Theoria Lunae, Eius Motum Per Eccentricum Et Epicyclum Demonstrans (1660)
Ten ways of seeing
- square 0.85 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
Nearly square, plant and detail each holding a corner. Then step in close: watch where colour meets line, and whether the line ever breaks. Third, find the darkest small patch: the whole tonal order is measured from there.
Name and Thing
The binomial is Theoria lunae: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
A botanical plate: one plant lifted from field or glasshouse and set at the centre of the sheet, root, stem, leaf, flower and fruit in turn, made legible, citable, transmissible.No colour group is recorded. A single plant, laid out with nothing hidden.
Composition
Nearly square, plant and details sharing the corners. No details are appended: a plate for looking, not for keying out. Blank paper is not unfinished work: it is where the eye rests.
Line and Colour
Before 1700 most botanical figures came from woodcut: thick, hard lines in relief, colour brushed on afterwards. Decide first whether it was printed or painted; only then discuss whether it is beautiful. If you mean to copy it: take its skeleton, its margins and the order of its colours; the burin's hatching is the language of copper — suggest it with pencil density, do not imitate it stroke for stroke.
Poetic Resonance
天地有大美而不言，四时有明法而不议。
—— 《庄子·知北游》
Heaven and earth have great beauty and do not speak.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the corolla becomes its resting point.
Symbolism
The symbolism of such a plate lies not in flower lore but in record: the belief that a plant deserves to be drawn accurately — the plainest ethic of the scientific age. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
Plates usually record flowering, the fortnight when a plant is most identifiable. Various: local hillside or a plant brought from overseas. The nineteenth-century botanic garden and glasshouse were their first address away from home. The year 1660 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. See this kind of plate in the flowering season if you can: once you have met the living flower, you stop reading only colour.
The Book and the Hand
“Harmonia macrocosmica” carries only Andreas Cellarius's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Appreciation is not knowledge but habit — one more look each time. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1660.
