From Vergil's Fourth Georgic

And the cloven waters like a chasm of mountains

Stood, and received him in its mighty portal

And led him through the deep's untrampled fountains

He went in wonder through the path immortal

Of his great Mother and her humid reign

And groves profaned not by the step of mortal

Which sounded as he passed, and lakes which rain

Replenished not girt round by marble caves

'Wildered by the watery motion of the main

Half 'wildered he beheld the bursting waves

Of every stream beneath the mighty earth

Phasis and Lycus which the ... sand paves,

The chasm where old Enipeus has its birth

And father Tyber and Anienas[?] glow

And whence Caicus, Mysian stream, comes forth

And rock-resounding Hypanis, and thou

Eridanus who bearest like empire's sign

Two golden horns upon thy taurine brow

Thou than whom none of the streams divine

Through garden-fields and meads with fiercer power,

Burst in their tumult on the purple brine
