Ten ways of seeing
- measured cast red
- slightly upright 1.28 : 1
First Look
夫象物必在于形似,形似须全其骨气。
—— 唐·张彦远《历代名画记》
Likeness is the threshold; bone-and-breath is the point.
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. The pose leans left: the upper half carries 8 points further left than the lower — a living thing, not a diagram.
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 7.1% of the sheet, foliage 0.0%, the cast red with a second note of amber. No other plate shares exactly this measure. 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. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is slightly tall. No details are appended: a plate for looking, not for keying out. The plant covers only 11% of the sheet, centred above 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. Take a loupe to three places: petal edge, leaf vein, caption. An unbroken line means engraving; colour crossing the outline means a hand. 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
天地有大美而不言,四时有明法而不议。
—— 《庄子·知北游》
Heaven and earth have great beauty and do not speak.
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. In a flora it is a species first and a symbol second; the order is worth keeping.
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 1817 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
“Drawings of plants collected at Cape Town” carries only Clemenz Heinrich Wehdemann'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
Appreciation is not knowledge but habit — one more look each time. The flower of that year is dust, yet its image on paper has outlived every living cousin.
