The obscure history of James or Jacobus Baradaeus, or Zanzalust may be gathered from Eutychius, (Annal. tom. ii. p. 144, 147,) Renau dot, (Hist. Patriarch. Alex. p. 133,) and Assemannus, (Bibliot. Orient. tom. i. p. 424, tom. ii. p. 62 - 69, 324 - 332, 414, tom. iii. p. 385 - 388.) He seems to be unknown to the Greeks. The Jacobites themselves had rather deduce their name and pedigree from St. James the apostle.
