The library also formerly contained a rich collection of MSS., but many of them have been lost or removed.
Cavaillon (anc, Cahellio), a town of Provence, France, in the department of Vaucluse, on the Durance, 14 m. S. E. of Avignon; pop. in 1866, 8,304. It has an active trade in raw silk, fruits, and preserves, and manufactories of vermicelli and madder. During the revolution its fortifications were destroyed. It was an ancient Roman town, but having been repeatedly pillaged by barbarians, and having suffered much from an earthquake in 1731, it has few remains of antiquity. The most remarkable of its ruins is a triumphal arch supposed to have belonged to the Augustan age. The country round Cavaillon is justly called the garden of Provence.
