Up Close and Illuminated: Artist’s Methods and Materials in the Manton Collection By Leslie Paisley

From the Director

In July, my wife Mary and I had the pleasure of accompanying a group from the Sterling and Francine Clark Art Institute to London to view A Taste of Impressionism, an exhibition of Clark paintings at the Royal Academy of Arts. It was a spectacular installation and I, as a proud conservator-parent, showed off more than three dozen of the “children”—the paintings we treated in preparation for the exhibit. Afterward . . . well, as long as you’ve crossed the big pond you may as well chunnel it over to Paris, so that’s what we did. Main target, the Musee d’Orsay, to compare my recent work on the Clark’s Bouguereau Nymphs and Satyr to the d’Orsay’s equally lavish Bougereau, The Birth of Venus. I was confident I’d done the right thing by removing the thick, discolored varnish layers, but seeing Venus glow with the same alabaster rosiness confirmed my decision. So, time to return to Williamstown, and we are at the airport buying some last minute gifties and Mary turns to me, sheet white, and bursts into tears. She’d just realized her jewelry was back in the safe at the Plaza Athenee. I phoned the hotel and was offered two options, either hire a courier to transport them or come back and retrieve them myself. A courier was excessively expensive and the plane was boarding. What to do? Well, put it this way—several people have congratulated Mary for her unique way of guaranteeing a return trip to Paris! I am writing this now fresh from that return. This time, the highlight was the Edward Hopper exhibition at the Grand Palais, which includes the iconic Morning in a City, owned by the Williams College Museum of Art. I had given this painting a complicated cleaning in 2006, which we described in Art Conservator, Volume I, Number 1. This is a very different nude from the Bouguereau, and in Paris it was on a wall by itself. Now it was my turn for tears­—the picture looked that beautiful. Sometimes life as a conservator is pretty damn awesome! —Tom Branchick

Cover Story

Faces of the Past Restoring the fragile beauty of our earliest photographs By Larry Shutts


he surface of a daguerreotype is as fragile as a butterfly’s wing.” These words were the caution of François Arago in August 1839 when he announced to the world the photographic process perfected by Louis Daguerre. Arago’s admonition is as apt today as it was 173 years ago. The slightest touch of a daguerreotype’s surface will mar or even remove the image. Sliding an even slightly rough object across the highly polished silver will produce disastrous scratches. A single drop of moisture causes a permanent stain. Daguerreotypes have always required specialized housing and care, and traditionally been presented in small cases under glass or large, glazed wall frames. Even housed, though, daguerreotypes are subject to several forms of environmental damage, including tarnish, mold, corrosion of the metal base, atmospheric deposits, and degradation of the cover-glass.

In the worst cases, these degradations can be so great the photographic image is completely obscured. Cases themselves also show the effects of handling. They become unglued, broken, faded, worn, and the covers separated and lost. Yet there is nothing as beautiful as a daguerreotype. The delicate, one-of-a-kind image sits suspended between a plate of mirror-bright silver and protective glass. To fully appreciate its magic, you have to hold it in your hand, rock it, twist it, move it until the light strikes just right and the image seems almost to pop off the surface. The effect is startlingly direct, personal—even intimate. Faces of the past are so real and immediate you almost feel as if you should apologize for staring. The original 1839 process was greatly modified by 1843 to the procedure which was generally adopted by the majority of

The plate was now ready to use. Exposure times were often extremely long, though at the height of the daguerrean era advanced lens technology combined with increased plate speed had decreased exposures from ten minutes to ten seconds. After exposure, the plate was developed using the vapors of heated mercury, which combined with the exposed silver crystals to form an image. The remaining unexposed halide layer was removed and the image “fixed,” that is, rendered impervious to further effects of light. Typically, the image was toned and strengthened with gold chloride, then rinsed free of all chemical residue and dried. Some daguerreotypes received hand-coloring in the form of dry powder pigments applied delicately to the surface. The image was then sealed behind glass and placed in a protective case. While the daguerreotype is considered a relic of a vanished past, the process is still in use today among a small, dedicated group of photographic artists. I am among them, seduced, as are all modern daguerreans, by the medium’s otherworldly elegance. As both a professional conservator and contemporary practitioner of Daguerre’s art, I have a unique perspective on historic daguerreotypes. Much more damage has been quickly and permanently inflicted by the handling of unknowing persons than through elemental decay. I take a very conservative approach to the preservation of historic daguerreotypes, a collection of which was recently brought to the Altanta Art Conservation Center. This collection, which includes early daguerreotypes, tintypes, and ambrotypes, follows an old Southern family through decades of growth, marriage, and generational birth. The earliest daguerreotypes date to around 1843, and document the life a one Mary Warburton Sutton (1831-1905). Mary is seen first as a young girl with her Tintype and ambrotype portraits of the Garnier family, following Mary Sutton’s mother and, in a separate picture, with a marriage to Izador Garnier (top right). Above, Mary and daughter Issie, c. 1905. practitioners. In this process, a thin silver facing was clad to a copper plate and polished to a mirror finish. Polishing was done by hand with buckskin-covered paddles and powdered grits of decreasing size. The finer the polish, the brighter the image produced and the greater the photographic sensitivity. The prepared plate was exposed to vapors of iodine and bromine, forming the light-sensitive crystals that hold the image.

