"Behold the Monas, the sacred symbol, wherein the mysteries of the heavens and the earth are conjoined in a single point of light! This hieroglyph, born of the divine intellect, doth proclaim the unity of all things: the Sun and Moon, the fire and water, the spirit and the flesh. For as the Creator hath set forth the firmament in measure and number, so too doth this sign reveal the proportion of the eternal to the temporal. Let the wise man contemplate its form, for in its lines and curves are hidden the secrets of the philosophers’ stone, the harmony of the spheres, and the ascent of the soul to the throne of the Most High. I, John Dee, have labored in the shadow of this truth, that the mind of man might pierce the veil and touch the infinite." — John Dee- Monas Hieroglyphica, The Unity of Creation
“We finish the brief hieroglyphic consideration of our Monad, which we would sum up in one only hieroglyphic context: The Sun and the Moon of this Monad desire that the Elements in which the tenth proportion will flower, shall be separated, and this is done by the application of Fire.” - John Dee
“This is John Dee's enigmatic treatise on symbolic language. Although published in 1564 at age 37, he considered it valuable throughout his life. The Monas is a highly esoteric work. In it he claims himself in possession of the most secret mysteries. He wrote it in twelve days while apparently in a peak (mystical) state: “[I am] the pen merely of [God] Whose Spirit, quickly writing these things through me, I wish and I hope to be.” He claims it will revolutionize astronomy, alchemy, mathematics, linguistics, mechanics, music, optics, magic, and adeptship.” - Esoteric Archives

Dee claimed was divinely revealed to him over a twelve day period
Aa series of twenty-four theorems interpreting his Monad glyph.
Dee dedicated the work to the then Holy Roman Emperor, Maximilian II, in an effort to gain his patronage, promising that the most secret mysteries concealed therein would revolutionise astronomy, alchemy, mathematics, linguistics, mechanics, music, optics, magic, and adeptship.
Dee wrote a commentary on it which serves as a primer of its mysteries. However, the obscurity of the commentary is such that it is believed that Dee used it as a sort of textbook for a more detailed explanation of the Hieroglyph which he would give in person. In the absence of any remaining detail of this explanation the full significance of the glyph may never be known.
Dee’s final remark of the text:
Vulgaris, Hîc, Oculus CALIGABIT, DIFFIDETQVE plurimum. “Here the vulgar eye will see nothing but Obscurity and will despair considerably.”
