Ten ways of seeing
- measured cast yellow-green
- upright 1.81 : 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
The binomial is Euphorbia clava: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. The Chinese name 飞头蕃 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 14.7% of the sheet, foliage 0.0%, the cast yellow-green with a second note of amber. 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 tall. No details are appended: a plate for looking, not for keying out. The plant covers only 16% of the sheet, centred above 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. There is evidence on the back too: the plate mark pressed into the paper, the slight relief of the pigment, lines worn shallow in a later printing. 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
一夜不眠孤客耳，主人窗外有芭蕉。
—— 唐·杜牧《雨》
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. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
The tropics have no four seasons, only wet and dry. 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 1781 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
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin'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. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1781.
