Ten ways of seeing
- broad 0.76 : 1
First Look
论画以形似，见与儿童邻。
—— 宋·苏轼《书鄢陵王主簿所画折枝》
To judge painting by likeness alone is the view of a child.
Broad and horizontal: the eye travels side to side. Find where it stops. 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 Convolvulus is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Garden annuals and low perennials: many small, brilliantly coloured flowers to a stem, with leaves palmately lobed, pinnate or entire — the mainstay of the Victorian bedding scheme.No colour group is recorded. Read the outline, then the colour layers, then the brush.
Composition
Broad and horizontal — the format for groups or a whole plant with its roots. 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
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
余既滋兰之九畹兮，又树蕙之百亩。
—— 战国·屈原《离骚》
I have planted nine acres of orchids and set out a hundred acres of sweet flag.
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the corolla becomes its resting point.
Symbolism
Bedding plants carry no imperial weight; they mean the everyday — window sill, border, festival, gift. Victorian floriography grew up among exactly these flowers. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
Late spring to early autumn, June through September. Gathered from everywhere by plant hunters and the glasshouse trade: pelargoniums from South Africa, campanulas from European mountains, lobelias from North America, fuchsias from Chile. The year 1754 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 natural history of Carolina, Florida, and the Bahama Islands” carries only Mark Catesby'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.
