A fascinating map of Andalusia, Spain, showing the two principal cities of Cadiz and Seville. The mountains surrounding the river valleys are beautifully drawn as hills, and the Atlantic Ocean is shown with a variety of ships at that time as well as mythical sea monsters. There is a naval battle depicted off Cadiz. For his unprecedented achievement in issuing his atlas, and also for his thoughtful and rigorous methodology, Ortelius belongs amongst the first rank of cartographers. He is very aptly called ‘the father of modern cartography.’ Ortelius based this map on his own work assembled from previous maps but also from mariners who landed in Antwerp and Amsterdam.
