She presided over history, and is represented as crowned with laurels, holding in one hand a trumpet, and in the other a book. Sometimes she holds a plectrum or quill with a lute. Her name signifies honour and reputation, ἀξίας, gloria; and it was her office to record faithfully the actions of brave and illustrious heroes. Clio had Hyacintha by Pierius, son of Magnes.
