CITY OF REGENSBURG (RATISBONA)

A large two-page woodcut. In the foreground is the Danube, on which the city is located at the influx of the Regen. It is a well-fortified place. Shipping is indicated by a number of flat-bottom boats loaded with merchandise in barrels. Two bridges mentioned in the text. To defend the Danube the Romans extened a line of fortifications—the limes, as they were called, which began at Regensburg, and keeping well to the north of the river, were carried to the neighborhood of Stuttgart. A circular stonewall on this side of the river contains a drawbridge which leads to a gate, above which are the armorial bearings of the city—keys crossed in a field of red. The unfinished church of St. Peter appears in the center of the city. From one point of the wall chains extend to a peculiar side-wheeler, apparently used for stretching these chains across the river for defense.
