Turner’s Principle (1838)
Ten ways of seeing
- broad 0.58 : 1
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.
Broad and horizontal: the eye travels side to side. Find where it stops. 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
Broad and horizontal — the format for groups or a whole plant with its roots. No details are appended: a plate for looking, not for keying out. Old plates set the plant slightly off centre, with unequal margins — that small imbalance is what keeps it alive.
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
Plates usually record flowering, the fortnight when a plant is most identifiable. 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 1838 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
“Colour, as a means of art” carries only Frank Howard's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Appreciation is not knowledge but habit — one more look each time. A flora exists to be consulted; look long enough and you forget to consult — someone in 1838 gave a whole day to a single flower.
