Interested in the ways brains process visual information and the influence of context and frame of reference, psychologist Jules Beuchet first described his eponymous chair illusion in the mid twentieth century, and while popular for museum installations and retaining the effect in photographs unlike some others (see also here and here), we learn that the compelling dissonance, accidentally exemplified by this image of the giant Bidens with the tiny Carters without set up—courtesy of Futility Closet—we discover a new, more portable technique for disabusing this trick, staged easier with a tripod, a miniature frame and piece of upholstery, requiring much less space and focal length to achieve the result.

tal und berg, time and temperature (12. 688)
Running some errands back in the Geratal region, we took a stroll through the village above the valley called Geraberg, higher up on the slope of the Arlesberg on the northern edge of the Thรผringer Wald. Though first mentioned in a deed of gift to the Henneberg knights for its vineyards in the eleventh century, the area was more famous of its traditions of mining and forestry, fuelling the smelting of iron ore. The cadet industries of glass-making and porcelain manufacturer developed in the nineteenth century and taking advantage of one by-product of mining operations, mercury, Geraberg became a centre of technical expertise for the making of clinical thermometers (that’s one in the main traffic circle) and other glass medical instruments, beginning in 1873 and lasting until 1990, employing some two-thousand individuals. There was also a museum dedicated to the village’s association with the device, along with the broader technological advancements from contact to digital thermometers and thermostats, closed Mondays but looks worth checking out on a return trip.

the stars at night are big and bright (12. 598)
Just ahead of the August fortieth anniversary of the release of the movie, the Alamo has acquired the iconic, custom Schwinn DX Cruiser that appeared on screen in Pee-wee’s Big Adventure. Directed by Tim Burton (his first time in that role), scored by Danny Elfman (their first collaboration) and cowritten by Paul Reubens and Phil Hartman, Herman travels cross country in search of his stolen bicycle—a plot comparable to the 1948 Ladri di biciclette, hitchhiking to Texas after being told by a fake psychic that his beloved bike is in the basement of the San Antonio mission. The film prop will go on display in the visitors’ centre and museum of the Alamo, in the sublevel that famously did not exist at the time of the shooting, a space below the gift shop also used as a reception hall. This accession was undertaken by a private trust that maintains the monument’s collections, an acquisition unrelated to Texas’ attempted gallery heist of the Space Shuttle Discovery from the Smithsonian.

militรคrgeschichtliches denkmal (12. 592)
After doing the weekend shopping in Mellrichstadt (previously), we stopped in the in the Hainberg Arreal on the edge of town for a walk on the groups of the mothballed border garrison of the Cold War. By the old security gate there was a collection of the kind of tanks from the motor pool and the headquarters building preserved in its original condition, furnished as it was during its forty-four year history as home base to the 352nd Panzer Grenadier Battalion of the West German Bundeswehr.
The museum and documentation centre was closed when we visited but I got immediate feelings of nostalgia for the former US army barracks in Wรผrzburg, Kitzigen, Schweinfurt, Giebelstadt, etc, etc with the same general layout and style of the few representative structures—which of course were German-built and occupied by the Allies at the end of World War II—but learned it contains the command room with access to the bunker and fallout shelter (see also, worth going back for) as well as an arms room and information on the unit’s patrols and foreign missions up to Afghanistan in 2006 after which the brigade was disbanded and the base closed.

apocalypse hier et demain (12. 515)
Realising the resonance of revelation seems less abstract now than in more peaceful and sanguine times, a special exhibition put together by the Bibliothรจque nationale de France of images and interpretations of the End of Days spanning from medieval manuscripts to nineteenth and twentieth century depictions, like the pictured rendition from chapter twenty of the enchained dragon locked away for a millennium from Symbolist draughtsman Odilon Redon, curated in a fashion that is meant to make visitors reflect on the choices that brought us to this eschatological inflection point and the spiritual housekeeping that might prove a measure redeeming rather than a fatalistic preoccupation with the end of the world. From the Koinฤ Greek incipit แผฯฮฟฮบฮฌฮปฯ
ฯฮนฯ for unveiling, the prophetic text of John of Patmos, a series of visions recorded in the Book of Revelations in a grotto on the small Aegean volcanic island received by one of Jesus’ apostles banished like many others of this new cult seen as a political subversive to a penal colony and sentenced to hard labour. After a missive to the Seven Churches of Asia—“he who has an ear, let him listen to what the Holy Spirit say”—relating his instructions, John commits his fantastic and symbolic disclosures in florid detail with iconic and inscrutable figures like the Son of Man among seven lampstands, the Whore of Babylon, the Beast with Seven Heads, the Four Horsemen, the Woman Clothed with the Sun. The numbers seven and four in this context refer respectively the perfection of the hereafter and the imperfection of the present world according to ancient numerological traditions. Much more on the showing from Hyperallergic at the link above.

