“Sex and death are the only things that can interest a serious mind”*…

As Greg Woolf observed, “The Epic of Gilgamesh is one of the earliest examples of what is sometimes termed a “Mirror of Princes,” a book that illustrates the conduct of both bad and good rulers, and makes clear the difference between them.”

Nicolas Liney reviews a new verse translation of the 4,000-year-old text by Simon Armitage and considers its remarkable power, its extraordinary history, and its profound relevance to our moment…

There are two stories of Gilgamesh, the ancient Mesopotamian epic written in the second millennium BCE. First, there’s the story of Gilgamesh himself, the semidivine king of Uruk. He is 11 cubits tall and four cubits from nipple to nipple (roughly 16 by six feet). He is hyperactive and priapic. He is not a good ruler. The gods create the wild Enkidu out of clay to keep him in check. The pair clash mightily, and then become inseparable. Restless and hungry for glory, they journey to the Forest of Cedar to defeat the monster Humbaba. Then they slay the Bull of Heaven sent by Ishtar, the god of sex and war whose advances Gilgamesh rejects. The gods deem that Enkidu must die, and so he does, slowly and unheroically. Gilgamesh watches over Enkidu’s body until a maggot falls from his nostril, a fantastically intense image that drives home death’s finality.

At this point, the register of the poem shifts, and Gilgamesh’s triumphs are replaced by sorrow and an overwhelming awareness of his own mortality. Alone and anguished, he journeys to the underworld to visit Uta-napishti, the immortalized survivor of a cataclysmic flood, intent on unlocking the secret to eternal life. Inevitably, he is disappointed and returns to Uruk. Gilgamesh is an epic about power, about self-knowledge, about passionate companionship and the unquenchable pain of its loss. Fundamentally, it is an epic about death. Rilke labeled it “das Epos der Todesfurcht”—the epic of the fear of death—and this is what gave it its vital appeal: “It concerns me,” he confessed. “Thousands of years later death is no less bewildering to humankind,” the poet Simon Armitage says in the introduction to his new translation of the epic; “there is no more relatable subject.”

The second story of Gilgamesh is about the text itself, one of the world’s oldest surviving long-form poems. Like Homeric epic, its roots are most likely oral, and questions of authorship are futile. The earliest version was a Sumerian cycle of five poems from around 2100 BCE, probably part of a larger group of stories about the heroic dynasty of Uruk. Sumerian eventually died out, and the five episodes were replaced by one unified version in Akkadian. This was recorded in cuneiform script, often carved in clay tablets, and spread throughout Mesopotamia and the Levant. Sometime between 1300 and 1000 CE, a man called Sin-leqi-unninni created a heavily revised edition organized into 11 “tablets”—referred to now as the Standard Version—which was copied widely and included in the great library of Ashurbanipal, the Assyrian king, built in Nineveh in the seventh century.

And then … silence. By the new millennium, Akkadian was a defunct language, and Uruk and Nineveh were in ruins. As far as we know, Gilgamesh was not translated into other writing systems, so when cuneiform fell out of use, the epic seemed to go with it. For centuries it slept, until the Library of Ashurbanipal was discovered by Austen Henry Layard and Hormuzd Rassam in 1850, and what documents could be recovered were transported to the British Museum. Cuneiform was eventually deciphered, and in 1872, George Smith, an assistant curator working on the archive, came across a fragment of the epic describing a great flood—similar to the one in the Book of Genesis,but in a work significantly older than the Bible. This was too much for Smith, who began stripping his clothes off in excitement: “I am the first man to read that after more than two thousand years of oblivion.”

Critics like to say that Gilgamesh is both incredibly old and refreshingly young. Its sheer age staggers—for comparison, just try to imagine a current novel being rediscovered in the year 5120 CE. As a quasi-historical figure, Gilgamesh was considered by Babylonians to be even older: the Sumerian King List,a chronographic record,hyperbolically places his reign in 7800 BCE. Within the world of the epic itself, time reaches back further still: when Gilgamesh meets Uta-napishti, the Noah-type figure who survived the flood long before Gilgamesh, even he can speak of an “ancient city,” Shuruppak, on the banks of the Euphrates. The epic constantly forces us into these dizzying loops of deep time, forces us both to drastically exceed the limits of our brief lifespan and to be persistently reminded of them.

But Gilgamesh’s comparatively recent reentry into the modern imagination makes it feel fresh, not overburdened by centuries of interpretation and adaptation, like Homer or Virgil, and firmly outside Western literary traditions. There is no first looking into Chapman’s Gilgamesh.This can be dangerous for translators and adapters: there’s an urge to treat the epic like a blank canvas, to make it say something relevant to contemporary concerns, which can strip it of its strangeness and also cut it loose from its Iraqi heritage. But the subject matter of Gilgamesh also seems undeniably contemporary: how could a story about ecological destruction, poor leaders, and misogynist alphas not concern us here and now?…

Eminently worth reading in full. A classic which has survived, against all odds, and what it offers us today: “The Epic of the Fear of Death” from @lareviewofbooks.bsky.social.

