erlebnis bergwerk (10. 073)

Decommissioned since 1993 but revitalised since as a living museum and working mine and venue, I had a chance to visit with H’s father the salt and potash (Kalisalz, used as an important agricultural fertiliser) extraction operation near the village of Merkers on the Werra river not far from Bad Salzungen.  

 Aside from the long history of mining and a comprehensive lesson on the enterprise and geology that bores under the Rhön mountains, the location is also the hiding spot for hundreds of tonnes of gold, silver and paper currency (amounting to around eighty percent of the holdings of the Reichsbank at the end of the war) and many priceless works of art looted by the Nazis, discovered per chance by the advancing United States army (tipped off by slave labour transporting treasures to the mine) who then worked quickly to clear it out of Soviet occupied territory before the borders were demarcated.

After being lowered in safety gear—like actual miners beginning their shift—in a hoisting cage that descended into the dark, and driven in flatbed transports from five to eight hundred metres below the surface through a network of tunnels that covers an area the size of Munich. 

Though the vehicles were only taking the dips, curves and ascents at under twenty kilometres an hour, the darkness, wind and narrowness of the shaft made it seem much faster, like a roller coaster ride stretched out for some two hours, with intermissions, lastly in the above Goldraum, a pair of excavated former bunkers that now serve as a machine exhibit, theatre and a concert hall with uncommonly good acoustics and unique crystal grotto with accompanying bar for refreshments—the deepest in the world.  

It was definitely worth the visit and would drag H along next time.

On this day 1839 following assurances of a lifetime’s pension for himself and business partner Nicéphore Niépce and a seat on the National Academy of Design, the government of France published the complete technical details of the daguerreotype process—previously withheld over fears of others counterfeiting the process or stealing credit for the research and experimentation of set building, background painter and inventor of the diorama Louis-Jacques-Mandé Daguerre—gifting it “free to the world.”

Via Waxy, we learn that chindōgu engineer and friend Simone Giertz has created a music box that produces its melodies from popping bubble-wrap, configured specifically to play the Moog-standard “Popcorn” by the group Hot Butter. The dedication to the project and process is admirable and quite ingenious.

On this day in 1922, engineering and hang-gliding pioneer Arthur Martens—lieutenant and front-line pilot with the Red Baron’s fighter squadron—participating in the Rhöner Gliding Competition (Segelflugwettbewerb) took to the air, launched from a rubber rope in a glider of his own design from the Hannoversche Waggonfabrik (HaWa—see also), on the Pferdskopf slope of the Wasserkuppe, the highest mountain in the range, and set three records for endurance, altitude and distance in an unpowered craft. Flying for over an hour, Martens flew a distance of just under nine kilometers circumnavigating the Wasserkuppe ten times, taking advantage of updrafts to glide in a figure-eight, demonstrating for the first time a technique that’s employed by all pilots a century later.

bona stabularia (10. 069)

Referred to by some historians as a “goodly stablemaid” and likely from humble roots in Bithynia (Anatolia)—though other counterclaimants, as with Charlemagne or any number of the artefacts she collected vying for authenticity, are out there including Augusta Treverorum, Mesopotamia, Palestine, the Pyrenees and Camulodnum (Colchester—a princess of the legendary Ole King Cole)—widowed wife and empress dowager of Constantius, relic-hunter and mother to Constantine I, Helen (Flavia Iulia Helena) is fêted in the Roman Catholic Rite on this day as patron protector of the Holy Places and archaeologist, converts and divorcees. Helen was assigned this last benefaction as Constantius divorced her when Constantine was a teenager to take a wife of higher status, Theodora, and the two of them were exiled to the court of Diocletian in Dalmatia. After his father died in battle fighting against the Picts at Eboracum (York) and Constantine was proclaimed emperor, Helen returned to the imperial court and after her son’s consequential victory at the Battle of the Milvian Bridge and subsequent conversion to Christianity was appointed Augusta Imperatrix with unfettered access to the treasury and given the special assignment of collecting objects of Christian veneration, including the True Cross—the place of discovery now hosting the Church of the Holy Sepulchre, and the Holy Tunic.

i let the music speak (10. 067)

Released as a record album at the end of November 1981 and the groups last studio album for four decades until their 2021 reunion, ABBA’s The Visitors was among the first to be digitally mixed and recorded and on this day in 1982 became among the first to be pressed and issued in CD format (Polygram Records also put out a disk of Chopin waltzes and Phillips would be releasing a tranche of some fifty artists including Billy Joel available in stores in the autumn). Despite personal conflicts that strained their professional relationship and musical partnership, this final collaboration was a success, cathartic and critically well received. Still getting accustomed to the new technology, the sound engineers thought the recording to be too clean and missed notes and beats would be harder to overlook.

transatlantic (10. 066)

After a benedictory message from the directors of the Atlantic Telegraph Company in Great Britain to their US counterparts, “Europe and America are united by telegraph. Glory to God in the highest; on Earth peace, good will towards men,” Queen Victoria and president James Buchanan—from his summer residence in Bedford Springs, Pennsylvania—exchanged congratulatory greetings on this day in 1858, with the former observing that the submarine cable would “provide an additional link between the nations whose friendship is founded on their common interest and reciprocal esteem” to the latter’s more effluvious response “It is a triumph more glorious, because far more useful to mankind, than was ever won by conqueror on the field of battle. May the Atlantic telegraph, under the blessing of Heaven, prove to be a bond of perpetual peace and friendship between the kindred nations, and an instrument destined by Divine Providence to diffuse religion, civilization, liberty, and law throughout the world.” These inaugural overseas telegrams were quite laborious to encode and decode (see also), with the queen’s shorter missive taking sixteen hours to transmit and reception was quite poor but there was no dissuading the public’s enthusiasm—commercially, however, investors balked at the outcome considering the expense of the expedition to lay the cable and when the original linkage broke three weeks later—probably an inevitability due to faulty materials and manufacturing—confidence was sunk and delayed efforts to replace it. The termina (see previously), the most easterly and westerly points on land, were in Sunnyside, Bull Arms Bay, on the Avalon Peninsula in Newfoundland and Telegraph Field on Valentia Island, County Kerry.
