Jamweek – Merkacha – מרקחה:
In late February and early March, Prof. Koren participated in the 4-day “Merkacha” Jamweek workshop at Shenkar that combined engineering and design students who dyed silk scarves with natural dyes and created individualistic artistic designs. In addition, the participants also dyed woolen fabrics with these natural dyes and these pieces were combined to show the needed unity of our society composed of individual entities – “The United Colors of Shenkar”.

artarchaeology2016-logo A fascinating multidisciplinary international conference on Art & Archaeology took place in Jerusalem, Israel, from December 11–14. Prof. Koren was on the Steering Committee and the Scientific Committee of the conference, served as the chair for two sessions, and presented a paper titled: A New Archaeometric Method for the Fast Non-Destructive Identification of Molluskan Purple in Textile Dyeings. The conference highlighted frontier scientific analyses applied to art and archaeological findings. The following is from the welcoming statement found on the home page of the conference website (www.art-archaeology.com):

“The main objective of Art&Archaeology2016 is to advance the frontiers of scientific knowledge connected with human cultural heritage. Heritage is our legacy from the past. It is our source for understanding the human mind, its capabilities and potential. Knowledge of the past influences our present day life and what we pass on to future generations.
Art&Archaeology2016 aims to bring together a range of scholars, specialists and experts in the fields of archaeology, art, history, preservation, restoration and reconstruction of museum or archaeological objects, cultural heritage, researchers of ancient structures and measurement scientists and technologists. Cultural heritage is characterized by time-spatial scales and a wide range of technologies are applied to understand and preserve our archaeological, historic and artistic patrimony.”

One of the talks was given by Prof. Antonia Moropoulou (see picture below), from the School of Chemical Engineering, Section of Materials Science and Engineering, at the National Technical University of Athens, Greece. She gave a detailed presentation on the recent renovations of the Holy Aedicula of the Holy Sepulcher in Jerusalem; this work is sponsored by the Greek Orthodox Patriarchate. In attendance was His Beatitude, Theophilos III, Patriarch of the Holy City of Jerusalem (second from right, holding the scepter) together with the Elder Secretary-General, Archbishop Aristarchos of Constantina. In the center is Prof. Amos Notea, chairman of the conference.

ambix-coverThe renowned dyeing expert, artist, and scholar, Isabella Whitworth of the UK, and Prof. Koren published a landmark paper titled “Orchil and Tyrian Purple: Two Centuries of Bedfords from Leeds” related to their discovery of a century-old molluscan Tyrian Purple dyeing, which is the most modern historic sample yet found. The 24-page article also offers a fascinating insight into the scientific connections and achievements of several generations of a family of dye manufacturers from nineteenth and twentieth century Leeds, and weaves together chemical and dye histories, scientific curiosities, and modern chromatographic analyses. The article was published in  Ambix – The Journal of the Society for the History of Alchemy and Chemistry (SHAC). The journal’s name “Ambix” is from the Greek word ἄμβιξ, a still-head, a vessel used in distillations.

Prof. Koren appeared in Nails of the Cross, the first episode of an internationally-televised documentary series in history and archaeology titled Biblical Conspiracies, which was produced by the Canadian documentarian, Simcha Jacobivici. The show’s website describes the series in the following words: “Biblical Conspiracies is an unceasing pursuit of stories hiding in the codes and symbols left behind by those with a secret to keep. Each hour-long episode sets out to investigate an unknown story discovered within a genuine, undisputed artifact. Using unique graphic-novel style animation, highly stylized CGI, lavish recreations and cutting-edge forensic science, this series explores the time period in which the artifact existed and what it meant to the people who treasured it. For thousands of years, alternative truths have been hiding in plain sight, locked away with secret codes and symbols whose meanings were known only to the initiated…until now.”

Prof. Koren gave a talk at the 33rd Annual Meeting of Dyes in History and Archaeology (DHA33), which took place in October at the University of Glasgow, Scotland, home to a significant number of historically famous scientists, such as Lord Kelvin (1824 – 1907).  Lord Kelvin, who’s original name was William Thomson, was Professor of Natural Philosophy at the university. For all of his remarkable scientific achievements and inventions he was knighted by Queen Victoria in 1892 as the Baron of Kelvin, and was later elevated to the House of Lords. His title refers to the River Kelvin, which flows near his laboratory at the university. Kelvin’s name is immortalized by the Absolute Temperature Scale which uses degrees in “kelvins (K)” in order to report the temperature. Though a lower limit to temperature was already known, Lord Kelvin is credited with determining its exact value to two decimal places as –273.15 oC, which is thus known as the Absolute Zero of temperature, i.e., 0 K.

Prof. Koren’s talk was titled “New Revolutionary Chemical Insights Regarding the Ancient Purple Dyeing Process and Pliny’s Ultimate Decipherment”. The presentation described landmark changes in our previously thought of notions regarding the chemical processing of the ancient purple pigment produced from certain sea snails. These revolutionary insights were discovered by understanding this ancient technology in light of modern chemical principles.

In September, Prof. Koren was an Erasmus Mundus Visiting Scholar in the EMAIL II Program sponsored by the European Union at the Politecnico di Torino in Italy working in the Department of Applied Science and Technology (DISAT) with Prof. Bruno DeBenedetti and his research team.  Part of the research project involved targeting various culturally important heritage objects housed in museums in the city of Turin that would be valuable to scientifically analyze. Towards this end, Prof. Koren surveyed the ancient 1,500-year old Coptic textile collection at the Palazzo Madama Museum and 4,000-5,000 year old Egyptian textiles at the world-renowned Egyptian Museum (Museo Egizio).
