P. Vergilius Maro, Aeneid
John Dryden, Ed.

Inclos'd with hills, a winding valley lies,
By nature form'd for fraud, and fitted for surprise.
A narrow track, by human steps untrode,
Leads, thro' perplexing thorns, to this obscure abode.
High o'er the vale a steepy mountain stands,
Whence the surveying sight the nether ground commands.
The top is level, an offensive seat
Of war; and from the war a safe retreat:
For, on the right and left, is room to press
The foes at hand, or from afar distress;
To drive 'em headlong downward, and to pour
On their descending backs a stony show'r.
Thither young Turnus took the well-known way,
Possess'd the pass, and in blind ambush lay.
