Zaratustra's gift in Sacrificatio
The following is a review on the film by Gino Molinari. It starts with a summary of Offret-Sacrificatio and explores the topic of Eternal Return (brought up in the first conversation betweenn Otto and Alexander). The writer also takes an interesting view on Leonardo's "Adoration" and its significance in the film.
