Ten ways of seeing
- measured cast amber
- slightly upright 1.27 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
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.
Name and Thing
Only the genus Iris is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Measured on this plate: flower colour covers 7.0% of the sheet, foliage 4.7%, the cast amber with a second note of yellow-green. No other plate shares exactly this measure. Irises carry rhizomes or bulbs, sword-shaped leaves in two ranks, and six tepals — three falls drooping, often bearded or speckled, three standards erect.No colour group is recorded. A single plant, laid out with nothing hidden.
Composition
The sheet is slightly tall. No details are appended: a plate for looking, not for keying out. The plant covers only 17% of the sheet, centred below 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
彼泽之陂，有蒲菡萏。有美一人，硕大且俨。
—— 《诗经·陈风·泽陂》
On the bank of that pool grow rushes and lotus. There is a beautiful one, tall and grave.
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 sweet flag hung at the door wards off evil at midsummer; in Europe the iris is the messenger, since Iris was the rainbow goddess who carried divine words. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
Season and Place
Late spring to early summer, peaking in April and May, before the summer rains. Temperate north. In China iris and sweet flag belong to the Dragon Boat festival. The year 1773 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. Read the locality and the flowering season both with a discount: one is hearsay, the other a ten-day peak.
The Book and the Hand
“One hundred and twenty copper-plates of English moths and butterflies” carries only Benjamin Wilkes'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. A flora exists to be consulted; look long enough and you forget to consult — someone in 1773 gave a whole day to a single flower.
