Theorem XVIII: the monad within the egg
The Vessel as the central motif, with the Heavens, and the Sun and the Moon in a secondary part. From Monas Hieroglyphica.
What is happening
Symbolica, 2026 Dee's Latin, put into English here: From our twelfth and thirteenth Theorems it can be gathered that celestial Astronomy is as it were the Parent and Mistress of the inferior. And: we shall see exactly such an Anatomy of our Monad, showing itself to us thus always in the light and life of Nature. The egg is the vessel of the work with the heavens drawn inside it, and Dee reads his glyph along its axis.

The picture
An egg drawn in outline with the orbits of the planets inside it as dotted rings, the monad standing along its axis. By eye
The reading
The picture read whole, in the archive's words, from the sources quoted on the marks. Read on, and the picture follows: the motif under discussion keeps its colour.
‘Ex duodecimo et decimotertio Theorematibus nostris colligi potest, Caelestem Astronomiam, inferioris esse quasi Parentem et Magistram’: from our twelfth and thirteenth theorems it can be gathered that celestial astronomy is as it were the parent and mistress of the inferior. The figure that follows is an egg.
The egg is the vessel. Alchemists called their sealed flask the philosophical egg, because what happens in it is a hatching, and Dee draws the shell in a single outline, broad end down, standing on the page. Nothing marks it as glass; what marks it as a vessel is what is inside it, which is everything.
Inside the shell the heavens are drawn as dotted rings, the orbits of the planets nested one in another, with an inner oval round the sun. The signs stand on the egg's axis, Saturn and Jupiter in the outer rings, then the sun with Mars, Venus and Mercury about it, and the moon at the foot. ‘Talem ad amussim nostrae Monadis conspiciemus Anatomiam: in Naturae lumine vitaque sese sic nobis semper ostendentem’, we shall see exactly such an anatomy of our monad, showing itself to us thus always in the light and life of nature. The glyph's anatomy is the solar system, and the solar system fits in an egg.
The sun's circle is the centre of the inner oval and the moon's crescent is the foot of the whole egg, so the two lights that the fourteenth theorem says the mastery hangs from, ‘Ex Sole et Luna, totum hoc pendere Magisterium’, are here the centre of the yolk and the bottom of the shell. Between them, on the one line, the rest of the planets.
The figure is small and sits in the text; the archive holds it at the size of the page, with the line of the theorem visible beneath it.
Decoded: every motif is marked, and each mark carries the reading its author gave it, quoted from the text, or says that it is observed on the picture and not read. The reading above is the archive's own, made from those sources and no others.

Never the subject. What is inside it is.
In plain words The egg is the alchemists' name for the sealed vessel in which the work is done, and Dee draws it as an egg with the planets inside. The outline is the glass; the dotted rings are the orbits; the glyph runs down the axis from Saturn at the top to the moon at the foot. Celestial astronomy, the text says, is the parent and mistress of the inferior kind: the heavens are what happens inside the vessel.
John Dee, 1564 “Talem ad amussim nostrae Monadis conspiciemus Anatomiam: in Naturae lumine vitaque sese sic nobis semper ostendentem.”
Symbolica Dee's Latin, put into English here: we shall see exactly such an Anatomy of our Monad, showing itself to us thus always in the light and life of Nature.

A diagram of everything, drawn so that a person can be found inside it. Note where the human figure stands in the scheme.
In plain words Seven orbits drawn as dotted arcs inside the shell, the outer ones for the slow planets and an inner oval round the sun. It is the cosmos of the astronomers drawn into the alchemist's glass, which is the point of the theorem: the two astronomies, above and below, are one figure.
John Dee, 1564 “Ex duodecimo et decimotertio Theorematibus nostris colligi potest, Caelestem Astronomiam, inferioris esse quasi Parentem et Magistram.”

Gold, the perfected metal, and the illuminated intellect. The most overloaded symbol in the tradition.
In plain words The sun sits at the centre of the inner oval, the moon at the foot of the egg, and between them the signs of the other planets stand on the axis. Dee has already said the whole mastery hangs from these two; here they are the centre of the yolk and the bottom of the shell.
John Dee, 1564 “Ex Sole et Luna, totum hoc pendere Magisterium iam clare confirmatum est. Huius, etiam Termaximus ille Hermes, nos olim admonuit: eius Patrem Solem esse, asserens: Lunam autem, Matrem: nutriri vero scimus in Terra Lemnia.”
Symbolica Dee's Latin, put into English here: That this whole Mastery hangs from the Sun and the Moon is now clearly confirmed. Of this, thrice-greatest Hermes long ago warned us, asserting that its Father is the Sun and its Mother the Moon, and we know it is nursed in Lemnian earth.
