TRENT BISHOPRICK, a province of Germany, in the circle of Austria, situated on the Alps, which divides Italy from Germany, and sometimes reckoned part of Italy; it is bounded by Tyrol on the north, by the territory of Venice on the east and south, and by the country of the Grisons on the west, being seventy miles long and fifty broad, subject to the house of Austria.

Trent is also the name of one of the largest rivers in Great Britain, rising in the moor-lands of Staffordshire, and running south-east by Newcastle Under Line, divides that country almost into two equal parts; then entering Derbyshire, turns about to the north-east; and having run the whole length of Nottinghamshire, continues its course due north; at last joining the river Ouse, and several others, it changes its name to that of Hummer, and falls into the German sea below Hull.
