Anatomy of the Night-blowing Cereus; or Cactus Grandiflora of Linnaeus
Ten ways of seeing
- measured cast amber
- upright 1.34 : 1
First Look
江馆清秋，晨起看竹，烟光日影露气，皆浮动于疏枝密叶之间。
—— 清·郑板桥《题画竹》
On an autumn morning at the river lodge I looked at the bamboo: mist, sunlight, dew, all drifting among the sparse and dense leaves.
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 Cereus 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 7.8% of the sheet, foliage 0.5%, the cast amber with a second note of yellow-green. No other plate shares exactly this measure. Tropical plants defy temperate habits: heavy, saturated flowers with strong scent, leathery or dissected leaves, stems that climb, swell, or reduce to spines.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 14% of the sheet, centred near the 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. 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
日啖荔枝三百颗，不辞长作岭南人。
—— 宋·苏轼《食荔枝》
Three hundred lychees a day — I would not mind being a southerner all my life.
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 these plants carry no classical symbolism; their meaning is newness — new worlds, new species, new trade routes. They show natural history's expanding edge. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
The tropics have no four seasons, only wet and dry. Central and South America, Southeast Asia, India, Ceylon. Eighteenth- and nineteenth-century artists either sailed with the ships or drew from living specimens under glass. The year 1799 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
“New illustration of the sexual system of Carolus von Linnaeus” carries only Robert John Thornton, Carl von Linné'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. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1799.
