40th International Symposium on Archaeometry

The 40th International Symposium on Archaeometry (ISA) was held earlier this year in Los Angeles (May 19-23, 2014). The first two days of the conference took place at the Getty Villa, and was then moved to the California NanoSystems Institute (CNSI), UCLA for the remainder of the symposium. There were over 300 scholars and students from all over the world who took part in the conference, with diverse research backgrounds including archaeology, conservation science, art history, materials science and engineering, chemistry, geoscience, and physics.
The symposium covered the following major sessions: “Stone”, “Plaster and Pigments”, “Ceramics, Glazes, Glass and Vitreous Materials”, “Metals and Metallurgical Ceramics”, “Archaeochronometry and New Trends in Luminescence Dating”, “Human Environment and Bioarchaeology”, and “Remote Sensing, Geophysical Prospection and Field Archaeology”. Many important and new research results were presented during the talks followed by Q&A sessions and panel discussions. Over 200 posters were presented at the Getty Villa and UCLA during four poster sessions related to the different session themes.
Two keynote presentations were given during the symposium. Dr. Ian Freestone (Institute of Archaeology, UCL) gave a talk on the use of different archaeometric methods and techniques to identify and determine production events and provenance the organization of production of archaeological materials. During his talk, he presented several interesting case studies on ceramics, glass and metals, which were very informative and instructive. Dr. Terry Brown (Faculty of Life Sciences, University of Manchester) reviewed the history of ancient DNA (aDNA) research in biomolecular archaeology. In addition to successful case studies where aDNA sequencing was applied to ancient human remains, he also discussed the current limitations and challenges of this research, as well as future trends.
For the first time at the symposium, a themed session on “Forensic Science Investigations in Art and Archaeology”, chaired by Dr. Ioanna Kakoulli (UCLA/Getty Conservation Program and Materials Science and Engineering Department at UCLA) was introduced. This special session focused on the challenges and technological difficulties pertaining to forensic science investigations in art and archaeology. Topics covered included the recovery of artifacts, the criminal investigation associated with looted artifacts requiring material characterization, identification and provenance of looted objects, and repatriation of looted antiquities. Agnieszka Helman-Wazny (University of Arizona) talked about the use of fiber analysis to trace manuscripts with unknown origins from the Silk Road. Patrick Boehnke (UCLA) presented preliminary results on the use of strontium isotopic and elemental analysis by secondary ion mass spectrometry (SIMS) to help the Dept. of Homeland Security provenance looted glass artifacts with unknown origins and heterogeneous compositions. Dr. Ernst Pernicka (Curt-Engelhorn Zentrum Archäometrie and University of Heidelberg) gave a talk on the analysis and authentication of the Sky Disc of Nebra through various scientific methods and approaches. Dr. C. Brian Rose (University of Pennsylvania) reviewed the case of the Troy gold in the Penn Museum for which a repatriation claim was filed by Turkey. Lastly Dr. Timothy Potts (J. Paul Getty Museum) gave a thorough review on the evolution, over recent decades, of U.S. museum practices and policies relating to the acquisition of antiquities, as well as the issues of authenticity and conservation analysis that are involved. Unlike other sessions at ISA, the forensic science session did not have a Q&A at the end of each talk but instead held a panel discussion with all five presenters and the session organizer/moderator. One of the more lively discussions focused on the analysis of archaeological objects from collections with little or no provenance. A debate arose as to the value of analyzing these materials that lacked archaeological context. Issues with the authentication of antiquities without context were also brought up, as well as the role this analysis plays in the looting of artifacts and the illicit antiquities trade.

Though there was no session specifically focused on topics related to conservation and preservation, there were many papers of interest to those in our field. The North American conservation graduate programs were also well represented. Faculty, conservation students and researchers affiliated with the UCLA/Getty Conservation Program (https://uclagettyprogram.wordpress.com/2014/05/19/isa-2014/), Buffalo State College (http://artconservation.buffalostate.edu/publications), WUDPAC, and Queen’s University presented papers and posters, and moderated sessions. The abstracts of all the ISA presentations can be found here: http://www.archaeometry2014.com/wp-content/uploads/2014/05/ISA-2014-Program-and-Abstracts-Book-Online.pdf
ISA 2014 introduced attendees to many interesting topics related to the analysis of archaeological objects and archaeological research. The most recent key breakthroughs in archaeological science were presented. Fruitful discussions on current limitations and challenges were conducted, and innovative ideas on future research trends were exchanged. The symposium provided an open and friendly panel for scholars and students from different research backgrounds and countries to participate and communicate in this interdisciplinary field of study.
The next ISA conference will take place in the spring of 2016 in Kalamata, Greece offering a beautiful and relaxing place (by the seaside) to learn about the latest archaeometric research. We hope to see you there!

