(מחזור ויטרי ), is the title of a ritual of the Synagogue of Vitry, in France, compiled about 1100 by R. Simcha of Vitry, a disciple of Rashi, and obtained its name from the place in which the compiler lived. It not only comprises the whole cycle of the daily and festival services, but various legal and' ritual laws from ancient documents. This Machsor, which is of the greatest rarity, has been described by Luzzatto in the Hebrew essays and reviews entitled Kerem Chemed (Prague, 1838), 3, 200. An account of a MS. of this Machsor (British Museum Add. 27,200, 27,201) has also been given by Dr. W. Wright, in the Journ. of Sac. Lit. July, 1866, p. 356 sq. See Fü rst, Bibl. Jud. 3, 483; De' Rossi, Dizionario Storico (Germ. transl.), p. 330 sq. (B. P.)
