[B] AUKBOROUGH. Dr. Stukely having discovered a Roman castrum and a vicinal road here, supposed it to be the Aquis of Ravennas. The Roman station is square, each side 300 feet; the entrance is at the north, and the west side faces the steep cliff that over-hangs the Trent. The situation of this castle at the north-west angle of Lincolnshire, renders it a kind of watch tower over Nottingham and Yorkshire, which it surveys. The camp is now called "Countess Close," and tradition speaks of a Countess of Warwick having resided here. The vallum and ditch are nearly entire; a square plat called the "Oreen," is supposed to have been appropriated for the soldiers when on duty. Within this is a round walk into a labyrinth, called Julian's Bower; these bowers are usually found in the neighbourhood of Roman towns, and are objects of great curiosity to uninformed people. Dr. Stukeley is of opinion that they were the arena of some of their ancient games, brought into Italy from Troy, and that they derived their name from "borough," any work consisting of ramparts of earth, and not from "bower" an arbour. The views in this neighbourhood are very beautiful; the winding Trent with its rich level plains of meadow, all alive with herds of cattle; the cliff, commanding a noble view of the three rivers; the hanging woods and ornamented walks, all form a great contrast to what Lincolnshire is often represented by those who have visited only the fenny parts of this fertile county.

The Propraetor, Ostorius Scapula, was accustomed to ferry his legions over near this place. In the time of Edward the Elder, who was lying here with his army, Llewellyn, Prince of Wales, was stationed at Beachley, on the opposite bank. Llewellyn, who was required to pay homage to the English Sovereign, refused to cross the passage; but Edward immediately crossing in a boat, was seen, as he approached the shore by Llewellyn, who, overcome by the condescension, rushed into the water, and taking the monarch upon his shoulders, carried him to land, and did him homage for the principality. The Severn is here nearly two miles across. [Sidenote: Celebrated passage into South Wales.]