As we reach back, we might recall that it was on this date in 2004 that the discovery of what was (and is) believed to be the world’s oldest seat of learning (dating from 295 BCE), the Library of Alexandria, was announced by Zahi Hawass, president of Egypt’s Supreme Council of Antiquities during a conference at the University of California. A Polish-Egyptian team had uncovered 13 lecture halls featuring an elevated podium for the lecturer. Such a complex of lecture halls had never before been found on any Mediterranean Greco-Roman site. Alexandria may be regarded as the birthplace of western science, where Euclid discovered the rules of geometry, Eratosthenes measured the diameter of the Earth and Ptolemy wrote the Almagest, the most influential scientific book about the nature of the Universe for 1,500 years.

Największa mapa Wszechświata gotowa. Właśnie zaczyna się trzęsienie ziemi w świecie fizyki

Instrument DESI (Dark Energy Spectroscopic Instrument) oficjalnie zakończył swój pierwszy, zaplanowany na pięć lat cykl pomiarowy.

W tym czasie skatalogował 47 milionów galaktyk i 20 milionów gwiazd, obejmując 11 miliardów lat historii kosmosu i tworząc największą w dziejach trójwymiarową mapę Wszechświata. Choć sam proces głównego skanowania nieba dobiegł końca, dla astrofizyków prawdziwa praca i wielkie pytania dopiero się zaczynają.

Nowa próba rozwikłania paradoksu Hawkinga. Czarne dziury mogą ukrywać informacje w dodatkowych wymiarach

Koniec misji obserwacyjnej w astronomii rzadko oznacza koniec projektu. Jak tłumaczy prof. Will Percival, jeden z szefów projektu DESI: „Kiedy dysponujesz takim przeglądem galaktyk, stoisz przed prawdziwą kopalnią złota. W rozmieszczeniu tych obiektów zakodowana jest potężna ilość fizyki”. Przetwarzanie i naukowa analiza zebranych danych potrwa od kilku miesięcy do nawet kilku lat, a stawka jest gigantyczna – chodzi o odpowiedź na pytanie, jak ewoluuje Wszechświat i jak może wyglądać jego koniec.

Problem ze stałą Einsteina

Współczesna kosmologia opiera się na tzw. stałej kosmologicznej (lambda), wprowadzonej jeszcze przez Alberta Einsteina. To ona matematycznie opisuje ciemną energię – tajemniczą siłę, która odpowiada za to, że Wszechświat rozszerza się coraz szybciej. Standardowy model zakłada, że gęstość tej energii jest absolutnie stała i niezmienna w czasie.

Problem w tym, że dane z instrumentu DESI zdają się temu przeczyć. Już analiza wyników z pierwszych trzech lat działania teleskopu zasugerowała, że ciemna energia może wcale nie być stała, lecz ewoluować i zmieniać się w czasie. „Gdyby to się ostatecznie potwierdziło, mówimy o potężnym odkryciu, które wywróciłoby do góry nogami standardowy model kosmologii” – zauważa astrofizyk Kev Abazajian z Uniwersytetu Kalifornijskiego w Irvine.

Dla fizyków teoretycznych to sytuacja niezwykle problematyczna. Wbudowanie lambdy w stuletni gmach teoretycznej fizyki było tak trudne, że dziś nikt nie wie, jak i gdzie zacząć go przebudowywać w przypadku udowodnienia błędu. Naukowcy mówią wprost o swego rodzaju przeciąganiu liny między rzeczywistym zachowaniem Wszechświata a ugruntowanymi od dekad prawami fizyki.

Co dalej?

Aby ostatecznie potwierdzić anomalię ciemnej energii, badacze muszą mieć absolutną pewność co do marginesu błędu w swoich pomiarach. Obecnie trwa przygotowywanie finalnej, „czystej” paczki danych z pełnych pięciu lat działania DESI (proces ten zajmie jeszcze od dwóch do czterech miesięcy). Równolegle przygotowywane są kolejne publikacje naukowe oparte na dotychczasowych informacjach.

Jednocześnie fizycy z niecierpliwością czekają na wyniki z innego, niezależnego źródła – europejskiego teleskopu kosmicznego Euclid, którego pierwsze, ogromne zbiory danych mają zostać opublikowane w październiku tego roku. Jeśli oba, tak różniące się od siebie systemy obserwacyjne, wykażą dokładnie takie same, ewolucyjne cechy ciemnej energii, świat nauki czeka wkrótce potężne trzęsienie ziemi i konieczność napisania podręczników na nowo.

Euclid Space Warps – help the hunt for galaxy-galaxy lenses!

