Arbor Raritatis
The Tree as the central motif. From Monas Hieroglyphica.
What is happening
Symbolica, 2026 Dee's Latin, put into English here: The Tree of Rarity, and above it, Mysteries, described in this way from our Cosmopolitical Theories. The trunk is lettered Infantia, Pueritia, Adolescentia and Optio, the ages of a life up to the age of choice, where it forks into Terra and Aqua, earth and water, with the Greek words for the spiritual tyrant at the top. The figure is in the letter to the Emperor, before the theorems begin. Read again at the size of the archive's image: the trunk is lettered Infancy, Boyhood, Adolescence, Choice; at the fork Earth and Water; up the earth branch Abyss, Fraud, Care, Force, with numbers in the thousands and millions beside them; up the water branch the Philosopher, the Wise Man, the Adept, with Air and Fire beside the last two and the numbers thinning as they climb; and along the top, in Greek, the spiritual tyrant.

The picture
A tree drawn as a forked line and lettered, its trunk the ages of a life from infancy to choice, its two branches earth and water, the numbers of the rare set along them. 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.
‘Arbor Raritatis’, the tree of rarity. It stands in Dee's letter to the Emperor Maximilian before the theorems begin, headed ‘Mysteria: ex nostris hoc modo descripta Cosmopoliticis Theoriis’, mysteries described in this way from our cosmopolitical theories, and it is a tree only in the sense that it forks.
The trunk is a life, lettered from the root up ‘Infantia. Pueritia. Adolescentia. Optio.’: infancy, boyhood, adolescence, and then choice, at the fork. The two branches are the choice. ‘Terra. Aqua.’ stand at their roots, earth to the left and water to the right. Up the branch of earth climb ‘Abyssus. Fraus. Sollicitudo. Vis.’, abyss, fraud, care and force, with numbers beside them that run to a thousand million: this is where almost everyone goes. Up the branch of water climb ‘Philosophos. Sophos. Adeptivus.’, the philosopher, the wise man, the adept, in Greek and Latin, with air and then fire lettered beside the last two and the numbers dwindling as they rise. Along the top of the whole figure runs the Greek ‘Tyrannos pneumatikos’, the spiritual tyrant, over both branches.
The tree is rare because its good side is nearly bare. Dee counts the adepts in single figures and the deceived in millions, and draws the count as a plant, which is the one form that makes the two branches equal in length whatever their numbers. It is the only figure in the Monas that is about people rather than the sign, and it is placed before the sign is explained, as a warning about who will read the rest.
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.

A body drawn as growth. Note which way it grows and what is at the root rather than at the top.
In plain words A tree drawn as a diagram: a straight trunk that is a life, infancy at the root and choice at the fork, and two branches that are what the choice is between. Up the branch of earth go abyss, fraud, care and force, with numbers in the millions; up the branch of water go the philosopher, the wise man and the adept, with the numbers shrinking to a few. Dee calls it the tree of rarity because the good branch is the empty one.
