AUST, a chapelry, in the parish of Henbury, union of Thornbury, Upper division of the hundred of Henbury, W. division of the county of Gloucester, 4¼ miles (W. S. W.) from Thornbury; containing 191 inhabitants. This place derived its name, anciently Austre Clive, signifying "the southern cliffs," from its situation on the south bank of the Severn, among bold and lofty cliffs projecting into the river, which is here two miles in breadth. About half a mile below the village, which is surrounded by salt marshes, and immediately opposite to the estuary formed by the junction of the Severn and the Wye, is the ferry called the Old Passage, supposed to have been the Vectis of the Romans. Alabaster is procured in great quantities; and those rare minerals, the sulphate and carbonate of strontian, are found in the cliffs which line the banks of the Severn. The chapel is in the ancient English style. The place is distinguished as having been the residence of Wycliffe.
