The above fresco was an inspiration for Renoir for the Grand Bathers.
Raphael Sanzio, The Triumph of Galatea, Pompei Fresco was an early 16th-century romantic inspiration
for Pierre-Auguste Renoir Grand Bathers also in the water and land.

Renoir studied the above sculpture, The Bathing Nymphs, bas-relief, executed after models designed by
Francois Girardon (1628-1715) 1668-70 (lead, formerly gilded), to create an inspired post-classical-like
tight futuristic, detailed sculptural pastel study of the two front models in his own new interpretation of
infinite light, envisioning a new style in 1883. Water below the bas-relief influenced The Grand Bathers,
where the figures are heavenly, and the water below is earthly.
Note the grain in the paper below. Artists of the time were working on cotton, rag, or woven paper.

What was Gillotage Paper?
In the mid-to-late 19th century, before newspapers could easily print photographs, they needed a way to turn
an artist's drawing into a metal "relief" plate for a printing press.
The Texture: Gillot paper (also called papier procédé) was a thick, specially coated paper with a mechanical
grain (usually tiny dots, lines, or a cross-hatch pattern) embossed into the surface.
The Effect: When Renoir drew on it with a greasy lithographic crayon, the crayon only hit the "peaks" of the
embossed grain. This automatically broke his drawing into a pattern of tiny dots—essentially a manual version
of a "halftone" used in modern printing.
The Process: The drawing would then be transferred onto a zinc plate. The dots created by the paper's grain
acted as a resist, allowing the acid to eat away the rest of the plate, leaving a printable relief of the
drawing.
Why is it so rare (The "Single Roll" Story)? The story you read in Ambroise Vollard’s Renoir: An Intimate
Record and John Rewald’s Renoir Drawings is famous among art historians but obscure to the general
public.
The "Perfect" Grain: Renoir discovered a specific batch of this paper that had a grain so fine and delicate it
perfectly mimicked the softness of human skin and the atmospheric light of his "Bathers" period.
Industrial Obsolescence: As Charles Gillot perfected photogravure (using photography to make plates), the need
for these expensive, manually-grained papers vanished. The factory stopped producing the specific roll Renoir
loved because there was no longer a commercial market for it in the magazine industry. Why is this crucial for
the Renoir pastel case?
If your pastel is on this specific Gillot paper, it is a massive piece of evidence.
The "Fingerprint": Because that paper was produced only for a short window of time (roughly the 1870s–1880s)
and from a specific industrial source, the embossed pattern on the paper serves as a fingerprint. Renoir's
Hoard: Renoir reportedly bought as much as he could find, but as Vollard notes, once that "single roll" (or
specific production run) was gone, it could never be replicated. The chemicals and the physical metal rollers
used to emboss that specific grain were destroyed or replaced.
The Match: If the grain pattern on your pastel matches the grain pattern on the Renoir studies in the Musée
d'Orsay or the Metropolitan Museum of Art, it is physically impossible for it to be a fake.

The creases in the above photo are characteristic of the paper Renoir used in all his studies for the Great
Bathers—photograph and discovery by Gregory Kitchen. The photograph is of the Pastel Study under glass
framing, as discovered in 1993. Background figure left arm and foreground figure right foot.

The creases in the background figure's right arm and the foreground figure's right arm and right knee in the
photo above are characteristic of the paper Renoir used in all his studies between 1883 and 1888, including
the Great Bathers. The paper was full of these manufacturing defects, which Renoir loved to work into his
compositions. This is a section of a Pastel Study under glass framing, as discovered in 1993. Note the
pastel dust striping on the inside of the glass from vibration of the antique cardboard backing during 30
years of storage. Photograph, and discovery of the work, by Gregory James Kitchen, New York.

Above is cropped detail of Renoir's sanguine drawing study under glass for The Grand Bathers, with
identical creases and paper grain to the paper of The Pastel Study for the Grand Bathers. Photo by Fogg

The above picture of the framed figurative Pastel Study for the Grand Bathers emphasizes the condition
of the inside of the framing glass when the Pastel Study was purchased at the antique show on 18th Street,
New York City, in 1993. The cardboard backing of the framing vibrated against the paper of the pastel,
causing pastel dust striping by making the pastel painting touch the glass in storage over the period from
1965 to 1993. This is common when pastel has not been correctly stored. We kept the Pastel Study in the
frame with the glass as purchased until the McCrone Associates did the pigment testing in September
1999. Photographed with racking light, by Greg Kitchen, New York, 1999. The layer of pastel is so thin
that Renoir added blue watercolor to the skin.

The above photo is the reverse side of the Grand Bathers Pastel Study paper, a felt, not a screen grain,
as the front side. Also visible here is the residue of antique cardboard backing, which remained stuck
after
the cardboard was scraped off when the Grand Bathers Pastel Study was removed from the frame to be
restored in the 1930s.


The above photo of paper fibers of the pastel study under a microscope is consistent with all the paper of
Renoir’s studies on guilattoge paper.

Two examples below of Renoir using optics reproduced from Barbara White’s book, Renoir His Life, Art
and Letters. The compositions of the foreground are so much alike, as they were traced from the same
painting. The dimensions of the works are different, as one is much smaller, but the proportions of the
figures to the canvas are the same.

Above is one of the letters of support from Monsieur Francois Daulte, the late Renoir expert, stating
“Pastel”

The letter above is from Monsieur Guy-Patrice Dauberville, the present Pastel Expert, who stated he
wanted to see the pastel study.

The above label was on the back of the framing, is dated as from the 1930’s by by the print style of the
type used, and the telephone number.

Above is Pierre-Auguste Renoir’s signature on the front lower left of the Pastel Study.

Aline was the love of Renoir's life and was the perfect model for his painting. Posing long
hours for him. Renoir thought Aline was the perfect model for his paintings.
