenkreutz opens with Dee’s philosophical key, the Monas Hieroglyphica symbol. The writer also claimed the brotherhood possessed a book that resembled the works of Paracelsus.Pasted from <https://en.wikipedia.org/wiki/Rosicrucianism>
