or MOSUL, a town of Turkey in Asia, seated on the western bank of the river Tigris, nearly opposite to the place where Nineveh formerly stood. It is a large place, surrounded with high walls; but the houses are ill-built, and in several places gone to ruin; however, it has a strong castle and a citadel. It is a place of great trade, particularly in cloth and all sorts of cottons and silks. At some distance from Mosul is a mosque, in which they pretend the prophet Jonah lies. The inhabitants are generally Mahometans; but there are a great number of Nestorian Christians. It was besieged in vain by the Persians in 1743. E. Lon. 41° 45'. N. Lat. 35° 30'.
