Fascinating plan depicting the remnants of Arx Britanica (also called Huis Britten, Brittenberg and Arx Britannica) Roman Castle at the mouth of the Rhine River.
Arx Britanica was fortress constructed by the Romans. The foundation of the fortress was one of the most prominent geological landmarks on the coast of Holland and could be seen at low tide at the mouth of the Middle Rhine. Legend explains that the castle was constructed at the time of the Roman Emperor Caligula, during his conquest of Britain, or by Drusus, with a later alter during the time of Claudius, who conducted an expedition to Britain. By the end of the 17th Century, "the sea had advanced sixteen hundred paces beyond it." Marsch, The Earth and Modfied by Man's Action.
Depictions of the Fortress are quite rare. Abraham Ortelius made a drawing of the building in 1567, which was copied in an engraving dated 1581. Guicciardini produced a map of Arx Britannica in 1612. Langenes also made a small map in 1649, as did Blaeu in the same year. Moll's map of the Netherlands includes a plan.
Abraham Ortelius is perhaps the best known and most frequently collected of all sixteenth-century mapmakers. Ortelius started his career as a map colorist. In 1547 he entered the Antwerp guild of St Luke as afsetter van Karten. His early career was as a business man, and most of his journeys before 1560, were for commercial purposes. In 1560, while traveling with Gerard Mercator to Trier, Lorraine, and Poitiers, he seems to have been attracted, largely by Mercator’s influence, towards a career as a scientific geographer. From that point forward, he devoted himself to the compilation of his Theatrum Orbis Terrarum (Theatre of the World), which would become the first modern atlas.
In 1564 he completed his “mappemonde", an eight-sheet map of the world. The only extant copy of this great map is in the library of the University of Basel. Ortelius also published a map of Egypt in 1565, a plan of Brittenburg Castle on the coast of the Netherlands, and a map of Asia, prior to 1570.
On May 20, 1570, Ortelius’ Theatrum Orbis Terrarum first appeared in an edition of 70 maps. By the time of his death in 1598, a total of 25 editions were published including editions in Latin, Italian, German, French, and Dutch. Later editions would also be issued in Spanish and English by Ortelius’ successors, Vrients and Plantin, the former adding a number of maps to the atlas, the final edition of which was issued in 1612. Most of the maps in Ortelius' Theatrum were drawn from the works of a number of other mapmakers from around the world; a list of 87 authors is given by Ortelius himself
In 1573, Ortelius published seventeen supplementary maps under the title of Additamentum Theatri Orbis Terrarum. In 1575 he was appointed geographer to the king of Spain, Philip II, on the recommendation of Arias Montanus, who vouched for his orthodoxy (his family, as early as 1535, had fallen under suspicion of Protestantism). In 1578 he laid the basis of a critical treatment of ancient geography with his Synonymia geographica (issued by the Plantin press at Antwerp and republished as Thesaurus geographicus in 1596). In 1584 he issued his Nomenclator Ptolemaicus, a Parergon (a series of maps illustrating ancient history, sacred and secular). Late in life, he also aided Welser in his edition of the Peutinger Table (1598).
