"The Atlas of True Names reveals the etymological roots, or original meanings,
of the familiar terms on today's maps of the World and Europe.

For instance, where you would normally expect to see the Sahara indicated,
the Atlas gives you "Sea of Sand", derived from Arab. es-sahra "desert, sea of sand".

The 'True Names' of 1500 cities, countries, rivers, oceans and mountain ranges
are displayed on these two fascinating maps,
each of which includes a comprehensive index of derivations."
