Slow creeping onwards; while amazed the foe,

Beheld, and thought some subterranean gust

Had burst the caverns of the earth and forced

The nodding pile aloft, and wondered sore

Their walls should stand unshaken. From its height

Hissed clown the weapons; but the Grecian bolts

With greater force were on the Romans hurled;

Nor by the arm unaided, for the lance
