Aphrodite (Greek: Ἀφροδίτη; Latin: Venus) is the Greek goddess of love and beauty.
Aphrodite was associated with Golden Apple of Discord by Eris and with magic girdle. The word ΚΑΛΛΊΣΤῌ (Ancient Greek: kallistē, Modern Greek: kallisti; "for/to the most beautiful") was inscribed on the Golden Apple of Discord by Eris. Καλλίστῃ is the dative singular of the feminine superlative of καλλός, beautiful.
