Melocactus Americanus trigonus flore albo – Cactus – Cereo Americano – figuier d’Inde (1772-1793)
Ten ways of seeing
- upright 1.58 : 1
First Look
夫象物必在于形似,形似须全其骨气。
—— 唐·张彦远《历代名画记》
Likeness is the threshold; bone-and-breath is the point.
The sheet is vertical: the eye climbs and settles in the upper half. Let the plant stand before you look for detail. 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 Cactus is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Tropical plants defy temperate habits: heavy, saturated flowers with strong scent, leathery or dissected leaves, stems that climb, swell, or reduce to spines.No colour group is recorded. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. 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. 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
馆娃宫中春日暮,荔枝木瓜花满树。
—— 唐·王建《舞曲歌辭 白紵歌二首 二》
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
In China these plants carry no classical symbolism; their meaning is newness — new worlds, new species, new trade routes. They show natural history's expanding edge. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
Season and Place
flowering follows the first rains, so a month on the plate often means 'after the rain'. Central and South America, Southeast Asia, India, Ceylon. Eighteenth- and nineteenth-century artists either sailed with the ships or drew from living specimens under glass. The year 1772 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. See this kind of plate in the flowering season if you can: once you have met the living flower, you stop reading only colour.
The Book and the Hand
“Hortus Romanus juxta systema Tournefortianum” carries only Giorgio Bonelli'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. A flora exists to be consulted; look long enough and you forget to consult — someone in 1772 gave a whole day to a single flower.
