  • Revesz decodes ancient sphinx’s mysterious message

    Revesz decodes ancient sphinx’s mysterious message

    [ad_1]

    Newswise — For nearly two centuries, scholars have puzzled over an inscription of just 20 characters, cast upon an unusual bronze sphinx statue believed to have originated in Potaissa, a Roman Empire military base camp located in present-day Romania.

    Peter Revesz, a University of Nebraska–Lincoln expert in computational linguistics, recently made headlines in approximately 50 news articles from around the world when he solved the mystery.

    “Lo, behold, worship! Here is the holy lion!” is his translation, revealed in the January issue of Mediterranean Archaeology and Archaeometry. Based on his experience using databases to compare and identify alphabet symbols and languages, Revesz concluded the inscription uses an archaic Greek alphabet to convey words in a proto-Hungarian language.

    In addition to the Miami Herald, stories about Revesz’s discovery appeared in Arkeonews, Archaeology News, Greek Reporter,  Stile Arte and GEO.fr.

    A crucial clue to identifying the alphabet was the realization that, not only was the inscription written right to left, but its characters were rendered as mirror images of alphabetic symbols.

    Once Revesz identified the language as an ancestor of Hungarian, the puzzle pieces fell neatly together. He recognized that the inscription uses deliberately alliterative language in a poetic meter – an accented syllable followed by two unaccented syllables.

    “This is what I think is a poem,” Revesz said. “It fits together with the statue itself, a winged lion. It seems to be relaying a prayer line or perhaps a hymn of a minority religion.”

    The statue’s base included a spike for it to be inserted into a pole, which possibly allowed it to be used in religious processionals as a flagpole or standard bearer, Revesz added.

    A member of UNL’s computer science faculty since 1992, Revesz describes himself as an interdisciplinary scholar. He holds a courtesy appointment in the university’s Department of Classics and Religious Studies.

    Revesz said his work is an example of how computational techniques can be used to understand history and language. Another example of the growing field of study is when Nebraska computer science major Luke Farritor used artificial intelligence to decipher words on a charred papyrus scroll that was nearly destroyed in the eruption of Mount Vesuvius in A.D. 79.

    Revesz has loved ancient history and language since he was a child. He credits Paris Kanellakis, his doctoral adviser at Brown University, for fostering those interests.

    Kanellakis was a renowned computer science scholar who was also fascinated by the undeciphered ancient writings of the Minoan civilization. On his desk, he kept a replica of the Phaistos Disk, a Minoan artifact that was covered on both sides with a spiral of stamped symbols. Revesz, who began deciphering ancient inscriptions in 2008 while teaching at the University of Athens as a Fulbright visiting professor, later used computational linguistics to decode the inscription on the Phaistos Disk as a hymn to a solar deity. Also using computational linguistics and mathematical methods, Revesz discovered that the Minoans wrote much about nature, female deities and cave spirits on 28 Linear A inscriptions. Kanellakis tragically died at age 42 in the 1995 American Airlines Flight 965 crash in Colombia and did not live to witness these exciting developments.

    Deciphering the Potaissa sphinx offers insights about minority religions during the Roman Empire, as well as how widespread the Egyptian-derived sphinx cult became before Christianity grew dominant, Revesz said.

    “The translation not only satisfies many researchers’ curiosity, who have pondered this artifact over decades, but it contributes to a broader understanding of cultural life in the Roman province of Dacia (where Potaissa was located) in the third century,” he said.

    Although the sphinx was found in a Roman province, sphinx worship was not part of the mainstream ancient Roman mythology that featured Jupiter, Juno, Minerva and other gods and goddesses that remain familiar to many even today. Revesz said the Potaissa sphinx is evidence that provincial culture was a complex composition of ethnic groups, with influences that could be traced back to Greece and even further to Egypt.

    Many mysteries remain about the little statue, including its whereabouts today. It was acquired by an art collector, Count József Kemény, in the first half of the 19th century, and its provenance is uncertain. The statue disappeared when Kemény’s estate was looted during the Hungarian War of Independence in 1848-49.

    Revesz based his detective work on a detailed drawing of the sphinx and its complete inscription that appeared in Illustrirten Zeitung, an illustrated German news magazine, in 1847.

    In a paper about the Roman Empire’s minority sphinx cult, archeologist Adam Szabó of the Hungarian National Museum wrote that the statue likely was associated with a sanctuary where the Egyptian goddess Isis was worshiped.

    With a female head and winged lion’s body, along with a sun symbol on its chest, the Potaissa artifact bears resemblance to both the sphinx of the Naxians, given by the people of Naxos to the Temple of Apollo at Delphi in Greece, and the Pazyryk sphinx, a central Asian artifact that dates to the Iron Age. In a Youtube video about his research, Revesz describes the dispersion of sphinx and sphinx-like objects across thousands of miles in the Middle East, Europe and Central Asia.

