Who was Abraham Ortelius?

I love this game, every so occasionally you get a great history question.

barbit58, the 15th century is mentioned in a wrong answer (the monk). In the comments are presented only the years: 1570,1537,1554, 1560 etc (no century)

I despair! 1570

I despair since when has 1570 been in the 15th century?????
