Ten ways of seeing
- measured cast yellow-green
- upright 1.77 : 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 on the bird. Take the posture before the plumage. 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
The binomial is Panax aculeatum: 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 泽西灯蛾 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 14.9% of the sheet, foliage 1.6%, the cast yellow-green. No other plate shares exactly this measure. Insect plates show the host plant and all four stages at once — egg, larva, pupa, adult — with wing venation, scales and antennal segments accounted for: the most technical branch of natural-history art.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 fills 44% of the sheet, centred near the centre — the herbarium way, drawn to be read whole.
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
穿花蛱蝶深深见，点水蜻蜓款款飞。
—— 唐·杜甫《曲江二首》
Butterflies thread the flowers, seen deep within; dragonflies touch the water and fly on, slow and deliberate.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the bird itself becomes its resting point.
Symbolism
In China the butterfly is dream and lovers, the cicada purity, the firefly a lamp for reading; in Europe the insect began as specimen before it became symbol. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
Set by life stage: butterflies in spring and summer, moths into autumn, beetles from May to July. Four stages on one sheet span a whole year. Merian's Metamorphosis Insectorum Surinamensium (1705) first showed insect stages with their host plants — the result of raising caterpillars in the Surinam forest with her daughters. The year 1781 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
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Carry three rules away: whole before detail; line before colour; picture before book. The flower of that year is dust, yet its image on paper has outlived every living cousin.
