La Rhubarbe des Boutiques (1787)

Twelve ways of seeing

One plate, read twelve times over: its name, its colour, the burin and the brush, the shape of the sheet, the season, the soil it came from, the book it belongs to, its language of flowers, the poem it answers to, the lore behind it, how to look, and what remains.

1. 01

   The Name

   The plate is titled “La Rhubarbe des Boutiques”, numbered Plate 23. No reliable binomial survives on the plate, so it must be cited by its original title. Neither a Chinese name nor a reliable binomial survives: the plate can only be cited by its printed title, and left to speak for itself.

2. 02

   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 for this plate, but the palette still belongs to its season. Read the outline, then the colour layers, then the touch of the brush.

3. 03

   Line and Colour

   Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring. Line and colour were done by different hands, which is why the two sometimes disagree. Look closely at the line and the colour: an unbroken line means engraving, colour crossing the outline by half a millimetre means hand-colouring. Craft leaves franker evidence than inscriptions.

4. 04

   Composition

   Tall and narrow, the plant rising in one movement with generous margins above and below — the upright format of most floras. (about 1.70 : 1). No details are appended: this is a plate for looking, not for keying out.

5. 05

   Season

   Plates usually record flowering, the fortnight when a plant is most identifiable; the rest of the year it is only a mass of leaves. The year 1787 on the plate is the year of publication, not of flowering — the gathering came a year or two earlier.

6. 06

   Provenance

   Various: local hillside or a plant brought from overseas. The nineteenth-century botanic garden and glasshouse were their first address away from home. The volume was made in 1787, when most of this knowledge came from living plants under glass rather than from the wild.

7. 07

   The Book

   “Cours de botanique” was drawn by Pierre Philippe Alyon and published 1787. This plate is Plate 23. The image is in the public domain; the hand-colouring on the paper is still one person's hand, two centuries ago.

8. 08

   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. In a flora it is a species first and a symbol second; the order is worth keeping.

9. 09

   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.

    Classical Lore

    China had the Bencao Gangmu and the Illustrated Study of Plant Names and Realities; Europe moved from herbal woodcuts to chromolithography. Both trusted pictures to finish what words could not. Chinese flower books ranked plants by character; European floras described them by form and name. This plate belongs to the second tradition, yet bears reading by the first. A flora asks what it is; a flower book asks what it means. Read both or half-read the plate.

    How to Look

    Look at the edge: where the plant is cropped tells you how it was seen — as specimen, as garden plant, or as wild thing. If you look at one thing, look at how flower meets stem; that joint is the hardest to draw and the surest to identify.

    Afterword

    A flora exists to be consulted; look long enough and you forget to consult — someone in 1787 gave a whole day to a single flower.
