Dr. Sulzer’s Short History of Insects, Pl. 21 (1776)
Ten ways of seeing
- slightly upright 1.24 : 1
First Look
竖划三寸，当千仞之高；横墨数尺，体百里之迥。
—— 南朝宋·宗炳《画山水序》
A vertical stroke of three inches stands for a cliff of a thousand fathoms; a few feet of ink holds a hundred li.
Slightly taller than wide; the eye lands on the bird's head, a little 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
No reliable binomial survives, so the printed title must serve. Neither name nor binomial survives: the printed title must do.
Form and Colour
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. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
Slightly taller than wide, the bird set a little above centre, the eye landing at head and bill. 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. Take a loupe to three places: petal edge, leaf vein, caption. An unbroken line means engraving; colour crossing the outline means a hand. 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. In a flora it is a species first and a symbol second; the order is worth keeping.
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 1776 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
“Dr. Sulzer’s Short History of Insects” carries only Johann Heinrich Sulzer'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. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1776.
