Made in 1924. It was the only movie that remained after Viking
Eggeling. He would die in 1925.

A first movie of him, Horizontal-vertical Orchestra, is lost.

Try to watch it with and without sound: you'll realize the perfect
equivalence between the structures used by the musical language and
the structures used by the cinematic language.

Actually his movie is a cinematic ballet, which was fertile space for
Eggeling to find the equivalence with the harmonic and contrapuntal
structures. Hans Richter, Man Ray or Walter Ruttmann were on the same
page, naturally, each one with his own differences. I think now at
Maya Deren: her movies were looking for something different in dance:
sublimated ritual. No wonder that one of her movies is named just
that, Ritual in Transfigured Time; but all her movies are about myth,
and ritual, and dance.