The Movie "Art and Craft": A Conservator's Perspective

Conservators have an uneasy relationship with forgery. Often knee-jerk reactions arise: outrage, indignation, feelings of being duped, and sometimes a closet admiration of a particular craft skill. While certainly valid, and generally true, they can be somewhat of a conversation stopper. Deep down, I find myself a bit envious that forgers get so much media attention, and that this attention is generally overwhelmingly sympathetic. Conservation is just as interesting, right?
Some examinations of philosophic aspects forgery within the field of conservation include AIC’s 2007 Annual Meeting, “Fakes, Forgeries and Fabrications” and tangential papers like conservation rock star Salvador Munoz Vinas’s 2011 “The Frankenstein Syndrome” in Ethics and Critical Thinking in Conservation. Once, I discovered a forged portion of a Gutenberg Bible I was working on, thankfully it belonged to an institutional client, rather than a private one.  Since we spend a lot of time looking at very small things, maybe it is difficult to change perspective, take the optivisor off, and look at this issue a bit more broadly.
The movie Art and Craft tells the story of Mark Landis, a contemporary forger. It is an entirely enjoyable film, the directors allow Landis to show and tell his story with little interference. The film clearly articulates his reasons and motivations for forgery while not becoming overly romantic. Landis, a diagnosed schizophrenic, is shown visiting his therapists and at home, generally watching tv and copying pictures from art books at the same time. He is quite likely more a victim of “the system” more than someone taking advantage of it. A couple of times he is shown engaging in quotidian activities; eating a dinner of melba toast dipped into a container of margarine, for example.

Early on, the film reveals his primary motivation for creating forgeries: he wants to be a philanthropist. But he realizes quite quickly it is hard to be a philanthropist without money or art to give away; he had to create the art in order to distribute it. Also, he liked being treated like a philanthropist, and he admits becoming addicted to it. Who wouldn’t? So he keeps making more forgeries. The film delves into his personality, much of which seems to be strongly influenced by a tv that always seemed to be on. He is self-aware of these influences, and tells others of their source. For example, he started smoking because he saw characters in 1940’s movies smoking to calm down, so he thought it would help calm his nerves, and curb his compulsion to pace.

The film emphasizes the naturalness, almost an innocence, of his desire to copy works of art. The motivations behind many forgers (which are generally not pecuniary by the way) are often egotistically motivated: proving oneself equal to the great artists or “getting even” with the art experts by exposing their ignorance. In addition to his philanthropic desires, Landis also simply likes to copy things, again because it calms him down. Repetitive hand motions and using hand-eye coordination is comforting to him.  Sound familiar?

The antagonist in this film is a Matthew Leininger, a museum registrar, who originally noticed a number of identical paintings in numerous museums, and over the years slowly closed in on Landis. When seeing some of the paintings, the audience wonders how they could have fooled anyone.  Many are not of Eric Hebborn or Elmyr de Hory caliber, though Landis is certainly capable of finely crafted work. Many of his forgeries are a color photocopy of a work with acrylic medium smeared on the surface, to resemble brushstrokes. The materials he uses are all standard off the shelf art supplies from Michaels, and the frames from Home Depot, though he slightly antiques them. He often photocopies a certificate of sale from a major auction house or defunct gallery to aid in establishing provenance and adheres this to the back.

In Think Coffee, a coffee shop near the Angelica Film Center in NYC where I saw the film, an original Mark Landis painting hangs. In this case, he has signed his own name, and the price tag is $25,000.  When I saw it, there was no red dot on the label. The painting is hanging in an ordinary wall space above a seat. I hesitate to call it a forgery, since it would be impossible, I think, for anyone to confuse this with the real thing. It looks like a color photocopy with acrylic medium and some painted additions, though the light is pretty low. Is it a forgery of a forgery? Or a copy of a copy? Or just a photocopy with some paint on it?

