Query: Tribute to an astronomer: the work of Max Ernst on Wilhelm Tempel   In 1964-1974, the German artist Max Ernst created, with the help of two
friends, a series of works (books, movie, paintings) related to the astronomer
Wilhelm Tempel. Mixing actual texts by Tempel and artistic features, this
series pays homage to the astronomer by recalling his life and discoveries.
Moreover, the core of the project, the book Maximiliana or the Illegal Practice
of Astronomy, actually depicts the way science works, making this artwork a
most original tribute to a scientist.
