Sol & ejus umbra perficiunt opus

Sol & ejus umbra perficiunt opus

The Heavens as the central motif, with the Sun and the Moon in a secondary part. From Atalanta Fugiens.

Michael Maier, 1618 “Sol & ejus umbra perficiunt opus.”

Symbolica, 2026 Maier’s Latin, put into English here: The Sun and its shadow complete the work.

Michael Maier, 1618 “SOL, fax clara poli, non corpora densa penetrat,
Hinc illi adversis partibus umbra manet:
Vilior hac rebus quamvis est omnibus, usu
Attamen Astronomis commoda multa tulit:
Plura Sophis sed dona dedit SOL, ejus & umbra,
Aurifera quoniam perficit artis opus.”

Symbolica, 2026 Maier’s epigram, put into English here: The SUN, bright torch of the sky, does not pass through dense bodies, and so a shadow stays on their far side. Cheap though this shadow is, cheaper than anything, it has brought many advantages to Astronomers in practice. But the SUN and his shadow have given more gifts to the Sages, since it completes the gold-bearing work of the art.

The great globe under the sun's rays with its own shadow thrown across the stars. 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.

‘Sol & ejus umbra perficiunt opus’: the Sun and its shadow complete the work. Merian drew a diagram rather than a scene: the globe of the earth, the sun's rays raking across it, and the cone of shadow it throws across a field of stars, with the moon caught at the edge.

‘SOL, fax clara poli, non corpora densa penetrat’, the sun, bright torch of the sky, does not pass through dense bodies, ‘Hinc illi adversis partibus umbra manet’, and so a shadow stays on their far side. The globe is the dense body, and the sun is present only as the lines that fall on it.

The shadow is the subject. ‘Vilior hac rebus quamvis est omnibus’, cheap though this shadow is, cheaper than anything, ‘Attamen Astronomis commoda multa tulit’, it has brought many advantages to astronomers in practice. ‘Plura Sophis sed dona dedit SOL, ejus & umbra’, but the sun and his shadow have given more gifts to the sages, ‘Aurifera quoniam perficit artis opus’, since it completes the gold-bearing work of the art. The alchemists' sun is gold and its shadow is whatever is not gold in the matter, and Maier's point is that the work needs both: the light and the dark it makes.

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.
