Pteromys Origonensis, Oregon Flying Squirrel. Natural size. (1845-1848)
Ten ways of seeing
- slightly upright 1.30 : 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.
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
The binomial is Pteromys origonensis: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. 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. A single plant, laid out with nothing hidden.
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. Cover the margins with your thumb and the plate suffocates; uncover them and the flower breathes again.
Line and Colour
The first half of the nineteenth century moved from copper to steel to lithography; stipple could render the softest transition. There is evidence on the back too: the plate mark pressed into the paper, the slight relief of the pigment, lines worn shallow in a later printing. 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
我梳白发添新恨，君扫青蛾减旧容。
—— 唐·白居易《逢旧》
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. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
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 1845 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. Read the locality and the flowering season both with a discount: one is hearsay, the other a ten-day peak.
The Book and the Hand
“The viviparous quadrupeds of North America” carries only John Woodhouse Audubon's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
If you keep one line, keep Guo Xi's: from afar its momentum, up close its texture. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1845.
