Ten ways of seeing
- measured cast amber
- slightly upright 1.28 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
Slightly taller than wide; the eye lands above centre. 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
Measured on this plate: flower colour covers 8.5% of the sheet, foliage 6.8%, the cast amber with a second note of yellow-green. No other plate shares exactly this measure. Tropical plants defy temperate habits: heavy, saturated flowers with strong scent, leathery or dissected leaves, stems that climb, swell, or reduce to spines.No colour group is recorded. A single plant, laid out with nothing hidden.
Composition
The sheet is slightly tall. No details are appended: a plate for looking, not for keying out. The plant covers only 18% of the sheet, centred near the centre; the emptiness is where the eye rests.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. 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
山城过雨百花尽，榕叶满庭莺乱啼。
—— 唐·柳宗元《柳州二月榕葉落盡偶題》
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
In China these plants carry no classical symbolism; their meaning is newness — new worlds, new species, new trade routes. They show natural history's expanding edge. In a flora it is a species first and a symbol second; the order is worth keeping.
Season and Place
flowering follows the first rains, so a month on the plate often means 'after the rain'. Central and South America, Southeast Asia, India, Ceylon. Eighteenth- and nineteenth-century artists either sailed with the ships or drew from living specimens under glass. The year 1719 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
“Dissertatio de generatione et metamorphosibus insectorum Surinamensium” carries only Maria Sibylla Merian'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
Carry three rules away: whole before detail; line before colour; picture before book. A flora exists to be consulted; look long enough and you forget to consult — someone in 1719 gave a whole day to a single flower.
