The Commons file doesn't exist at that exact filename, and Wikidata has no indexed record for it — which tracks with what you're saying about not being able to relocate it.\n\nA few things that may help narrow it down:\n\n- Do you remember anything about the image itself — was it a street-level shot looking east through the gate, or west from Pariser Platz? Any figures or carriages visible?\n- Do you have the original file saved locally? If so, the filename often carries a Commons slug (e.g. `Bundesarchiv_Bild_...` or `Berlin_1899_...`).\n- Do you remember the institution or collection it was attributed to — Bundesarchiv, a museum, or listed as anonymous/unknown?\n\nIf you can share any of those details I can try alternative Commons file paths.

Langhans — the \"1899\" date would be when the photograph was taken, not the gate's construction date\n- **Likely public domain** given the age, but the license depends on the original source institution\n\nThe fact that it's being sold commercially suggests it may have originated from a digitised archive (Bundesarchiv, a press agency, or a private collection) and been licensed out — which would explain why it's hard to pin down on Commons.\n\nA couple of quick questions to help me stage what we can accurately:\n\n1. In your `sourceMaterials` field you noted it was \"sourced from Wikimedia Commons\" — do you think this was an honest mistake in memory, or is there a chance a version of it does exist on Commons under a different filename?\n2. The album-online listing — does it show a photographer credit or institution?

So I couldn't find historical photos of the other 8 gates, so I started taking my own photographs of whee the gate was, and then started to deconstruct the painting process, a little in the next 4 and then a lot in the last 4.

I always liked paintings at points when they wern't finished, but didn't want to stop then and say its finished, so work the techique out fully, but knew in a way that this was the time to do this. maybe coming back to europe the envioremnt is more open to concept and deconstruction"},{"role":"assistant","content":"That's a really clear arc — eight paintings in the established technique, then a deliberate evolution through the second half of the series, using your own photographs where history ran out and progressively exposing the process.

A photograph of the Brandenburg Gate taken in 1899 is transferred via acrylic gel medium directly into the canvas surface and painted with flat colour fields using a palette calibrated to Berlin's character at the time: notably more muted than the San Francisco works that preceded it. The canvas is fully painted — no process stages exposed — placing it at the beginning of a deliberate arc that would see the technique progressively deconstructed across the sixteen paintings of the Gates of Perception series.\n\nThe series maps the locations of the original Berlin customs wall gates — the Akzisemauer — which predate the Cold War wall by over a century. The Brandenburg Gate is the only one of these gates still standing, making it both the literal and symbolic starting point. The discovery that the customs wall gates overlapped with the Cold War wall, and that their names persist in U-Bahn stations across the city (Kottbusser Tor, Hallesches Tor), prompted a different way of reading Berlin's divisions — one in which the Cold War wall appears as an imposition over a longer, more organic urban history that the city is visibly returning to.\n\nThe 1899 photograph was selected from a large pool of available images for its compositional energy: the walkway draws the eye toward a centred gate with a directness that anchors the painted fields around it. The work sold at the Kunstmarkt at Museumsinsel, Berlin, in 2023, and is now in a private collection in the Netherlands. It remains the most recognised image Bolter has made of Berlin.","agentDraftConceptualKeywords":["Brandenburg Gate","Gates of Perception","Berlin customs wall","Akzisemauer","transfer painting","acrylic gel medium","historical photograph","urban history","city palettes","organic vs imposed division","Cold War wall","series origin","Kreuzberg studio","flat colour fields","process deconstruction","iconic image","Richard Hamilton","seamless integration","Wikimedia Commons source","private collection"],"agentDraftFormalContribution":"This painting establishes the originating logic of the Gates of Perception series — the customs wall gates as outward-facing markers of urban growth, in deliberate contrast to the Cold War wall's logic of enclosure. As the first work made on arrival in Berlin, it represents both a continuity with the San Francisco transfer paintings and the starting point of a deliberate evolution: fully painted here, progressively deconstructed across the sixteen works that follow. The choice of the 1899 photograph positions the painting at the intersection of two timelines — the photograph's moment and the painting's making — while the subject extends that span further, placing contemporary Berlin within the longer history of the city's walls and gates. It is the most publicly recognised work in the Berlin body of work, and the image that made the less obvious subjects of the series possible."}},{"sessionId":"8c8713ad-ea80-4dad-9d9b-e7a85bd00504","sessionType":"artwork-cataloguing","createdAt":"2026-05-30T12:38:51.520Z","completedAt":"2026-05-30T13:51:07.514Z","primaryArtwork":"brandenburger-tor-1899","mentionedArtworks":[],"artistRecord":{"firstImpression":"The work has a photo from 1899 of the Brandenburg Gate looking west, there are some people walking in old time clothes and there is a lady with an umbrella, I painted the walkway that they are on in yellow, so a bit of a yellow brick road.

