Multicultural revisionism. So what? Who cares if the Arabs depicted Britain as an island in the 12th century? The Emperor Claudius conquered Britain way back in 42 BC and annexed into the Roman Empire even. The Romans (dead white Europeans, and therefore no longer a part of the the progress of Western civilization -- they seemingly only represent slavery, death, and oppression in the new PC world of history) were clearly aware of Britain's island status. Indeed they were aware of the island status of Ireland too. It was Agricola who said Ireland could be conquered with only one legion. I'm sure that Britain as an island appeared on numerous Roman maps -- it's just that none of them survived (that we know of).
Correction -- that should be 43 AD, not BC.
No one is slighting Italian contributions to science in this exhibition, even if it gets mentioned MMMCDXII times.
Didn't he also develop a soft drink that never really took off until centuries later - under a more appealing name?
And that from a person who couldn't conquer Wales with any number of legions.
You are right of course. This is so embarrassing I cannot believe the media dunces are making a deal of this.
The map is more than the conquest. Celts conquered Britain in 500 BCE and they knew too that it was island, but they did not have civilization to produce maps.
