Tithymalus Helioscopius – Titimalo Elioscopio – L’épurge. (Wart- weed) (1772-1793)
Ten ways of seeing
- upright 1.58 : 1
First Look
江馆清秋，晨起看竹，烟光日影露气，皆浮动于疏枝密叶之间。
—— 清·郑板桥《题画竹》
On an autumn morning at the river lodge I looked at the bamboo: mist, sunlight, dew, all drifting among the sparse and dense leaves.
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
The binomial is Tithymalus helioscopius: 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
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. 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. Blank paper is not unfinished work: it is where the eye rests.
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
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. Meanings change their tune: the same flower can say opposite things within a century.
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 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. 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
Appreciation is not knowledge but habit — one more look each time. The flower of that year is dust, yet its image on paper has outlived every living cousin.
