The Archive borrows the order of a museum catalogue without pretending that every object in it survived from the past.

Its method exists to protect a simple promise: visitors should always be able to tell what is invented, what is interpretive and what is historically documented.

Record classifications

Speculative Design

This label is used for an original design created for The Blue Brass Archive. The object may be informed by genuine materials, manufacturing traditions and period forms, but the particular design is not presented as an authenticated historical artefact.

A Speculative Design record can include an imagined date, maker, workshop, commission and provenance. Those details belong to the archive narrative unless a note explicitly identifies them as documented history.

Alternative History

This label is used when the principal subject is an invented event, institution, exhibition, journey, biography or document placed within recognisable history. Alternative History may involve real cities and historical figures. Its purpose is not to falsify the record but to explore a plausible cultural path that history did not take.

Historical Reference

This label is reserved for real subjects supported by sources. Historical Reference entries may interpret design, symbolism or social context, but dates, names and material claims should be traceable. Sources are listed wherever they materially support the article.

The catalogue record

Archive dossiers use a consistent set of fields: archive reference, fictional or historical date, creator and role, workshop, place of origin, materials, purpose and collection. A fictional date belongs to the world of the object; it is not the WordPress publication date and is never offered as proof of real provenance.

The record status—such as Catalogued, Restored, On Display or Missing—describes the object inside the archive narrative. The classification label explains the editorial nature of the record. The two serve different purposes.

Visual consistency

Every important design receives an immutable object specification before additional views are made. It records overall dimensions, proportions, component count, placement, materials, colour and the relationship between moving and fixed parts.

For example, Vileišis No. 01 is a low horizontal instrument with exactly three main circular indicators, two fluted brass columns, two upper cobalt-enamel panels, one central moon-phase window and one flat Carrara marble plinth. A later image may reveal the rear access panel or show the object in a library, but it may not add a fourth dial, move the moon window or invent a cabinet beneath the marble.

Close views are checked against the complete object. A material detail must come from a visible, physically possible junction. When an image creates a surface or compartment that the master object does not possess, the image is rejected or corrected.

Plans, sections and mechanisms

The Archive may publish front elevations, cutaway-style illustrations, old-advertisement compositions and patent-inspired plates. These are artistic documents. Unless a record is explicitly identified as a reproduction of a historical technical source, they are not working engineering drawings.

No fictional instrument is supplied with structural calculations, electrical specifications, pressure ratings, fabrication tolerances or a guarantee that it can be manufactured safely. The aim is visual culture and narrative coherence, not a disguised construction manual.

Historical people inside fictional records

A real person may provide the historical gravity around which a speculative design is built. When that happens, the Archive distinguishes the person’s documented life from the invented attribution. In the opening collection, Petras Vileišis is a real Lithuanian engineer, publisher and entrepreneur; the atmospheric observatory attributed to him is an original speculative design.

The same rule applies to real buildings, cities and institutions. Their documented features are not silently altered. Alternative events and commissions are identified as such.

Digital image-making

Archive images may combine art direction, digital construction, photographic references and generative tools. They are edited as a controlled series rather than accepted as independent accidents. The relevant standard is not how quickly an image was produced, but whether it obeys the object specification and communicates the intended materials and scale.

Corrections

The Archive treats corrections as part of cataloguing. Historical errors, unclear labels and visual contradictions may be reported through the Contact page. Substantial corrections should be made in the record itself rather than hidden in a passing note elsewhere.
