Labrys (Greek: λάβρυς, lábrys) is the term for a symmetrical double-bitted axe originally from Crete in Greece, one of the oldest symbols of Greek civilization; to the Romans, it was known as a bipennis. The symbol was commonly associated with female divinities.
The double-bitted axe remains a forestry tool to this day, and the labrys certainly functioned as a tool and hewing axe before it was invested with symbolic function. Labrys symbolism is found in Minoan, Thracian, and Greek religion, mythology, and art, dating from the Middle Bronze Age onwards, and surviving in the Byzantine Empire.
Plutarch relates the word labrys with a Lydian word for "axe": (Λυδοὶ γὰρ ‘λάβρυν’ τὸν πέλεκυν ὀνομάζουσι). Labrys was a cult-word that was probably introduced from Anatolia, where such symbols have been found in Çatal Höyük from the neolithic age. In Labraunda of Caria the double-axe accompanies the storm-god Zeus Labraundos. The root is Aegean (compare Laubranda, Lerna etc.), and the word labyrinth (house of the double axe), which is Pre-Greek, is possibly derived from labrys.R. S. P. Beekes also rejected an Indo-European etymology and proposed a Pre-Greek one; he also suggested that labrys has the same root as labyrinthos.
