Strait of Gibraltar

As Dati notes in La sfera, the Strait of Gibraltar separates the Ocean Sea (what we would call the Atlantic Ocean) from the Mediterranean Sea. At its narrowest point the strait is 14 kilometers apart, although most of the Sfera maps give it a distance of 16. (We are not sure what mile or unit of measurement Dati was using.) Dati never uses the name Gibraltar in La sfera, preferring instead the truncated stretto, "the strait". The Sfera maps label the Strait with a variety of references, from colonna di hercole (the classical "Pillars of Hercules") to Dati's own stretto, to the fuller gibeltaro (Gibraltar) or stretto in gibilterra (Strait of Gibraltar). Most of these references refer clearly to the strait itself, but there are a few cases (such as ME2) where a solo gibilter reference labels land rather than water, and may be intended to mark the Rock of Gibraltar rather than the Strait.
