 Contrary to what the marteloio suggests, 370 leagues West of Cape Verde is "not" on the same longitude meridian as 654 leagues West of Seville.Because Seville is well north of Cape Verde, the meridians are clustered closer together at Seville's latitude than at Cape Verde's latitude.A ship sailing west of Seville will, in fact, reach the real Tordesillas meridian (point "T" on map) well before 654 leagues are sailed (point "D").
