Erato

Erato, who presides over the poems of love, generally accompanies the youngest and gayest of the Muses, Terpsichore.

Erato, in Greek mythology, one of the nine Muses, whose name signifies loving or lovely.

The Villanelle has been called "the most ravishing jewel worn by the Muse Erato."

But compare statistically the service and the detriment, for Clio must instruct Calliope and Erato.
