Explores himself in vain in every part,
And gives no rest to his distracted heart
DRYDEN, _AEneid_, BOOK VIII.

But fortune again favored the pious chief. In a dream the river god,
Tib-e-ri'nus, arrayed in garb of green, with a crown of reeds upon his
head (old Father Tiber himself, the guardian genius of Rome in later
ages) appeared to him, and told him where to seek help. He repeated
the prophecy of Helenus, about the sow with her litter of thirty
young, and he directed AEneas to repair to Pal-lan-te'um, a city
further up the river, whose king, E-van'der, being frequently at war
with the Latians, would gladly join the Trojans. The good father
promised that he himself would conduct the Trojans along his banks,
and bear them safely on his waters until they reached the Kingdom of
Evander.

"To thy free passage I submit my streams.
Wake, son of Venus, from thy pleasing dreams!
And when the setting stars are lost in day,
To Juno's power thy just devotion pay;
With sacrifice the wrathful queen appease;
Her pride at length shall fall, her fury cease.
When thou return'st victorious from the war,
Perform thy vows to me with grateful care.
The god am I, whose yellow water flows
Around these fields, and fattens as it goes;
Tiber my name--among the rolling floods
Renowned on earth, esteemed among the gods."
DRYDEN, _AEneid_, BOOK VIII.
