The blue and white stripes represent the eternal waves from the Aegean Sea from where, incidentally, emerged the mythical Goddess of beauty, Aphrodite! The nine stripes are symbolic of the letters of the Greek word for ‘freedom’. – Ελευθερία (Eleftheria). The nine syllables of the national slogan “Ή ΕλευθερίΑ” “Ή ΘάνατοΣ” (Eleftheria i thanatos) mean Freedom or Death.
