Over the film, more than 70 esoteric messages can be found: both on a visual, musical and script level.
"Giuliano Kremmerz Street", address which Mia gives to the taxi driver as hers at the beginning of the film, doesn't actually exist. It's a tribute paid to a famous Italian alchemist.
Mia cuts a cake in her house: this cake is half-moon shaped, like those baked by witches to celebrate their rites.
On the blackboard in Mia's kitchen there's a writing that says "Eliphas Square": it's another famous esoterist.
When Eva tells Orlando "Do as thou wilt!", she is making reference to a famous quote belonging to Aleister Crowley. By contrast, at the end of the film, Eva will say to her French friend "Love and do what you want", citing one of Saint Augustine's most renowned expressions.