hubertusburg (12. 400)
For Easter Sunday, we returned to Wermsdorf and the Rococo palace built at the behest of elector and Polish king Augustus the Strong, the hunting lodge (see previously here and here), known as the Saxon Versailles whose expansive grounds are also reminiscent of Schwetzingen in the Neckartal.
After the war, the palace was used as a hospital and in 2006, refurbished as specialist clinic with a psychotherapy, neurology and paediatric department and also contains the state archives and a museum hosting revolving exhibits, currently for local son and inmate Karl Hans Joachim Janke, prodigious modeller and illustrator of fantastic aerospace concepts which blur the line between engineering and art brut (see previously).
Diagnosed with schizophrenia after being discharged from the military, Janke was afforded a meagre pension to operate a workshop crafting toy airplanes but due to wartime rationing for cardboard and other supplies had to discontinue his hobby, remanded to psychiatric care at Hubertusberg after a less than patriotic outburst for the lack of resources for even the smallest of distractions for children. At hospital, Janke never lacked for material and his designs and correspondence were rediscovered in an attic of the castle in 2000, including over three-thousand drawings for innovation aircraft, concepts for harnessing nuclear energy and the Earth’s magnetic field for propulsion.

la a note to follow doge (12. 346)
Releasing yet another executive order aimed at whitewashing the country’s past, Trump’s “Restoring Truth and Sanity to American History” is aimed at museums and other cultural institutions to remedy what MAGA regards a concerted effort by the radical left of revisionism geared to deepen societal divides and promote national shame. The Smithsonian has been politicised and weaponised, ordered to halt exhibits and articles featuring “race-centred ideology,” calling examination of marginalisation effectively anti-American, with vice president Vance deputised with the power to review all publications, projects and presentations to ensure compliance. One wonders when Americans might have their fill of liberty—it seems like a line has already been crossed yet new horrors come. The order also implies that like with earlier dictates that there are only two genders, that race is a biological reality, rather than a social construct playing into the pseudoscience that justifies eugenics and segregation and directs the administration’s secretary of the interior to begin reinstalling and rededicating Confederate and racist statues and monuments toppled or taken down in the course of the Black Lives Matter movement. Attempts to erase the past follow the wholesale assault on present postures diversity, inclusion, equity and access is a regression of decades of struggle against hate and oppression but unlikely to determine the future shape of society.

hr 1968 (12. 305)
Though hard to forecast what might have been the better path through an undesirable binary, and mostly cleaving to party lines, an early procedural vote against cloture and ultimately advancing of a continuing resolution through the senate to avoid a US government shutdown at midnight seems to have been a grave political miscalculation with Democrats squandering the only leverage they had to slow or derail Trump’s dismantling of the federal bureaucracy. In response to Musk commenting that closing down the government might be a preferable course of action for the DOGE agenda, senate minority leader Chuck Schumer reversed his stance on the spending bill that keeps government funded through the end of the fiscal year and along with nine other Democrats, voted with Republicans for the passage, reaching the sixty votes needed to avoid a filibuster—earning praise from Trump for his decision and highlighting deep divisions within the party. If the GOP had wanted the government to shutdown, they wouldn’t have advanced the budget in the first place, which until it passed the first hurdle of the house of representatives, Democrats were united against it. The CR is essentially a sequestration, maintaining funding levels but removing line item allocations and collapsing appropriations into larger pots of money, further abrogating the role of congress and allowing the executive branch to move funds, legally, as it sees fit. Unabated with his assault on the republic, Trump issued more executive orders while roll-call was happening on the senate floor, rescinding the federal minimum wage of fifteen dollars per hour, the mandate for agencies to share data on emergent public health threats as well as order the closure of the parent agency that operates Voice of America and Radio Free Europe and smaller offices that handle labour disputes, the council on homelessness, developing minority-owned businesses and the institute of museum and library services—agency heads given seven days to justify their existence and prove that their work is statutorily required.

england’s home of mystery (12. 154)
Sadly demolished in 1905 to make way for offices and flats, we enjoyed this appreciation of the Egyptian Hall in Piccadilly, originally commissioned by antiquarian and naturalist William Bullock as a museum to house his collection of curiosities acquired by Captain Cook’s exploration (see also) of the South Seas and built in 1812 in the revival architecture style popularised (see also) by reports of Napoleon’s exploits and Admiral Nelson’s defeat of the French navy on the Nile, which after disposing of his ethnographic and natural history collection, transformed the space into a public exhibition hall, with rotating collections including Napoleon’s carriage captured as a war trophy at Waterloo, Egyptian artefacts and The Raft of Medusa. By the end of the nineteenth century, the hall became a venue for magical acts and spiritualism demonstrations, chiefly staged by the duo of Maskelyne and Cooke with a rather remarkable run of thirty-one years—the former, John Nevil, stage magician, card shark, professional sceptic (wanting to expose fraudsters and charlatans) and inventor of a typewriter of proportional character width (kerning was apparently all over the place and probably would have driven me to distraction) and the pay-toilet, hence the euphemism, “spend a penny.” Much more from Feuilleton at the link above including a gallery of show posters.

We’ve received a happy status update regarding this rather spectacular temple to outsider art, Ron’s Place in Birkenhead outside of Liverpool, a flat hidden within an unassuming brick residence holding a scarcely seen gallery of hearths, altars and murals created by renter Ron Gittin, now catalogued and conserved. The landlord a permissive sufferer of such flourishes was however mostly ignorant of the extent of the artist’s embellishments (as well as his friends and family upon his unexpected death in 2019) that celebrated the multi-hyphenate’s interest in Antiquity and repository of his other creative pursuits. Let’s wish all property owners could be so tolerant of their tenants’ eccentricities and had faith for the next occupant’s inheritance. Much more at the links above.
