Both maps below show Eritrea highlighted. At 15° Mercator inflates Eritrea by only about 8%, so the two maps largely agree on it. Watch what the old map does to Saudi Arabia beside it. That contrast is why the new world map matters.
At 15°, Eritrea sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
