Know, at Æeta'a court a maiden dwells
Deep skill'd by Hecate in magic spells:
All plants she knows that grow on mountains steep,
On vales, or meads, or in the boundless deep;
By these she quells the fire's relentless force,
Stops the mad torrent in its headlong course,
Retards the planets as they roll on high,
And draws the Moon reluctant from the sky.
Lines 567–574 - Argonautica (3rd century BC) - Book III
