In Greek mythology, Clio (Greek: Κλειώ, English: /ˈklaɪ.oʊ/) or Kleio, is the muse of history. Like all the muses, she is a daughter of Zeus and Mnemosyne. She had one son, Hyacinth, with the King of Pieria, Pierus. Some sources say she was also the mother of Hymenaios. She is often represented with a parchment scroll or a set of tablets and is also known as the Proclaimer. The name is from the root κλέω/κλείω, meaning "recount" or "make famous".
KLEIO (or Clio) was one of the nine Mousai (Muses), the goddesses of music, song and dance. Her name was derived from the Greek verb kleô, "to make famous" or "celebrate." In Classical times--when the Mousai were assigned specific literary and artistic spheres--Kleio was named Muse of history. In this guise she was represented holding an open scroll or seated beside a chest of books.
