Zorns Lemma

Zorns Lemma is a 1970 American structuralist film by Hollis Frampton. It is named after Zorn's lemma (also known as the Kuratowski–Zorn lemma),a proposition of set theory formulated by mathematician Max Zorn in 1935. Zorns Lemma is prefaced with a reading from an early grammar textbook. The remainder of the film, largely silent, shows the viewer an evolving 24-part "alphabet" (where i & j and u & v are interchanged) which is cycled through, replaced and expanded upon. The film's conclusion shows a man, woman and dog walking through snow as several voices read passages from On Light, or the Ingression of Forms by Robert Grosseteste.
