In the night all cats are black. Darkness erases distinctions — social, moral, material. When light and scrutiny are absent, all people are equal in their anonymity, and all deeds look the same. It can warn about the concealment night provides to wrongdoers, or describe the levelling of social difference in the dark.
Sicily's nights — especially in the rural interior before electricity — were truly dark. The darkness was not a modern inconvenience but a fundamental fact, and it changed the rules of social life. The noble and the peasant, walking through the same dark vicolo, were indistinguishable. Assignations, negotiations, and crimes all moved into the night because the night made them invisible. This proverb captures that ambiguity. It is used to point out that appearances, class, or status cannot be read in darkness — which is both equalising and dangerous. It warns against being deceived by what you cannot properly see, and against trusting those who operate in the dark. It also carries a note of democratic irony: in the dark, the distinctions that matter so much in daylight become meaningless.
Known in variant forms across Europe; the Sicilian version reflects specifically the darkness of rural and pre-industrial Sicily where night truly transformed social and moral geography.
