An Essay on the Chemical History and Medical Treatment of Calculous Disorders Pl.6 (1819)
Ten ways of seeing
- upright 1.64 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
The sheet is vertical: the eye climbs and settles in the upper half. Let the plant stand before you look for detail. 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
No reliable binomial survives, so the printed title must serve. Neither name nor binomial survives: the printed title must do.
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
Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. No details are appended: a plate for looking, not for keying out. Cover the margins with your thumb and the plate suffocates; uncover them and the flower breathes again.
Line and Colour
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. 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
朝饮木兰之坠露兮，夕餐秋菊之落英。
—— 战国·屈原《离骚》
At dawn I drink the dew fallen from magnolia; at dusk I dine on the fallen petals of autumn chrysanthemum.
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
the rest of the year it is only a mass of leaves. 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 1819 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. Read the locality and the flowering season both with a discount: one is hearsay, the other a ten-day peak.
The Book and the Hand
“An Essay on the Chemical History and Medical Treatment of Calculous Disorders” carries only Alexander Marcet's name. A plate is collective work: drawer, engraver and colourist were different hands, and the unnamed ones decided how good it looks.
What to Take Away
Next time you stand before a flowering plant, give it three minutes: leaf arrangement, direction of the flower, the darkest patch. A flora exists to be consulted; look long enough and you forget to consult — someone in 1819 gave a whole day to a single flower.
