The oldest sailing directions, dating back to the middle ages, descended directly from the Greek and Roman periplii: in classical times, in the absence of real nautical charts, navigation was carried out using books that described the coast, not necessarily intended for navigation, but more often consisting of reports of previous voyages, or celebrations of the deeds of leaders or rulers.

Only the eight principal winds (N, NE, E, SE, S, SW, W, NW) were given special names. The eight half-winds just combined the names of the two principal winds, e.g. Greco-Tramontana for NNE, Greco-Levante for ENE ...
