The “wind rose,” a circular directional emblem found on vintage maps and charts, evolved from the primary wind directions schematically arranged around a circle that represented the horizon.

In the 16th century, cartographers expressed their most imaginative work within the rose, incorporating brilliant colors of gold- and-silver laced trims. Maintaining some means of uniformity, principal winds, half-winds and quarter winds were in different colors.

Italian cartographers used gold, green and red hues. Cherubs were added -- blowing the principal winds from their mouths -- sometimes accompanied by animals.

Where the compass and GPS set our course today, the wind rose was the primitive directional indicator on navigational charts.

More tomorrow.
