Η Λαβρύς ( Μινωϊκός Πέλεκυς)

Ancient Greek Civilization - Αρχαία Ελλάς

''Labrys'' - Minoan doubleheaded bronze axes
Labrys (λάβρυς in Greek, lábrys) is the term for a symmetrical doubleheaded axe originally from Crete in Greece, one of the oldest symbols of Greek civilization; to the Romans, it was known as a bipennis.
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.
