Abraham Ortelius’ map of two French regions. That on the left is the region of Le Mans with the city at the centre. On the right is Brittany and Normandy. The map was first published in the ‘Additamentum’ to Ortelius’ ‘Theatrum Orbis Terrarum’ of 1595. This example with Spanish text on the verso is from the 1602 edition of the ‘Theatrum’. The Le Mans is derived from a map by Matthaeus Ogerius in 1539. That of Brittany and Normandy from various sources but primarily Gerard Mercator’s map of 1585. Van der Broecke cites also Bertrand d’Argentre’s (1519-90) map of Brittany from 1588 and Lezin Guyet. This is an example of the first state. Abraham Ortelius (1527-98) developed an interest in cartography, geography, and history at an early age. He began as a ‘kaarten afzetter’ (or illuminator of maps) and would purchase single maps from booksellers and colour them for re-sale, mounted on linen suitable for wall-hanging. At twenty he was entered in the Guild of St Luke at Antwerp. Ortelius travelled extensively in Europe, and maintained regular correspondence with mapmakers, historians and scientists, acquiring information, which was to form his greatest opus, the ‘Theatrum Orbis Terrarum’. What made the atlas stand out as the first modern atlas was its uniformity. They were produced in a similar style and none of the ancient Ptolemaic maps were included. The atlas was accompanied a catalogue of the authors whose source Ortelius had drawn upon in compiling the work. Without this list many cartographers of the day would remain unknown to us today. From its first appearance in 1570, the ‘Theatrum’ was far more comprehensive in scope than any contemporary work. In all, over forty different editions were published, with text in Latin, Dutch, German, French, Spanish, English or Italian, with the maps being frequently revised or replaced. By 1612, when the final edition was published, the atlas contained no less than 128 maps. Provenance: private Jersey collection.