In the Shadow of Bellini Restoring the Yager Museum’s Madonna of the Meadow By Sandra Webber Conservator of Paintings


he name of Venetian artist Giovanni Bellini (14301516) has come down through time synonymous with beautiful religious and mythological paintings, often set in jewel-like, naturalistic views of northern Italy. Of these, he is perhaps best remembered for his serene and reverential depictions of the Virgin and Child. Giovanni, one of a family of painters and eventually a famous workshop master, trained many artists who became famous in their own right, most notably Titian, Sebastiano del Piombo, Cima da Conegliano, and Giorgione, and many other lesser known pupils. Studio replication of the Master’s popular devotional images, especially Mary and Jesus, was fueled by market demand. Keeping to the Master’s compositions and painting style was an important attribute for potential customers. Later artists who never had been directly associated with his workshop also modeled their work after Bellini, as did generations of art students. Many possibilities come into play when examining an old painting that may or may not be directly connected to the master. In 2011, Donna Anderson, Coordinator of the Yager Museum of Art and Culture at Hartwick College in Oneonta, New York, brought in a small (48.5 X 58.7cm) Italian panel painting Madonna of the Meadow, which was undergoing research by K. Michelle Hearne Arthur, the collection’s Consulting Curator. Using the museum’s own files and research, and a proposal and images from the Williamstown Art Conservation Center, Anderson and Arthur applied for and received a conservation grant from the Greater Hudson Heritage Network. Although granting agencies require comprehensive descriptions of the conservation work and the costs involved, this evaluation was partially blinded by the 8 | Art Conservator | Fall 2012

many previous restorations on the surface, making accurate assessment difficult. The projected treatment encompassed a major examination and restoration of what they hoped would be more definitively identified as a Giovanni Bellini workshop painting. The obvious relationship to Bellini’s larger Madonna of the Meadow (circa 1500) at the London National Gallery provided the foundation for the attribution. Although the London picture has a more complex background with a different, closer walled cityscape and farm animals in the middle-ground, the unusual horizontal composition and the principal figures are nearly the same. However, unlike known Bellini workshop multiples, the two paintings were not produced from the same cartoon, the Yager’s version being much smaller than its possible prototype. The Madonna of the Meadow was a bequest to the Yager Museum in 1960 from collector Louis van Ess, who had purchased it in 1954 from art dealer Anacleto Frezzati. In a 1955 article in Arte Figuratura, the painting had been attributed to Bellini, although later scholarship listed it as an “anonymous example.” The painting is structurally stable and now quite flat due to a transfer done in 1954. The original wood support and possibly some of the thin gesso had been removed and the remaining ground and image layers glued down to a piece of quarter-inch Masonite. This was then veneered with oak on the reverse and edges and a mahogany cradle was installed across the back. It is assumed that the Thorp Brothers of New York performed the transfer, as they are recorded in other Van Ess files. It is clear that whoever did this structural work did very little to the aged restorations on the surface. A fabric weave pattern impressed into the thick discolored varnish was likely the result of a facing fabric applied to protect the surface during the transfer process. A few retouches may have been added at this time, but fear was likely the reason no attempt was made to clean and restore the image in the mid-twentieth century. Although larger-than-normal cleaning tests had been opened during the initial examination, the true condition of the paint layer was not understood until later in the treatment.

