Theorem XX: the monad divided into its members

Theorem XX: the monad divided into its members

The Sun and the Moon as the central motif. From Monas Hieroglyphica.

Symbolica, 2026 Dee's Latin, put into English here: Let us therefore distribute the Monad, placed in this new way, into its anatomical members B, D, C. The three lettered figures are the glyph taken to pieces, which is what the word anatomy means throughout the book.

Tap a motif on the picture, or a line below. Its note opens under the line, with the reading its author gave it.

  1. Primary motif

The monad taken apart into three figures lettered B, D and C, the sun and moon, the cross, and the sign of Aries. By eye

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.

‘Distribuamus igitur Monadem, (hoc novo modo locatam) in anatomica membra B. D. C.’: let us therefore distribute the monad, placed in this new way, into its anatomical members B, D, C. The figure is the glyph dissected and the parts laid out with letters, as an anatomist letters a plate.

At the left, one above the other, D and C: the sun's circle with its point, and beneath it the moon's crescent, lying on its back. Above them B, the crescent fixed to the top of the cross; at the right E, the circle on the cross, which by itself is the sign of Venus. Dee's word for all this is anatomy, and the figure is the dissection: the two lights that stand joined at the head of the monad are here taken apart and set down separately, so that the reader can see that the glyph was built and can be unbuilt.

The twentieth theorem goes on to do arithmetic with the pieces, and the figures that follow it in the book are numbers. The archive keeps the woodcut at the size of the page.

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.

Checked
the Internet Archive item metadata, 4 September 2026: Dee as author, Frankfurt, Wechel and Fischer, 1591, in the Getty Research Institute's alchemy collection. The figures are small woodcuts set in the text and are kept at the size of the scan; nothing is enlarged. The quotations were read off the page images. Not seen in the hand. The inscriptions were read again at the size of the archive's own image on 5 September 2026 and the marks measured on that image; Hebrew and Greek lettering is given in transliteration in the quotations.
