If the ecliptic on a earth-globe is marked off in 365 days, should the Julian date plus the 21 day off-set be at the latitude of the sun at high noon on that date? If so it would amount to a graphic solar table.
You would find the appropriate tic mark for the corrected Julian date scale to the latitude on the globe and site your sextant. The error would give your latitude.