The surface was literally buried under very thick and heavily yellowed oil-resin varnish, extensive fills, and repainting. Radiography and infrared photographs were done prior to cleaning in hopes of revealing additional construction and condition information. Although the transfer preparation made the X-ray quite blotchy, we were able to make out white outlining following the figures. The numerous losses follow the original wood grain direction in predicable patterns, caused by movement of the wood as it inevitably shrank, cracked, and warped over time. The presence of wood beetle exit holes points to a second source of the panel’s deterioration. The infrared image showed only a few lines in the background buildings and around the hands of the two figures. Although a complete underdrawing incorporating shading is often found on early

panel paintings, simpler methods of transferring outlines to the surface can not be ruled out. Considering my fears about what might be left of the paint layer, I was somewhat timid about beginning the cleaning. As the two layers of deeply yellowed varnish slowly came away, original color details, extensive overpaint, and previously unseen problems were revealed. The primary condition that emerged was massive abrasion to the paint layers, which had blurred the linear detailing and damaged the final glazes. There appeared to be five distinct filling campaigns on the surface, ranging from large extensive brown pigmented wax areas to dense lead-containing white and pale blue putties. Many of these extended down to the level of the original wood, some were layered one on top of another, and quite a few extended over original paint. Once these

fills were removed, a new stronger putty of uniform color was installed. Extensive and insoluble pale yellow overpaint was also discovered on the upper two thirds of the sky, masking what had been a gradation of deep blue above the line of intact pale yellow at the horizon. Overpaint around the Madonna’s head and veil had hidden clusters of damaged delicate halo rays extending into the sky from either side of her head. The surface of the original paint has the soft blended presentation of early oil paint, although Italian artists had only been working with the new oil medium for several decades, often in combination with egg tempera. The delicate linear forms are typical of Bellini’s style and the discreet placement of color within forms is consistent with paintings of the period. During cleaning, Yager Museum staff contracted Richard Newman, Head of Scientific Research at the Boston Museum of Fine Arts, for analysis of the painting materials. Cross sections were taken through selected color zones, those least likely to be contaminated by previous restoration materials. While analysis was under way, the restoration of the painting’s surface began. With the fills leveled and a light coat of varnish applied, an actual state photograph was taken, showing all the losses toned to one color. Although the artist’s ground looked golden in color, it was believed to be an aged sealant on top of the white gesso, applied to lower the gesso’s absorbency. Image reconstruction began with the architecture

and the surrounding landscape. Folds and shading of the Madonna’s costume were slowly pulled together with numerous glazes, relying primarily on the evidence on the surface, but also using the London painting as a guide. Visually her blue robe appeared to be the greenish-blue mineral pigment azurite, and not the exceedingly expensive lapis lazuli visible on the London image. For the blue inpainting, coarse deepblue azurite was hand ground with a stone mortar and pestle, followed by a second grinding between a glass muller and a ground-glass plate. The problematic sky was re-created from the paler horizon tone up to the top edge of the picture in gradated layers of azurite. The previous restoration of the top of the Madonna’s head and veil had extended too high, so I used watercolor outlines to place them in their proper location prior to inpainting. The Virgin’s facial details, marred by damage and still retaining some previous overpaint, had to be slowly adjusted to bring out the gentle original expression. The tilt of her head and the position of her glance were somewhat different from the London painting, whose eyes were shown nearly closed. Fortunately, the expression was close to that of a 1505-1510 Bellini-and-workshop Madonna in the Thyssen-Bornemisza Collection in Madrid. The three small clusters of radiating halo rays and the gold border on the Madonna’s robe were lightly reestablished using shell gold, 24K grains of metal in gum Arabic.

Shortly after the restoration was completed, Richard Newman’s technical report arrived and provided much insight into the picture’s materials. The gypsum ground was comprised of only one layer and did indeed have an aged, medium-rich coating isolating the ground from the subsequent colors. This ground preparation, although a thinner variant than seen on earlier egg tempera panels, is consistent with the emerging oil technique. Lead-tin yellow, Type I was found in the yellow sleeve and the paler green foliage. This pigment is used as a dating aid because the recipe disappeared around 1750, and was not fabricated again until 1941. Although two types of lead-tin yellow were produced, Type I began to displace Type II in Italy during the second quarter of the fifteenth century. Other pigments found were the ubiquitous lead white, found in many locations, Kermes red lake on the sleeve, and grains of vermilion, along with various unspecified earth colors. Copper-based green, possibly altered verdigris that had reacted over time with the oil medium, was found in the foliage. The cross sections through the blue robe revealed mere traces of a lapis lazuli layer, indicating there may once have been a thin glaze of the more expensive blue over the predominant azurite. This minimal use of the valuable blue color, often contractually prescribed for the Virgin’s robes, suggests the picture was not a commissioned work. Although Italian painters of this period often mixed or

