After centuries of study and several attempts to understand and recreate the colour-changing effect, a team from the University of Sheffield—an area instrumental to the Industrial Revolution, many technologies emerging from there including large scale stainless steel and commercial glass manufacture—have rediscovered the sixteen hundred year old methods that went into dichromatic the Lycurgus Cup (see previously here and here).
The caged-chalice (diatretum) was made in Alexandria in the fourth-century of unknown provenance before the 1800s depicts a scene of the mythological Thracian king Lycurgus (Tamer of Wolves) who banned the cult of Dionysus (Bacchus to the Romans) in his home territory and punished the followers of the god of wine, and in the iconography on the cup, Ambrosia, Dionysus’ human nursemaid, is shown acting in self-defence, transformed into a powerful vine as she is being pursued by the enraged despot, whereupon entangling him, rending his wardrobe (a act called sparagmos (ฯฯฮฑฯฮฑฮณฮผฯฯ) and strangling him to death.
Embedded flakes of silver and gold (molten nano-crystals forming a lattice work in the glass invisible to the naked eye) shift the absorption and scattering of photons depending on whether the artefact is backlit or viewed in ambient light. Our favourite part of the interview was how one of the scientists imagined how Roman craftspeople would be bemused and incredulous on the effort and experimentation that went into recreating the effect, “‘Why does she not know how to make this?’” The new cup, a local glass artist commissioned to make it, will be unveiled to the public next month at the university.

house elf (13. 702)
We‘ve heard of several road construction projects diverted or completely derailed in Iceland to avoid encroaching on the dwellings of supernatural beings according to local lore. We learn, however—and not for the first time, fans of the Harry Potter franchise have successfully petitioned to reroute a multimillion pound energy project linking County Wexford in the Republic of Ireland with a pebbly beach in Pembrokeshire, Wales, which would have cut through the shrine to the memory of the fictional familiar Dobby.
The submarine copper cables connecting the Republic of Ireland to the UK national grid, following a rather massive outcry, was shifted to avoid the memorial—though in the process could possibly have damaged an archaeological site, an actual Bronze Age tomb with grave goods not fully excavated and conserved.

casco de leiro (13. 327)
With hammered decorations and repeating repouseรฉ work, the register of patterns similar to other headgear of the era, like the hats of Schifferstadt, the so called Helmet of Leiro is a ritual golden cap dating to the Late Bronze Age (circa 1000 BC) was discovered by chance on this day in 1976 on a rocky point above the beach at the comarca (a subdivision, like a county, used in Galicia) of O Ribeiro by fisherman called Josรฉ Vicente Somoza.
The view from the outcropping is a commanding one of the bay and would have made an inspiring location for rites as well as a reference point for navigation, the waterways receding landward from the estuary the optimal route to the nearby site of Santiago de Compostela and according to legend the same path chosen by St James. Retrieving what he appeared to be a crude earthenware bowl (artefact is suspected to have a dual use as a basin), the outer layer broke away upon handling it, revealing a gold object, which the discoverer immediately reported to local archaeological authorities.

Recent excavations of a Romano-Briton grave of a young woman in the northern Cotswolds have uncovered an item unique in the archaeological record with no comparable artefact yet found in this delicate bone box with sliding lid and decorations similar to the circle and dot pattern of Roman dice. Finely crafted from the femur of a deer, researchers conjecture the petite object might have been a compact for makeup or a precious ointment but who knows? This nameless woman could have been a skilled assassin and kept her poisons in this precious keepsake buried with her. Learn more from The History Blog at the link up top.

ys (13. 014)
Via Strange Company, we learn that a substantial undersea wall discovered by marine archeologists off the coast of the รle de Sein near Finstรจre in Bretagne—which has its own lore according to classical sources and historians,
including Strabo, writing that men were forbidden on the island sacred to the Gallizenae, a caste of Druid priestesses whom could control the wind and foretell the future, but also accused of luring sailors to the their deaths, bashed on the rocky cliffs. Researchers believe that the seven millennia old wall may have been a fish-trap to harvest between tides that became submerged or possibly a protective dyke (though unlikely that humans could have forward-planning) and abandoned with sea-level rise, and pre-dating the ensemble of menhirs of the area, may be behind the legend of the sunken kingdom of Ys.

