This is a fascinating map of the ancient lands of Gaul as described by the commentaries of Julius Caesar.

This map was created by Nicholas Sanson (1600-1667), who is considered to be the father of modern French cartography.  Sanson at one point was a tutor of King Louis XIII.  

This map was printed in Paris in 1649 and is in very good condition.

Framed, the map measures 30.5" x 23".  The map itself is approximately 23.5" x 16".
