The Principles of Wayfinding

Every rose begins at a single known meridian
The sixteen-point compass rose anchors all bearing — Tramontana, Greco, Levante — each wind named and fixed before the helmsman casts off.
A rhumb line holds the course the helmsman cannot
These straight lines on the chart trace constant angles across open water — not the shortest crossing, but the one a vessel can steer true.
Red-lettered harbors anchor the unknown coastline
Each inscribed port — Genova, Barcelona, Candia — confirms the navigator's reckoning and offers safe haven when the wind turns hostile.
Thirty-two winds compose the mariner's tongue
From the eight principal bearings to the sixteen quarter-winds, every named direction in the rose is a sky the pilot can read.
