Iris I. Iris Susiana (1772)
Ten ways of seeing
- upright 1.59 : 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.
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
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
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. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. No details are appended: a plate for looking, not for keying out. Blank paper is not unfinished work: it 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. 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
手把菖蒲对佳节，兴来呼酒劝同僚。
—— 宋·王十朋《五月四日與同僚南樓觀競渡因成小詩四首明日同行可元章登樓又成五首 其二》
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. in Europe Iris germanica gave the perfume trade its orris root. The year 1772 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
“Hortus nitidissimis omnem per annum superbiens floribus sive Amoenissimorum florum imagines 1” carries only Christoph Jakob Trew's name. From drawing to plate the sheet passed through several hands — the engraver aimed at accuracy, the colourist at speed, and between them lies each plate's unevenness.
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 1772 gave a whole day to a single flower.