I’m sharing the text of a press release from Euclid here to encourage readers to join in this new Zooniverse project.

–o–

In brief

With the launch of Space Warps, a new citizen science project on the Zooniverse platform, you can now join in the search to find rare and elusive strong gravitational lenses in never-before-seen images captured by the European Space Agency’s Euclid space telescope. The project aims at shining a light on dark matter in galaxies and providing clues about mysterious dark energy.

In-depth

Warps in spacetime do not only show up in science fiction movies like Interstellar. In real life, we can see the warping effect that gravity has on spacetime in the form of gravitational lensing.

The enormous gravity of a massive object – such as a galaxy or cluster of galaxies – distorts the shape of spacetime and can bend the light rays coming from a distant galaxy behind. By warping spacetime, the foreground galaxy acts like a magnifying glass.

Light from the background object that would be obscured doesn’t travel in a straight line anymore. Instead, it curves around the intervening mass, often producing multiple images, stretched arcs, or even a complete ring known as ‘Einstein ring’, like the one recently discovered by Euclid.

Strong gravitational lenses offer a striking demonstration of Einstein’s theory of general relativity, showing that matter in the Universe can act as a natural telescope, bringing distant objects into sight.

ESA’s Euclid telescope is revolutionising the studies of strong gravitational lensing by providing very sensitive imaging over large swaths of the sky in unprecedented detail. This is exactly what is needed to identify rare gravitational lenses.

In March 2025, 500 galaxy-galaxy strong lenses were found nestled in just the first 0.04% of Euclid data, most of them previously unknown. This pioneering catalogue was created thanks to the combined effort from citizen scientists, artificial intelligence (AI) and researchers.

Early glimpse of new Euclid images

As Euclid continues its survey, sending around 100 GB of data back to Earth every day, ESA and the Euclid Consortium once again need help from citizen scientists to identify strong gravitational lenses in a large data set.

For this, the Space Warps team has launched a citizen science project based on new Euclid images, which will be part of the future Euclid Data Release 1. While this data is not public yet, by participating in this new citizen science project you can get an early glimpse of these new images of galaxies captured by the telescope.

For this project, you will be inspecting new high quality imaging data from Euclid in which many previously unknown strong lenses are hiding. About three hundred thousand images pre-selected by AI algorithms will be shown, which are fine-tuned with the results from the initial citizen-science Euclid strong lens search. These are the highest ranked candidates from a whopping 72 million galaxies from DR1 that were classified by the AI algorithms. Scientists expect that this exquisite high-quality data will reveal more than 10 000 new lenses.

What can we learn from strong lenses

The Euclid mission explores how the Universe has expanded and how its structure has changed through cosmic history using mainly two methods: weak lensing and baryonic acoustic oscillations. From this, scientists can learn more about the role of gravity and the nature of dark matter and dark energy.

Strong gravitational lenses can also provide insights into these central questions. For example, strong lensing features can ‘weigh’ individual galaxies and clusters of galaxies. This reveals the total matter (whether dark or light) and traces the distribution of dark matter. By studying strong lenses across cosmic time, scientists can trace the expansion of the Universe and its apparent acceleration. This will provide additional insight into the role of dark energy.

“We’ve already seen the success of combining AI with visual inspection by citizen volunteers and scientists on Space Warps, efficiently finding hundreds of high‑probability lens candidates in an initial small Euclid search in 2024”, explains Aprajita Verma, Space Warps’ co-founder and project lead at the University of Oxford, UK.
“In this brand new DR1 data, 30 times larger than the initial search and together with our improved AI algorithms, we are expecting to find more than 10 000 high quality lens candidates. This is more than four times the number of lenses than we have been able to find since the first gravitational lens was discovered nearly 50 years ago.”

This step-change is possible thanks to Euclid. The mission can map large areas of the sky with unique sharpness, an ideal combination for finding rare objects like strong gravitational lenses.

“We can’t wait to see what we will find within this unprecedented dataset. Join us on Space Warps to take part in this exciting search!” concludes Aprajita.

About Euclid
Euclid was launched in July 2023 and started its routine science observations on 14 February 2024. The goal of the mission is to reveal the hidden influence of dark matter and dark energy on the visible Universe. Over a period of six years, Euclid will observe the shapes, distances and motions of billions of galaxies out to 10 billion light-years.

Euclid is a European mission, built and operated by ESA, with contributions from NASA. The Euclid Consortium – consisting of more than 2000 scientist from 300 institutes in 15 European countries, the USA, Canada, and Japan – is responsible for providing the scientific instruments and scientific data analysis. ESA selected Thales Alenia Space as prime contractor for the construction of the satellite and its service module, with Airbus Defence and Space chosen to develop the payload module, including the telescope. NASA provided the detectors of the Near-Infrared Spectrometer and Photometer, NISP. Euclid is a medium-class mission in ESA’s Cosmic Vision Programme.
