The World Upside-Down

The World upside down

The convention that North is at the top on most modern maps was established by the Egyptian astronomer Ptolemy (90-168 AD) and was adopted by other cartographers.

The World upside down and centered on Indonesia

In modern times, reversed maps are made as a learning device or to illustrate Northern Hemisphere bias.

  1. I for one think Australia belongs on top!
    My husband and I are spending a few days in Amersfoort for Christmas with his cousin. I hope you turn on some good weather for us - it's my first cold Christmas.

    1. On the bright side: Amersfoort covered in snow is beautiful: But I don't think that will happen, a White Christmas is rare over here.

  2. Well that’s different. I enjoy looking at old maps but it hasn’t improved my geography skills and I can’t read modern maps either.

  3. Good one Rob, it shows how a small change in perception can make a big difference.

  4. Italy and New Zealand would remain (almost) antipodes and mirrored :-)