    Romanian archeologist Nicolae Vlassa attempted to translate the inscription into Greek in a 1980 paper. However, Revesz found Vlassa’s translation unconvincing, due to decipherment errors Revesz explains in his research publication. Revesz suspected that, instead of Greek, the inscription used Greek characters to phonetically convey a language that lacked its own alphabet.

    Revesz, who was born in Hungary, noticed that the final six characters, when mirror imaged and rearranged into left-to-right order, resembled “arslan” – a Turkic word for lion that became part of the Hungarian language. Other characters resembled Hungarian words for “worship” and “lo, behold” and an ancient Greek word for “holy”. Some evidence indicates proto-Hungarian speakers were resettled into Dacia after Romans colonized the region.

    “It is well-known that the Roman Empire contained diverse populations and languages,” Revesz said. “Studying this statue feels as if the winged sphinx has flown to us from the distant past and also brought us a message.’”

  • Nebraska team explores ways to expand Holocaust education

    Nebraska team explores ways to expand Holocaust education

    [ad_1]

    BYLINE: Deann Gayman | University Communication and Marketing

    Newswise — On Holocaust Remembrance Day, a large group of University of Nebraska–Lincoln undergraduates stood quietly and reflected near the Nebraska Holocaust Memorial in Wyuka Cemetery.

    Following a talk from instructor Gerald Steinacher, Rawley Professor of History, the students walked along the Sea of Stones representing the 11 million murdered during the Holocaust, read the names of victims with Nebraska relatives on the bricks among them, and took in the information from the Wall of Remembrance. Some walked the path through the tree-lined Butterfly Garden, placed in memory of the 1.5 million children who were systematically killed by the Nazis.

    Maggie Nielsen, a double major in German and advertising and public relations, said the experience at the memorial was moving, especially because she is Jewish.

    “It was really nice to see the responsiveness to the memorial,” she said. “It seems random to have such a thing in Nebraska, when you think about the grand scheme of things, but you realize, looking around and reading the names, there’s good reason for it to be here, and it was touching to see my non-Jewish classmates take part in something so meaningful. It was beautiful to witness.”

    Steinacher asked the students afterward to write a reflection as they sat surrounded by the Sea of Stones and looking up to the gleaming metal, concrete and photos that formed the Star of Remembrance.

    Reflections following experiences like this one, and interactions with second-generation survivors, are a key component to the class, History of the Holocaust, as Steinacher has centered the course design on helping students understand and more fully grasp the atrocities as well as what led up to them.

    And, with the passage of time, that’s becoming harder, he said.

    “We used to be able to bring survivors to class to talk directly with our students and share their stories,” Steinacher said. “That always had an impact by bridging the distance of space and time, but most survivors have now passed away, or are not able to travel because of age or poor health. We’re crossing the bridge between contemporary history — when we can remember things because we lived them — and history, when those who experienced it are no longer here.”

    That fact, as well as rising antisemitism and Holocaust distortion, makes this class, and others like it, all the more important. For the last five years, Ari Kohen, Schlesinger Professor of political science and director of the Harris Center for Judaic Studies, and a team of Nebraska scholars including Steinacher, have been gathering data on best practices in Holocaust education, with the aim of making courses more meaningful and impactful for students.

    “In general, there is a knowledge problem,” Kohen said. “We’ve seen data that tells us students are not learning about the Holocaust. But more than that, we’re seeing a caring problem. The timeliness of this project matters because there has been a dramatic resurgence in antisemitic incidences all over the country.”

    In 2020, Kohen and Steinacher published the first article based in the findings of the pilot study. That article caught the attention of the Conference on Jewish Material Claims against Germany, based in New York, which has funded the research for four years.

    With the funding, Kohen said they will be able to continue the mixed methods approach to learning how to teach about the history of the Holocaust in a way that resonates with students. Students who take the class and opt-in to participate are asked to complete a pre- and post-survey, take part in an interview about the course, and have their written reflections from the class coded and incorporated into the study. With the grant, Kohen said they’ve been able to add research strength to the team, including the addition of expertise from Nebraska’s Methodology and Evaluation Research Core. Kohen also hopes to incorporate alumni of the course into the surveys.

    Most of the findings have lined up with the researchers’ hypotheses — that personal narratives and experiences are the most impactful, which can be realized with book choices and adding experiential learning into the syllabus.

