Costus arabicus (1719)
Ten ways of seeing
- measured cast amber
- upright 1.36 : 1
First Look
真山水之川谷，远望之以取其势，近看之以取其质。
—— 宋·郭熙《林泉高致·山水训》
Mountains and valleys: from afar take their momentum, up close take their texture — the two distances from which any picture is read.
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 where the green is deepest: the whole tonal order is measured from that patch.
Name and Thing
The binomial is Costus arabicus: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. The Chinese name 美洲宝塔姜 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 7.3% of the sheet, foliage 18.4%, the cast amber. 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. a moss green. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant takes about 29% of the sheet, centred near the centre — the easy measure most florists kept to.
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
海客谈瀛洲，烟涛微茫信难求。
—— 唐·李白《梦游天姥吟留别》
Seafarers talk of Yingzhou, lost in mist and waves, truly hard to find.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the green 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. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
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 1719 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The bud and the ripe fruit on one branch tell the season; the name in the title often tells the journey.
The Book and the Hand
“Dissertatio de generatione et metamorphosibus insectorum Surinamensium” carries only Maria Sibylla Merian's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Next time you stand before a flowering plant, give it three minutes: leaf arrangement, direction of the flower, the darkest patch. The flower of that year is dust, yet its image on paper has outlived every living cousin.