layered their oil and egg mediums, as found on other Bellini workshop paintings, analysis suggests the medium here may be oil alone, principally walnut oil. Earlier research at the London National Gallery suggests walnut oil was the primary oil used in Italy in the fifteenth century. Does this mean the painting is somewhat later than Bellini’s lifetime, or just the work of a more progressive disciple working in pure oil? Did the artist have direct access to the London painting or perhaps a drawing related to Bellini’s workshop, or did he see it years later? These questions must remain unanswered for now. The materials and construction of the Yager Museum’s Madonna of the Meadow certainly fall within those expected on a sixteenthcentury Italian panel. The composition and the quiet reverence of the image also reflect some connection to Giovanni Bellini and London’s Madonna of the Meadow. Perhaps further research and intense connoisseurship might one day assign a workshop assistant of Bellini’s as the artist of this small devotional Madonna and Child.

Jasper Cropsey’s Autumn Idyll


n 1968, the University of Maryland Art Gallery mounted a retrospective exhibition of forty-seven paintings and prints by Jasper F. Cropsey, in which the Hudson River School artist was appointed “America’s painter of autumn.” The title was apt. During the second half of Cropsey’s career, from his mid-forties till his death at age seventy-seven, fall landscapes were, with few exceptions, the sole creations to come off his brush. He had produced no small number of autumnal paintings as a younger man as well. One might ask why Cropsey (1823-1900) was so singularly devoted to this motif, but it’s hardly necessary. It is not difficult to imagine a sensibility as reverent toward nature as the Hudson River School finding in autumn the perfect allegory of moral beauty entwined with sublime melancholy. Cropsey embodied everything the Hudson River School stood for: like Thomas Cole, he exploited the allegorical potential of the America wilderness, and like Asher B. Durand, was equally devoted to a precise realism that exalted nature for its own sake. As American landscapes go, there are few more luminous subjects than the region around the Hudson River in October. The 1877 Head of the Lake is typical of Cropsey’s mature style, a confident colorful American idyll, painted with a liveliness that is at once naturalistic and painterly. The painting had been in private hands since it was created, and only recently sold at auction. It arrived at the Williamstown Art Conservation Center discolored by a thick coating of varnish and decades of tobacco smoke, and did not appear to have ever been cleaned or otherwise treated. The heavy, yellowed top coat had been applied over Cropsey’s original varnish, and though it obscured the painting’s luscious chromatics, it also provided an additional protective layer that afforded head paintings conservator Thomas Branchick a rare opportunity to work with a pristine Cropsey paint surface. “Cropsey can easily be overcleaned, which means you can easily remove transparent glazes that add subtle tone and color to his work,” Branchick said. With a specially formulated solvent combination, the Jasper F. Cropsey, Head of the Lake, 1877, after conservator painstakingly removed the smoky brown treatment. Left, detail of the central section. grime to reveal what an art historian once termed Cropsey’s “outstanding merit,” his “freedom of touch [that] . . . gives life to all the objects” in his paintings. “It’s amazing to see the brushwork of the artist, and to observe how he built up the layers and glazes,” Branchick observed. “He employs really thin glazes in the water and the trees, creating an effect almost like halos around the foliage.” With the varnish removed, it is also possible to see the vigor Cropsey applied to his work, in the quick slurs and daubs of the trees, the energetic crisscross strokes of the sky, and the gestural lines that indicate movement in the water. The picture is “one of the more sensual Cropseys I’ve seen,” said Branchick, who has treated several by the artist and other Hudson River painters. Certainly it adds one more layer of confirmation to the claim that Cropsey is our premier artist of autumn.

The identity of this Walter Scott is impossible to ascertain, though it is almost certainly not the celebrated Scottish novelist and poet, whose dates are 1771-1832.

The painting was made on coarse-weave canvas with an earthy red ground, a technique more typical of Italy or France than either the British Isles or the American colonies.

West’s time. Its condition upon arrival at the Atlanta Art Conservation Center was good. Areas of past cleaning were evident in the brightened central figure, but the background was untouched, with much of the original varnish underlying a more recently applied natural resin coating. Under ultraviolet examination, a few areas of inpainting are visible, though the painting remained largely in its original state. A minor, barely visible puncture in the lower center was the only element needing immediate repair. Larry Shutts, head paintings conservator at the Atlanta Art Conservation Center, determined that the best treatment was to keep the existing finish and inpainting materials and merely improve on them. Loose paint in the area of the puncture was consolidated with gelatin and the canvas mended using a polymer fill backed with Japanese tissue. Accumulated dirt and grime were removed and the existing inpainting was further refined. The present varnish, though slightly yellowed, was in good condition and did not require removal, only refreshing with a light spray application of new varnish. The painting is the High Museum of Art’s first by this important American artist. It hangs in the Atlanta museum alongside works by John Singleton Copley, Gilbert Stuart, and other West contemporaries. This article adapted from text courtesy the High Museum of Art.

