In Chymicis versanti Natura, Ratio, Experientia & lectio, sint Dux, scipio, perspicilia & lampas

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

Michael Maier, 1618 “In Chymicis versanti Natura, Ratio, Experientia & lectio, sint Dux, scipio, perspicilia & lampas.”

Symbolica, 2026 Maier’s Latin, put into English here: In chemistry let nature, reason, experience and reading be your guide, staff, spectacles and lamp.

Michael Maier, 1618 “Dux Natura tibi, tuque arte pedissequus illi
Esto lubens, erras, ni comes ipsa viae est.
Det ratio scipionis opem, Experientia firmet
Lumina, quo possit cernere posta procul.
Lectio sit lampas tenebris dilucida, rerum
Verborumque strues providus ut caveas.”

Symbolica, 2026 Maier’s epigram, put into English here: Let Nature be your guide, and follow her willingly with your art, for you go astray unless she is your companion on the road. Let reason give you the help of a staff, let Experience strengthen your eyes so that you can see things placed far off. Let reading be a lamp bright in the dark, so that you may be careful of the heaps of things and of words.

Nature walking ahead with flowers in her hand and fruit in her skirt, the old man following her with spectacles, a staff and a lantern, under a crescent moon. 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.

‘In Chymicis versanti Natura, Ratio, Experientia & lectio, sint Dux, scipio, perspicilia & lampas’: for the man who works in chemistry, let nature, reason, experience and reading be his guide, his staff, his spectacles and his lamp. Merian drew the four as a night walk: a woman striding ahead with flowers in her hand and fruit gathered in her skirt, and an old man following her with a staff, spectacles on his nose and a lantern held out.

‘Dux Natura tibi, tuque arte pedissequus illi / Esto lubens’, let nature be your guide, and follow her willingly with your art, ‘erras, ni comes ipsa viae est’, for you go astray unless she is your companion on the road. She walks in front and does not look back.

‘Det ratio scipionis opem’, let reason give you the help of a staff; ‘Experientia firmet / Lumina’, let experience strengthen your eyes; and ‘Lectio sit lampas tenebris dilucida’, let reading be a lamp bright in the dark, ‘rerum / Verborumque strues providus ut caveas’, so that you may be careful of the heaps of things and of words. The lantern in the old man's hand is the book. The lantern has an entry of its own in this archive, and Maier's is the plainest statement of what it carries.

The moon over the scene makes it night, which the lamp requires. Four instruments for one walk, and the one in front, who carries nothing, is the only one who knows the way.

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.
