Lorenz Stöer is a German artist who lived most of his life in the 16th century. His major work as an engraving artist is the series published about perspective and geometric shapes, you can see some of these woodblock prints in the current blog post.
The artist was heavily influenced in his craft by another German artist of his time, Albrecht Dürer. Although it is not obvious when you see the prints, you can still feel some elements of style that are quite similar.
