Caterpillar of Metopsilus Tersa, Sphinx Chionanthi, Sphinx Gaurae (1833)
Ten ways of seeing
- upright 1.67 : 1
First Look
六法者何？一、气韵生动是也；二、骨法用笔是也；三、应物象形是也；四、随类赋彩是也；五、经营位置是也；六、传移模写是也。
—— 南齐·谢赫《古画品录》
The six laws: spirit resonance alive; bone-method in the brush; matching form; colour by kind; planning the placing; copying the masters.
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
Only the genus Sphinx is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
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. Read the outline, then the colour layers, then the brush.
Composition
Tall and narrow, the bird perched mid-branch with generous margins above and below. 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
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. 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
春风尔来为阿谁，胡蝶忽然满芳草。
—— 唐·李白《琴曲歌辞 山人劝酒》
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 1833 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
“The naturalist's library” carries only James Duncan'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
Next time you watch a bird: posture first, then where the plumage is deepest, and only then the field guide. The flower of that year is dust, yet its image on paper has outlived every living cousin.
