Description
The importance of the Azores at that time was connected with the observation of Columbus that compass variation (i.e. the difference between the real and the magnetic north) was minimal in that region. A few places in this group of islands were therefore indicated as the first meridian. Only in the second half of the 19th century it was internationally agreed that the first meridian should run through Greenwich.