Up Close and Illuminated: Artist’s Methods and Materials in the Manton Collection1 By Leslie Paisley Chief Paper Conservator Editor’s Note: The Manton Collection of British Art at the Sterling and Francine Clark Art Institute includes more than two hundred paintings, drawings, and prints by Gainsborough, Constable, Turner, Blake, and others, and was the creation of businessman and arts patron Sir Edwin A. G. Manton (1909–2005) and his wife, Florence, Lady Manton (1911–2003). The collection, a gift from the Manton Foundation in 2007, constitutes the most significant acquisition of art by the Clark since its founding in 1955 and complements the Institute’s extensive holdings of nineteenth-century French and American art. In 2010, Leslie Paisley, head of paper conservation at the Williamstown Art Conservation Center, performed a technical survey of the drawings in the Manton Collection, and with third-year intern Mary Broadway contributed an essay on the findings to the 2012 catalog, Landscape, Innovation, and Nostalgia: The Manton Collection of British Art. The essay, titled “Up Close and Illuminated: Methods and Materials in the Manton Collection,” examined the range of supports and media of the Manton works on paper, with detailed descriptions of paper composition, watermarks, charcoal, graphite, chalk, ink, and watercolor. This bulletin, excerpted and annotated with the author’s notes in brackets, illustrates some of the examination’s technical findings and casts light on the working techniques of Thomas Gainsborough.

Figure 1

The eighteenth and nineteenth centuries in Britain witnessed unprecedented inventions in the production of artists’ media, inspiring a wide range of new drawing styles and techniques. Conservators at the Williamstown Art Conservation Center studied the papers, materials, and experimental techniques of works on paper in the Manton Collection, providing insights into the material history of drawing at the time.2 [In addition to determining the order of media application and identifying materials used in execution of the drawings and watercolors in the collection, the process of technical examination yielded many interesting revelations. Inspection of the papers in raking and transmitted light revealed watermarks and other details; examination under the microscope and in ultraviolet light (UVA) revealed applied coatings and subsequent repairs; and, in one case, examination under infrared light revealed an inscription that was key to attributing a work. Examples of these findings are illustrated here in Figures 1 and 7. For a complete description of examination techniques and results, with illustrations, please see the catalog.] Williamstown Art Conservation Center  |  19

The diversity of works in the Manton Collection demonstrates the wide range of experimentation and possibilities in the medium of watercolor that emerged during the second half of the eighteenth and throughout the nineteenth century. [A group of drawings by Thomas Gainsborough provided an opportunity to study in greater detail his working techniques, especially his use of coatings and fixatives.] Fixatives and varnishes were necessary to ensure the stability of the work or to alter its appearance. The term “fixative” refers to a dilute liquid substance generally sprayed or dipped to adhere powdery pigment particles to paper, while “varnish” indicates a natural resin finish, often applied by brush, imparting a gloss. They were added during execution to protect the media from smudging, as well as upon completion to more closely approximate the varnished look of oil paintings. While several watercolors in the Manton Collection contain coatings applied over the watercolor washes, the nineteen Gainsborough drawings in the Clark’s collection provide the largest, most intriguing group for study. Gainsborough considered the fixative process central to the final appearance of his pictures, and used an innovative method, particularly in his application of coatings in layers. The drawings fall into two groups: those with a matte surface, executed in either graphite or black-and-white chalks [with an applied fixative][Fig. 2]; and more fully realized drawings with added watercolor and a glossy varnish [Figs. 3 and 4]. In a letter to his friend William Jackson, Gainsborough imparted his “secret” method of making a drawing look like a painting: Make the black & white of your drawing, the Effect I mean, & disposition in rough, Indian Ink shadows & lights of Bristol [referring to white lead chunks produced in Bristol as opposed to London] . . . when you see your Effect, dip it all over in skim’d milk . . . correct your Effects with Indian Ink . . . dip again. . . . Then tinge in your greens, your browns with sap green & Bistre, your yellows with Gall stone & blues with fine Indigo . . . when this is done, float it all over with Gum water . . . let that dry & varnish it 3 times with spirit varnish such as I sent you; tho only Mastic & Venice Turpentine is sufficient. . . .3 In an effort to better understand the layered structure of Gainsborough’s more complex, coated watercolors, initial research and analysis was carried out at the Williamstown Art Conservation Center on a group of four varnished drawings. They fit the criteria of the study not only because they appear to have been executed with similar materials and methods, but because they all contain thickly applied white media in need of consolidation, which provided open sample sites. The drawings were divided into pairs. One pair was acquired by Sterling and Francine Clark in the

