Symbolic Meaning of the Number 13: From the Archaic Threshold to Modern Marginalization Introduction: The Number at the Border of Systems The number 13 occupies a unique and paradoxical position in the symbolic universe. It is a number that disrupts the familiar, "perfect" dozen (12) — a structure underlying many cosmological and social models (12 months, 12 signs of the zodiac, 12 apostles, 12 tribes of Israel).
