Ten ways of seeing

First Look
论画以形似，见与儿童邻。
—— 宋·苏轼《书鄢陵王主簿所画折枝》
To judge painting by likeness alone is the view of a child.
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 Oncidium wentworthianum: 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 5.0% of the sheet, foliage 7.7%, 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.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 15% of the sheet, centred below 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. Craft leaves franker evidence than inscriptions. 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
兰风桂露洒幽翠，红来袅云咽深思。
—— 唐·李贺《洛妹真珠》
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 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. the orchids drawn for European portfolios came largely from the cloud forests of Central America and Southeast Asia. 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. 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 1837 gave a whole day to a single flower.