1910s, the second was part of the Manton bequest. At first glance, it was clear that the first [Clark] pair, Herdsman and Cattle and Landscape with a View over a Distant Plain [Figs. 5 and 6], were significantly less yellowed than the second [Manton] pair, Landscape with Figures, Herdsman and Cattle at a Pool, and Distant Church and Wooded Landscape with Figures and Winding Track Leading to a Cottage [Figs. 3 and 4]. Examination of the paper, media, and coatings confirmed much of Gainsborough’s description of his working technique.4 The artist in all four cases selected a fine quality, laid, linen-and-hempfiber writing paper, sized with gelatin. Gainsborough used graphite for the preliminary underdrawing, charcoal for linear detail, and stumped or smudged portions of the charcoal with a tool to infer the darkest darks and midtones. At this point, he brushed a plant-based gum, such as gum arabic, gum tragacanth, or almond gum, on the drawing, and then dipped it in skimmed milk depending on the friability of the media. This initial fixative held the charcoal in place and prevented it from sullying the white highlights, which were applied next. When working in dry media, Gainsborough preferred an opaque dry lead- or calcium-based white chalk, which he referred to as Bristol after its place of origin. In cases where dry and wet media were combined, Gainsborough applied the whites thickly; in some instances he may have done so directly from a tube of paint.

Fig. 7: Thomas Gainsborough, detail of Wooded Landscape with Figures and Winding Track Leading to a Cottage, mid- to late 1780s, as viewed under ultraviolet light (UVA). The top and bottom right corners each exhibit a curved area of little to no fluorescence. This indicates that one or more artistapplied coatings are absent from these areas, possibly where the paper was held or clipped while dipping.

Once laid in, the highlights needed to be fixed to preserve their opacity and vibrant, fluffy quality. This fixative was likely the skimmed milk to which he referred in his letter. Preliminary cross-section analysis using fluorochrome dyes and visual evidence support this supposition. Using milk as a binder provided a film of natural fixative that would have been relatively tough and almost transparent once dry. For its application, Gainsborough preferred dipping, evidence of which became apparent when the drawings were viewed under ultraviolet light (UVA), showing areas the approximate size of a person’s thumb [Fig. 7], which likely indicate where the artist held the sheet of paper as it was gently submerged. Following the milk fixative, Gainsborough laid in any colored washes, first the yellows, browns, greens, and blues, then ending with reds and oranges, which were often vermilion based. This structure is confirmed by other drawings, in which the pigment can be seen applied on top of white, and in which the lead-white highlights are protected by a skim milk coating. Once the composition and colors were in place, the decision to varnish the drawings to make them look more like oil paintings was presumably made based on the quality of the work and its intended status and audience. For the varnish, Gainsborough preferred mastic resin and Venice turpentine, which could be brushed over the surface of the drawing. Often, more than one coat was used, producing an effect like an oil painting. Over time this natural resin varnish has yellowed and developed a fine crackle pattern, more so on the two works that received more light exposure. Future analysis on these coatings may help determine the exact composition and placement of the coating layers. A true microcosm of British drawings from the eighteenth and nineteenth centuries, works from the Manton Collection will continue to excite further research and examination over time. As paper conservator Marjorie Shelley observed about her conversations with Sir Edwin: “What I remember about him most of all was his enthusiasm for works of art . . . and his curiosity about the materials and techniques. . . . He was a truly unique [collector] in that regard. . . .”5 How fitting then that we include a consideration of process and materials with this catalog. The mysteries these sheets have to reveal will continue in Williamstown and beyond. 1 Excerpted from Clarke, Jay A., ed., Landscape, Innovation, and Nostalgia: The Manton Collection of British Art (Williamstown: Sterling and Francine Clark Art Institute, 2012). 2 Susannah Blair, Research Assistant, Department of Drawings, Getty, and Jay A.
