Ten ways of seeing
- measured cast yellow-green
- upright 1.50 : 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 where the green is deepest: the whole tonal order is measured from that patch.
Name and Thing
The binomial is Oncidium cavendishianum: 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
Measured on this plate: flower colour covers 8.3% of the sheet, foliage 12.8%, the cast yellow-green with a second note of amber. No other plate shares exactly this measure. Orchids carry pseudobulbs or fleshy roots; six tepals, one modified into a lip that serves as a landing stage, and a column uniting stamens and pistil — a structure unique to the family. a moss green. Read the outline, then the colour layers, then the brush.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant covers only 22% of the sheet, centred near the centre; the emptiness is where the eye rests.
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
我当二十不得意，一心愁谢如枯兰。
—— 唐·李贺《开愁歌》
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the green the corolla becomes its resting point.
Symbolism
In China the orchid is the gentleman who blooms unseen; in Victorian Europe it was luxury and obsession, a single new species worth a fortune. In a flora it is a species first and a symbol second; the order is worth keeping.
Season and Place
Varies by genus: temperate terrestrials flower in spring and summer, tropical epiphytes almost year-round. Worldwide, richest on tropical mountains. Chinese cymbidiums come from the hills of the south. The year 1837 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
“The Orchidaceae of Mexico and Guatemala” carries only James Bateman, Sarah Ann Drake's name. The image is public domain; the hand-colouring is still one person's hand.
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. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1837.
