But listen! – at the very first crack of dawn,

The ground underfoot begins to mutter,

The woody ridges to quake, and a baying

Of the hounds was heard through the half-light

The goddess was coming,

                                      Hecate

So much the Sibyl said and, ecstatic,

Plunged into the open cave mouth.

– The Aeneid of Virgil translated by Cecil Day Lewis
