a town of Gloucestershire, 90 miles from London, on the borders of Oxfordshire and Berks, and the great road to Gloucester; had anciently a nunnery, and a priory of black canons. In this parish is Clay-hill. The market is on Tuesday: and it has two fairs. It is supposed to have been a Roman town; for a plain Roman road runs from hence to Cirencester; and by a digging in a meadow near it some years ago, an old building was discovered, supposed to be a Roman bath, which was 50 feet long, 40 broad, and 4 high, supported with 100 brick pillars, curiously inlaid with stones of divers colours of tesserae work. Letchlade The Leech, the Coln, the Churn, and Ifis, which all rise in the Cotswold hills, join here in one full stream, and become one river, called the Thames, which begins here to be navigable; and barges take in butter, cheese, and other goods, at its quay, for London.
