Bernardo Bellotto (1721-1780) was one of the most famous painters of what's called "veduta", a genre of painting that specializes in cityscapes. Probably using a "camera obscura", he was able to create highly accurate depictions of the various cities that he was active in, ranging from Rome in Italy, to Dresden in Germany, and Warsaw in Poland. His paintings provide us with a glimpse into 18th century Europe.
