Very desirable and early town-plan of Frankfurt am Main in a second state.
"An impressive bird's-eye view from the southwest of the powerful trade city of Frankfurt, in 1605 home to 20,000 people. St Batholomew's cathedral, coronation church of the German kings and emperors, stands on the hill at the core of the original settlement on the right bank of the Main. On the Römerberg hill further left, the Römer and Goldener Schwan houses served as the town hall from 1405 onwards, to their right lies the Gothic councillors' church of St Nicholas. Identified in the Sachsenhausen quarter are the church of the Magi (H. Drei Konig), which became Frankfurt's first Protestant church in 1525, and the house of the Teutonic Knights (Teutsch Hauss). Frankfurt had been established as an international trade-fair center and city of commerce in the Middle Ages: its autumn fair had been running since the 12th century and the spring fair since 1330. By around 1600 the book fair in this publishing city had already assumed international proportions.
Frankfurt's commercial and fair activities meant that countless different currencies were in circulation. Around 1585 exchange rates and rules of trade were introduced, in a move seen as marking the birth of the Frankfurt stock exchange.
In 1147 Frankfurt was also assured a special position within the Empire, as the site of the election of German kings, a role officially confirmed by the Golden Bull of 1356. From 1562 to 1792 the coronation of the Emperor also took place in Frankfurt cathedral.." . (Taschen, Braun and Hogenberg, p.95.)

From volume one of the greatest publication in this genre!. The Civitates was compiled and written by George Braun, Canon of Cologne Cathedral. Braun gathered together vast amounts of information and draft plans to produce over 500 city views/maps published in six parts between 1572 and 1617. Most of these engravings were made by Simon Novellanus and Frans Hogenberg, many after drawings by Joris Hoefnagel.
