2.  Earliest occurrences of the name of the sea

  Prehistoric people moved little from the area they inhabited, therefore, if it was a seacoast, they called the sea without any specific name, just ¡°the sea¡±. In later times, when people realized that their sea was not the only one, did they begin to give specific names to seas.
The ancient Greek scholar Strabon, who lived between 60 B.C. and 20 A.D., referred to the sea as Okeanos, the ocean surrounding the known world. Publius Comrnelius Tacitus(cca 55-117 A.D.) gave a brief description of the geography, ethnography and society of German lands and people in his work ¡°Germania¡±(1). In its first chapter he writes that the River Rhenus(Rhine) flows into the Northern Ocean(Oceanus Septenttrionalis). Thereafter he only refers to ¡°the ocean¡±. In Chapter 2. he adds that the name ¡°Germania¡± is rather new, as those who first crossed the Rhenus and drove the Gauls away were called Germans.
Apart from these the earliest mentioning I know of the sea is Pliny Jr.(¡°Germanicum Mare¡±) and of course Ptolemy(¡°Germanikos Okeanos¡±). They date from the 1st and 2nd centuries A.D. respectively(2).
Abraham Ortelius¡¯historical atlas, called Parergon (1594), does not confirm Pliny¡¯s use of Germanieum-Mare. ¡ªlt states, that he used the names ¡°Oceanus Septenttrionalis¡± and ¡°Oceanus Britannicus¡±.
