The etching was published in Antwerp in 1649 and was inserted into Topographia Bohemiae, Moraviae et Silesiae (Topographia Germaniae), published 1650. He left shortly after to create another perspective, his great view of London in 1647. On the middle sheet is a legend with a signature where Hollar says that the etching was based on drawings, taken in 1636. In 1636 with his new patron, Thomas Howard, he returned briefly from German lands to Prague and then went to England.
