About 500 B.C., the northern parts of Greece were generally referred to as Europe and soon thereafter the name was applied not only to Greece, but to the whole continent.
According to another theory, promoted by many researchers, the word Europe comes from the Semitic word "erebu", which means "sunset". This is because when we look from a Middle Eastern viewpoint, the Sun sets over Europe.
In the same way one could say that the name Asia comes from the word "asu", which means "sunrise".
Additionally, in Greek mythology, Europa was a Phoenician princess who was abducted by the god Zeus disguised as a bull.
She was taken to Crete where she later gave birth to Minos who became the King of Crete.
