Looking at old maps I came across what they say is the oldest known map, that being the Babylonian map of the world.

They said it lists seven island, but only have information on three of them. Has there been any effort in identifying them?

island-"place of the rising sun"
island-"the sun is hidden and nothing can be seen"
island-"beyond the flight of birds"

Also is there any corolation between seven islands and seven continents?