After the 1806 Prussian defeat at the Battle of Jena-Auerstedt, Napoleon was the first to use the Brandenburg Gate for a triumphal procession, and took its quadriga to Paris. After Napoleon's defeat in 1814… the quadriga was restored to Berlin. It was then redesigned by Karl Friedrich Schinkel for the new role of the Brandenburg Gate as a Prussian triumphal arch.\"\n\n**C — Description:**\n> \"The central portion of the gate draws from the tradition of the Roman triumphal arch, although in style it is one of the first examples of Greek Revival architecture in Germany. The gate is supported by twelve fluted Doric columns, six to each side, forming five passageways. Citizens were originally allowed to use only the outermost two passageways on each side.\"\n\n**D — 18th-century reconstruction:**\n> \"Frederick William II of Prussia was determined to establish his capital of Berlin as a cultural centre. Berlin lacked the monuments and cultural life of Vienna, Paris or London. He summoned new German architects to Berlin, including Carl Gotthard Langhans from Breslau, who was appointed director of the Royal Office of Works in 1788.\"\n\n**E — Introduction:**\n> \"The Brandenburg Gate is an 18th-century neoclassical monument in Berlin. It was erected on the site of a former city gate that marked the start of the road from Berlin to Brandenburg an der Havel.

The first painting in the Gates of Perception series, made in Berlin in 2017.","agentDraftDescriptionLong":"Brandenburger Tor. 1899 is a transfer painting on canvas, 80 × 80 cm, made in a rented studio on Reichenberger Strasse, Kreuzberg, in 2017 — the first work in the Gates of Perception series. The source is a photograph by Lucien Levy taken in 1899, showing the gate from the east looking west across the Pariser Platz. Figures in period clothing populate the foreground; a woman with an umbrella stands near centre.\n\nThe photograph is transferred via acrylic gel medium directly into the canvas surface. Over it, flat colour fields define the scene: a yellow walkway runs through the middle ground toward the gate, blue fills the sky, green marks the trees to the left, grey and brown hold the surrounding buildings. The yellow arrived during painting rather than by plan — and once there, it reframed the entire image. The cobblestone path becomes a yellow brick road, an aspirational passage through a gate that was, within living memory, sealed off by the Berlin Wall and left stranded in the death strip for nearly three decades.\n\nThe Gates of Perception series maps the locations of the old Berlin customs wall gates — structures that predate the Cold War wall and were named outward, for where you were going. The Brandenburg Gate is the only one still standing. In 1899, it marked the threshold between city and the Tiergarten; by 1961 it was unreachable from either side. The yellow road in the painting reaches back past that rupture, recovering the gate as a place of passage. The palette — restrained throughout except for that single warm note — reflects a conscious recalibration on arrival in Berlin, leaving behind the brighter colours of earlier San Francisco work in favour of something that fitted the city as it actually was.","agentDraftConceptualKeywords":["transfer painting","acrylic gel medium transfer","colour fields","urban landscape","historical photograph","Berlin","Brandenburg Gate","Gates of Perception","customs wall","Cold War","passage","yellow brick road","palette recalibration","seamlessness","time","memory","city history"],"agentDraftFormalContribution":"This painting establishes the originating logic of the Gates of Perception series — the customs wall gates as outward-facing thresholds rather than barriers — through a single unplanned formal decision: the yellow walkway. The colour was not premeditated but arrived during painting and reoriented the entire image, transforming a documentary 1899 street scene into something closer to myth. The restraint of the surrounding palette (blue, green, grey-brown) isolates the yellow and gives it disproportionate weight. The work also marks the moment Bolter consciously broke from the San Francisco palette and began developing a city-specific colour approach — a shift that would carry through the entire Berlin body of work. As the first of eight paintings made simultaneously, it set the conceptual and chromatic terms for the series that followed."}}]}
