The Piri Reis map that we read about yesterday is not the only 'old map' out there.
Indeed, there are a lot of old maps.
One of those is the Ptolemy World Map which is reported to have been made in the 2nd century.
A reconstruction of that map made in the 15th Century is the DIT picture of the day. It came, of course, from good old Wikipedia.
Hmmm. Seems a lot of reconstructions of maps were made in the 15th Century, aka the 1400s.
Why?
Probably because of all the exploration that was taking place in that era.
Anyway, The Ptolemy map and many many other old maps or their reconstructions are still in existence.