Landis is quite cavalier concerning his lack of interest in technical details. In an online reddit interview he dismissively leaves it to others. “And as far as artists that use brushstrokes, it’s something I never really gave much thought to. Experts supposedly can tell things like that, an expert is just someone who knows a great deal about something and sometimes he’s right.” And what does it say about our culture that many museum professionals don’t bother to look closely enough to tell a photocopy from a painting? Is it the result of looking at most things reproduced through a computer screen? To be fair, the film does show other examples of his work, drawing and paintings, that are very skillfully executed.

Typical of Landis, he spins a variety conflicting press reports about his work, even the copy of Mona Lisa on display. Was it was painted in 90 minutes as is generally reported or did it take an entire weekend? If sold, will the proceeds benefit the museum in his hometown, the Lauren Rogers Museum?  The museum’s marketing director denies this is true. Again, according to the reddit interview, the most one of his paintings has sold for is $800.

Here we enter an interesting terrain: Landis, who by copying so earnestly, and seemingly created by his media environment, may convolute some of the Benjaminian notions of the aura of authenticity and the copy.  He compulsively recreates copies of copies, over and over, quite likely unable to stop despite protests and essentially being caught. Landis himself admits he has not seen most of the works he copies, only reproductions. There seems to be no authentic work to be copied in his world. He becomes a Warholian performance artist, quite possibly the value of his work in is the transactions, and the changes in perception of the value of his work: genuine, forgery, doesn’t matter?

Landis does not confine himself to assume the persona of a wealthy philanthropist, there are references to at least three other characters he portrays.  In one hilarious scene (shown in the trailer below), he is dressed as a catholic priest, and shown blessing a unknowing recipient.

A question that comes up in the movie that is often asked of forgers—in fact, sometimes restorers and conservators— is why don’t you create your own work?  Landis is charasticly straightforward when he replies that he doesn’t have anything he wants to paint, he just likes copying others work. It is hard for the viewer to resent him. Indeed, he wants come clean, and earn a living based on his skills, as his website selling copies of photographs indicates. A charcoal or pencil drawing starts at $250, and a painting in acrylic or oil is $650.  There is an interesting caveat you must click:  “I certify that the photos provided are owned by me and do not represent an attempt to commit a forgery of copyrighted work.” Good idea, an invitation for more forgery, or a bit of bravado?

I left the movie feeling his forgeries were not only harmless, but in fact a positive thing: he really was making people happy by giving them gifts, and he seemed to get pleasure from it. What more could we ask from a transaction?  Leininger, the registrar, is presented as the killjoy. And even though Landis has tentatively agreed not to gift forgeries to institutions, the movie ends with him headed in a new direction, with similar ethical questions and even less accountability.

Forgers and magicians are experts at misdirection. Landis even compares himself to a magician at one point, when someone asked how he painted his Mona Lisa. “Well, it’s like a magic trick you know. If I told people, it wouldn’t be worth anything anymore.” Has Landis manipulating the director to miss the essential elements of his ethical, if not legal crimes? Could this entire film be considered a meta-forgery, where the viewer is the one duped? The thought even crossed my mind that he might produce obvious forgeries in order to continue producing more sophisticated ones.

Art and Craft provides an entertaining and engaging conversation starter for a number of issues surrounding forgery.

