# Celestial Atlas carries the structure and Photomicrography appears as the accent.

Produce four original images that take their structure from Celestial Atlas (style, 17th–19th century) and their accent from Photomicrography (technique, 1840s–).

## What to make

Make the kind of thing Celestial Atlas exists for: double-page plates for books and exhibitions on astronomy or navigation, or showing a whole body of knowledge on one sheet with its ornament intact. Choose one subject and hold it across all four.

## Structure comes from Celestial Atlas

- Myth figures over stars
- Concentric celestial structure
- Gold and blue coloring
- Ornamented cartouches

Composition: Concentric spheres at the center, four corners filled with cartouches. Type and lettering: Title inside an ornamented frame, star names tiny and italic.

## Accent comes from Photomicrography, used sparingly

- Structures beyond sight
- Specimens on black
- Polarized and fluorescent color
- The wonder of symmetry

Let one material quality come from it: Separate tissues by polarized or fluorescent color and record the basis.

## Colour and feeling

Build the ground on #e7ddcc, carry the structure in #b18651 and #39485c, and let a single accent come from #5778b7. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: exhilaration, luxury, calm, technique.

## Where they fight

- Celestial Atlas and Photomicrography stand roughly 190 years apart. Keep one of them recognisably period rather than letting both drift into the middle.

## What goes wrong

- Celestial Atlas: Drawing the myth figures so large that the star positions vanish leaves a plate working neither as diagram nor as ornament.
- Photomicrography: Scale bar and magnification get dropped while the color is being made beautiful, and the result becomes decoration that no longer works as a scientific figure.

## Across the four

Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period languages described above.