little big town (12. 863)
Though a bit of an inconvenience to have to go into the next bigger Marktstadt outside of the village for any kind of shopping, it always pays off in spades, by sheer dint of concentration of attractions there and spots for a nice wander, even on a foggy day:
Ostheim vor der Rhรถn has the Altstadt lining the main road with several mills, manors, breweries and bottlers and fortified church, an organ museum and manufacturer and a castle ruin with tower above—plus a lot more. We had visited the ensemble of Celtic hill graves (Hรผgelgraben) right down the road from the grocery store several times but hadn’t before now hiked up to the top which hosts a model aircraft runway—opposite the higher summit that has a glider Flรผgplatz—see also. The grove of maples at the top of the hill is known as the Sporkhรถhe and has a monument dedicated to silk merchant Kaspar Friedrich Sporck. A native of Ostheim and having learned the art of passementerie—elaborate braidwork trimmings for clothing and furnishings—from his father, made a sizeable fortune in Rouen. Sporck married his business partner Marie Catherine Leprince and remained in France, although visiting his hometown nearly every year, always bringing remittances for support of the poor. The couple passing away at an advanced age in the early 1890s, they established a philanthropic foundation (Stiftung) for the town, underwriting an elementary school, the general welfare of the town and a hospital, then hosted in the Gothic Schloร Hanstein, presently the organ museum from above.Sunday, 2 November 2025
rock on gold dust woman (12. 844)
Missing this gift exchange during the last leg of Trump’s Asia in the chaos of last week—which netted no concrete trade deals other than a tepid tariff rapprochement with China—it seems in poor taste at first blush for South Korean president Lee Jae Myung to have presented the US president with a replica of an ancient gold crown, particularly right after the No Kings demonstrations, and bestowed on him the Grand Order of the Mugunghwa (Pink Hibiscus) and it’s of course pandering to his doltish vanities.
A little low-effort research reveals, however, a possibly deeper meaning that’s half again cleverer than the copy of the birth certificate that Germany gave Trump of his ancestor who fled to avoid the draft and was subsequently stripped of his citizenship. Dating from the Silla dynasty (see previously) and designated among Korea’s National Treasures these delicate gold crowns, with the tensile strength of a tin-foil hat, which were discovered during an excavation of a royal tomb in the old capital city of Gyeongjuwere likely crafted as funerary wares and not to be worn by the living, due to their inherent flimsiness and impractical design, with this lavish headdress a burial good. That’s some apt diplomacy (see also), especially after the US deported all those South Korean workers.

thirteenth pharaoh of the eighteenth dynasty (12. 832)
After a pause of more than three year after the discovery of the undisturbed burial chamber, the mummified remains of Tutankhamun were discovered on this day in 1925 by Egyptologist Howard Carter and his team.
Over three thousand years after his death, the king is notably the only mummy yet found completely intact and with no sign of tampering and despite the famous find and iconic nature of his gold and lapis lazuli death mask, very little is known about the individual’s circumstances or cause of death, other than a reign of about a decade dedicated to undoing the much the cultural and religious reforms enacted by his predecessor and father Akhenaten and expiring only as a young adult, hence referred to a the boy-king. Laid to rest in a series of nested coffins which we carefully opened to reveal the golden sarcophagus—the headdress crafted to give him the likeness of the god Osiris. Inlaid with faience and precious stones, the back of the mask is inscribed with a chapter from the Book of the Dead, a collection of creation and resurrection texts, spells and incantations used in funerary rituals. Studied forensically for nearly a year, the body was indelicately separated from the gold coffin and reinterred within one of the larger ones and stays in repose in Luxor in the Valley of the Kings. Although contributing much to public awareness of the field of archaeology, Tutankhamun’s treasures and alleged curse—published and propaganda in the following decades, turned out to be more captivating than his mortal remains.
