Prodromus in systema historicum testaceorum Pl.05 (1795)
Ten ways of seeing
- upright 1.64 : 1
First Look
凡画山水，意在笔先。
—— 唐·王维《山水论》
In painting, the intention precedes the brush.
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
No reliable binomial survives, so the printed title must serve. Neither name nor binomial survives: the printed title must do.
Form and Colour
A botanical plate: one plant lifted from field or glasshouse and set at the centre of the sheet, root, stem, leaf, flower and fruit in turn, made legible, citable, transmissible.No colour group is recorded. Read the outline, then the colour layers, then the brush.
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. Old plates set the plant slightly off centre, with unequal margins — that small imbalance is what keeps it alive.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Craft leaves franker evidence than inscriptions. 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
天地有大美而不言，四时有明法而不议。
—— 《庄子·知北游》
Heaven and earth have great beauty and do not speak.
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
The symbolism of such a plate lies not in flower lore but in record: the belief that a plant deserves to be drawn accurately — the plainest ethic of the scientific age. Flower language was added later; the flower knows nothing of it, and that innocence is part of its power.
Season and Place
Plates usually record flowering, the fortnight when a plant is most identifiable. Various: local hillside or a plant brought from overseas. The nineteenth-century botanic garden and glasshouse were their first address away from home. The year 1795 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
“Prodromus in systema historicum testaceorum” carries only Johann Nepomuk Spalowsky'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
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.
