(ll. 36-52) Come thou, let us begin with the Muses who gladden the great spirit of their father Zeus in Olympus with their songs, telling of things that are and that shall be and that were aforetime with consenting voice. Unwearying flows the sweet sound from their lips, and the house of their father Zeus the loud-thunderer is glad at the lily-like voice of the goddesses as it spread abroad, and the peaks of snowy Olympus resound, and the homes of the immortals. And they uttering their immortal voice, celebrate in song first of all the reverend race of the gods from the beginning, those whom Earth and wide Heaven begot, and the gods sprung of these, givers of good things. Then, next, the goddesses sing of Zeus, the father of gods and men, as they begin and end their strain, how much he is the most excellent among the gods and supreme in power. And again, they chant the race of men and strong giants, and gladden the heart of Zeus within Olympus,--the Olympian Muses, daughters of Zeus the aegis-holder.
(ll. 53-74) Them in Pieria did Mnemosyne (Memory), who reigns over the hills of Eleuther, bear of union with the father, the son of Cronos, a forgetting of ills and a rest from sorrow. For nine nights did wise Zeus lie with her, entering her holy bed remote from the immortals. And when a year was passed and the seasons came round as the months waned, and many days were accomplished, she bare nine daughters, all of one mind, whose hearts are set upon song and their spirit free from care, a little way from the topmost peak of snowy Olympus. There are their bright dancing-places and beautiful homes, and beside them the Graces and Himerus (Desire) live in delight. And they, uttering through their lips a lovely voice, sing the laws of all and the goodly ways of the immortals, uttering their lovely voice. Then went they to Olympus, delighting in their sweet voice, with heavenly song, and the dark earth resounded about them as they chanted, and a lovely sound rose up beneath their feet as they went to their father. And he was reigning in heaven, himself holding the lightning and glowing thunderbolt, when he had overcome by might his father Cronos; and he distributed fairly to the immortals their portions and declared their privileges.