From Italy to Antarctica: Archaeological Conservation on the Web

View of Tumulus MM at Gordion, Turkey
It’s summer (at least for a few more weeks) and for many of us, that means travel.  Some conservators take travel one step further and fly around the world to do archaeological conservation at active excavations.  Luckily for us back at home, many of them are blogging about their experiences.  Here’s a roundup of several archaeological conservation blogs.
The Mugello Valley Archaeological Project/Poggio Colla has a long tradition of blog posts, going back to the late 90s – before they were even called “blogs.”  Recent posts from conservator Allison Lewis can be found here.  I love the use of RTI on incised bucchero sherds, as described by Poggio Colla intern and current UCLA grad student Heather White.   Earlier posts from Poggio Colla can be found in the MVAP archives.
Turkey seems to be the center of archaeological conservation blogs – it must be all the strong coffee and tea!  The conservators and interns at Gordion, where I was lucky enough to work one summer, blog about their time working at the ancient Phrygian capital here.  This post really captures the feel of village life in central Anatolia.  A great conservation-related post is this one about the on-going conservation of two Roman altars rescued from a nearby river.
Nearby in Turkey, the conservators at Kaman Kalehoyuk blog about their experiences at the Bronze Age and Iron Age site.  This post makes nice use of a digital microscope in examining and sharing pictures of artifacts.  Rounding out blogs about the Mediterranean world, the Kelsey Museum of Archaeology Dig Diaries are no longer being updated, but the archived posts still make for interesting reading.
The prize for the blog from the most exotic location, although certainly not the warmest, goes to the tough conservators of the Ross Sea Heritage Restoration Project in Antarctica, run by the Antarctica Heritage Trust.  They are doing some amazing work, like the conservation of these newspaper fragments under challenging conditions.
Close to home and happily active again after a temporary closure because of funding, the conservators at U.S.S. Monitor Center are blogging about their work conserving the massive remains of the Civil War ironclad.  This post gives one an appreciation for the complexity of working on such a large object.
That’s it for now.  Stay tuned for a future post about museum blogs focused on archaeological conservation.  If I missed a blog, feel free to let me know in the comments or via MemberFuse.  And I’d love to see more blogs started, especially about archaeological conservation in other parts of the world such as Asia or South America.

42nd Annual Meeting – Book and Paper Group Session (BPG), May 30, “Salvage of Paper Materials from the Flooding of São Luiz do Paraitinga” by Fernanda Mokdessi Auada

 On Friday May 30th, Ms. Fernanda Mokdessi Auada presented an account of the joint salvage effort undertaken by the Nucleus for Conservation of Public Files of São Paulo (APESP) and the Nucleus of Restoration-Conservation Edson Motta, Laboratory del National Service for Industrial Apprenticeship (NUCLEM-SENAI) following the 2010 flooding of São Luiz do Paraitinga, Brazil. Collective gasps went up from the audience as Auada showed photographs of the devastated city. Among the images was the city all but subsumed by the Paraitinga river, and shots of devastating structural damage to the city’s principal church (São Luiz de Tolosa) and its municipal library.

Thousands of documents, over 15 linear meters in total, were immersed in the flood waters for over 20 days. The papers related primarily to the population’s citizenship and legal identity, making it vital for conservators to save the information contained in the wet and moldy files. Despite the grave condition of the documents–and the challenge of having virtually no money or trained support staff–the overall salvage was a success, Ms. Auada said.

The documents arrived for salvage in three allotments. The first two allotments were treated manually, using traditional flood damage salvage procedures. First, the documents were separated and air dried flat on top of absorbent paper. The documents were then individually documented and inventoried during dry cleaning, these steps carried out in a dedicated cleaning area. Documents that could not be separated mechanically after drying were separated while immersed in an aqueous bath. Papers soiled with heavy accretions of dirt and mud were washed to recover legibility. The papers were then mended, flattened and rehoused in paper folders and corrugated polypropylene boxes. Incredibly, 95% of the documents in the first and second allotments were recovered.

The third allotment, from the Public Ministry, proved to be more problematic, calling for radical treatment. These documents arrived at the APESP three months following the flood, after having been stored wet and housed in garbage bags. Upon drying the materials, it was determined that the extensive mold damage would be impossible to treat using traditional methods. Representing a “worst-case” scenario, this allotment of 176 files was submitted to decontamination by gamma irradiation. The moldy documents were packed in corrugated cardboard boxes and sent to the Radiation Technology Centre for Nuclear and Energy Research Institute (CTR-IPEN) at the University of São Paulo. While still within the cardboard storage boxes, the documents were dosed for disinfection (not sterilization) at 11kGy. This was the first time this type of salvage procedure had been carried out in Brazil.

Following irradiation, the papers were separated and dry cleaned using brushes. The dry removal of the mold spores proved easier and faster than the first two non-irradiated allotments, with sheets separating easily. Perhaps most importantly, the biohazard was eliminated, eliminating the need to quarantine the documents during documentation and dry cleaning. Ms. Auada described the costs of the treatment as acceptable, even within the project’s meager budget. The irradiated documents will be monitored for long term effects of the radiation, with polymerization of the cellulose being of primary concern.