    “Overwhelmingly, students have mentioned the book ‘The Sunflower’ (by Simon Wiesenthal), as something that made them think differently,” Kohen said. “There are excellent historical texts on this time period, but they don’t seem to land the same way — it doesn’t stick with them.

    “We’ve found there is something really impactful about the field trips, where students have visited a synagogue or the Holocaust Memorial or have had the opportunity to meet and speak with people who are Jewish. It seems like common sense, and things we’ve known as educators, but having quantitative information that shows these things work could help educators design more impactful courses everywhere.”

    The funding will help cover costs to host a conference for educators in the future to talk about the findings and how to translate these best practices to both high school and undergraduate college courses. Kohen expects the team to welcome educators for these conferences in the final two years of the grant.

    For students like Nielsen, the assigned readings, field trips, reflections and hearing personal stories have helped her delve much deeper into her understanding of the Holocaust.

    “With my background in German, and being Jewish, I had preconceptions and notions that I knew everything about the Holocaust, but this class has challenged those notions and made me rethink how I approach this era,” Nielsen said. “We read the book ‘Ordinary Men,’ which was about people who weren’t targeted, but were still affected because they were forced to become perpetrators. I had always assumed that they were willing, joyful participants, but I’ve realized many were doing what they thought they had to do to not become another target.”

  • Researchers transform popcorn into microbiome-boosting superfood

    Researchers transform popcorn into microbiome-boosting superfood

    [ad_1]

    Newswise — A Nebraska-led coming attraction may soon pop into a global blockbuster.

    Through a decade-long project supported by Conagra Foods, a University of Nebraska–Lincoln research team led by David Holding has naturally bred new varieties of popcorn that outperform today’s most popular kernels in their intrinsic nutritional value and taste.

    “When we took on this challenge, I was 50% confident that we could deliver on improvements in terms of nutrition,” Holding said. “But at no time did I think this would lead us to a level of success that also delivered improved taste, texture and prebiotics over conventional popcorn.”

    The Nebraska-made varieties — which are currently being tested by Conagra — offer nearly twice the level of lysine, an amino acid essential in the diets of humans and livestock, compared to popular popcorn varieties and other cereal grains.

    Higher lysine can enhance nutritional value, thus adding economic value and broadening the appeal of the popular snack, Holding said.

    Dent corn, a worldwide crop and the signature variety of the Midwest, is deficient in lysine. But in the 1990s, researchers successfully bred a gene variant known as opaque-2 into dent corn. In lowering the production of normally dominant prolamin proteins, opaque-2 allowed for a rise in non-prolamins: those containing lysine and another essential amino acid, tryptophan. The resulting variety — Quality-Protein Maize, or QPM — has since helped combat malnutrition in many developing countries.

    With the backing of Conagra Foods, Holding decided to try the same in popcorn.

    “It turns out that that’s really difficult to do,” said Holding, professor and associate department head in the Department of Agronomy and Horticulture.

    The problem was at once simple and complex: Popcorn containing opaque-2 wouldn’t pop. And that problem stemmed from what’s in its name: Opaque-2 tends to turn popcorn’s normally hard, glassy kernels into softer, chalkier forms resistant to popping.

    Agronomists had previously managed to breed the undesirable softness trait out of the QPM dent corn, which was otherwise more susceptible to pests and harvesting damage. But they did so mostly without knowing which genes helped restore the kernels’ glassy consistency.

    Holding had devoted considerable time to identifying swaths of the corn genome responsible for restoring that glassiness. So he set out to cross-breed multiple generations of the QPM dent corn with popcorn varieties selected to contain the restorative genes.

    The outcome? High-lysine Quality Protein Popcorn (QPP) that pops as well as the original variety.

    “When this project started, I wasn’t sure we could achieve that, given that people hadn’t been very successful in transferring beneficial traits from dent corn to popcorn in the past,” Holding said. “We’re the first to take the dent QPM variety and successfully convert that into popcorn, achieving high lysine and maintaining popping.

    “This is a product that lends itself to organic production and can be marketed as a novel popcorn variety, as consumers are paying more attention to their foods’ nutritional value. For popcorn breeding in general, this also shows the potential for mining other traits from dent corn into popcorn to improve the crop’s agronomic performance.”

    Other advancements include blind taste testing — many of the Nebraska QPP hybrids outperformed the non-QPP lines in terms of taste and texture — and working with the Nebraska Food for Health Center to show positive prebiotic impacts of the popcorn.

    “What we’ve developed here is a complete protein snack that can be marketed as a superfood due to its positive prebiotic qualities,” Holding said. “And it isn’t just a snack food. It is also quite nutritious and could be beneficial as a dietary supplement in developing countries where protein is needed.

    “This work has truly been much more successful than we expected.”
