From Gerard Mercator’s edition of ‘Claudii Ptolemaei Tabulae Geographicae Orbis Terrarum’. It was in 1578 that one of the world’s greatest cartographers put out an edition of the earliest surviving geographical treatise. This map centres on the north west portion of Africa dominated by modern day Morocco. The Straits of Gibraltar are also shown. Koeman Me 5; Nordenskiold 234; Norwich no. 294; Phillips, P.L.