42nd Annual Meeting – Textile Session, May 30, “Stressed about Pests? A Panel-led Discussion on Integrated Pest Management” Moderators: Bernice Morris, Patricia Silence, Rachael Arenstein.

This session included three presentations on Integrated Pest Management (IPM). The first speaker, Bernice Morris, is the IPM coordinator at the Philadelphia Museum of Art (PMA.)   Bernice said that IPM began in earnest at the PMA in 1990. She has built on this foundation, developing an IPM system consisting of dividing the museum into risk zones, the use of barcoded (numbered) blunder traps (with pheromone lures as needed), and iPhones outfitted with barcode readers. The iPhones scan the bar code on each trap. The pest type and count are entered, and the data is sent to a computer, becoming a row on a spreadsheet. This makes the gathered data accessible for analysis. The number of traps and the frequency of monitoring are dependent on zone type. In addition, all museum staff are now aware of the importance of prevention and vigilance. The staff has a “bug hotline,” and Internet reporting for pest sightings. It is a very low cost system with the exception of the iPhones, and for those with moth problems the pheromone lures are expensive but worth the investment. The textiles in the collection are most vulnerable while moving in and out of the galleries, and the museum. New acquisitions and loans come into the museum wrapped in plastic. They are isolated and examined, and if evidence of infestation is found the objects are treated with low temperature treatment or anoxia treatment to kill all insect life stages of the infestation.
 
Patricia Silence is the Conservator of Museum Exhibitions and Historic Interiors at the Colonial Williamsburg Foundation (CW). As she said it is “the oldest and largest outdoor living history museum in the United States.” CW had always depended on outside pest management professionals. She and her colleagues developed a vision of what a successful IPM plan would accomplish: “prevent harm to people, collections, and buildings, use minimal pesticides, and foster a sense of ownership of the IPM program in the foundation employees.” Due to the complicated interconnected nature of the collection, architecture, landscaping, livestock, commercial entities, and residences, it was determined that it is would be best to have someone who was on the CW staff to manage the IPM. Ryan Jones was hired as the integrated pest management specialist. The IPM has been so successful the program has expanded to include monitoring and treatment of termites. He and an army of other staff members have certification for pesticide application, but housekeeping, routine trap monitoring, and building inspections and maintenance reduce the need for pesticides. A holding room, and freezing and anoxic treatments are used for objects with infestations. The staff can report pest sightings via intranet; identification sheets with common pests are made available with a pest specific follow-up sheet sent after identification. Patricia has taken a holistic approach.
 
Rachael Arenstein is currently the conservator at the Bible Lands Museum in Jerusalem, Israel. However, as a former conservator in private practice she spoke about some of the challenges she noticed with smaller museums that lack IPM plans. She felt that the biggest problem was most often that pest damage is not recognized and is thought to be the natural effects of age or light damage. Rachael pointed out that all museums have some kind of pest problem. Small museum are understaffed, under-resourced, collections are crowded, and if there is an infestation the staff is just “grossed out.” Mistakes are made using inappropriate products and procedures.   Rachael is a member of the IPM Working Group, which grew out of colleagues banding together to learn how to deal with infestations. Over the past ten years Rachael and these colleagues have created an invaluable resource, Museumpest.net. It is everything one might want or need to know about IPM: prevention, monitoring, identification, treatment solutions, and implementation of an IPM plan, and more. Through the site you can join the Pestlist, an e-mail distribution list that allows members to ask questions, and receive answers and advice from museum and preservation professionals, entomologists, and other practitioners.
 
The speakers opened the floor to questions and discussion. The first question was concerned with how to get the staff to “buy into” the importance of protecting the collection. The reply to this was that presentations to staff showing damage, or potential damage were helpful. Unfortunately, it often takes a major infestation to drive home the importance of IPM. Other questions were asked about pheromone traps, how to handle a museum wide dermestid infestation, if there were any lasting effects from the use of Vikane fumigation, and “are crack and crevice” treatments of any use. The answers were helpful, but too lengthy to address here. All roads lead to http://museumpests.net (and housekeeping.)
