Averse, with planted feet, and, from the right,
Tugged at the solid stone with all his might.
Thus heaved, the fixed foundations of the rock
Gave way; heaven echoed at the rattling shock.
Tumbling, it choked the flood: on either side
The banks leap backward, and the streams divide;
The sky shrunk upward with unusual dread,
And trembling Tyber dived beneath his bed.
The court of Cacus stands revealed to sight;
The cavern glares with new-admitted light.
