Structural cues: Curving horizons; Exaggerated landmarks; Extreme wide-angle views; Painterly color. Accent cues, used sparingly: Radiating rhumb lines; Names perpendicular to coasts; The vellum ground; Flags and monsters as ornament. Composition: Curve the horizon strongly and stretch the featured area toward the viewer. Type and lettering: Vertical brush lettering for place names, larger for the famous ones. Let one material quality come from the second style: Black and red on a vellum ground, flags and monsters in open water. Mood: Exhilaration, Nostalgia, Play, Trust. Color: build on #e9e6dd, #67635d, #171615 with a single accent drawn from #e9e6dd, #67635d, #171615. Constraints: do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work. Produce an original composition in the general period languages described above.

# Where the two fight
# - Both belong to Diagrammatic Expression, so the difference is small. Push the roles further apart than feels comfortable.
# - Roughly 1900 years apart. Keep one of them recognisably period rather than letting both drift into the middle.

# Cautions carried from each entry
# - Hatsusaburō Panoramic Map: Pushing curve and exaggeration until the order of the route breaks gives a map that is fun to look at and useless on the ground.
# - Portolan Chart: Drawing rhumb lines as pattern while ignoring how they answer the roses gives ornament that no longer looks like an instrument of navigation.
