I’m currently working on a document about security in Africa, and particularly in Southern Africa, which is translated as Afrique australe in French. Austral dates back to 1372 and comes from Auster, which, in Roman mythology, is the name of the Southern wind. This is also where the name Australia (Terra Australis) comes from.
In Roman mythology, the other winds are: Aquilo (North), Eurus (East) and Favonius (West). In Greek mythology, they are called Notus (South), Boreas (North), Eurus (East) and Zephyrus (West).
