So Dupin styles an ecclesiastical writer of the 13th century who wrote a Penitential, which he says was in MS. in the Library of St. Victoire at Paris. But clearly he is mistaken in calling him bishop of Oxford, which see was not erected till 1542. He means Bartholomeus Iscanus, bishop of Exeter (Exoniensis), who was consecrated in 1161, and died Dec. 15, 1184; and who, as Godwin states, wrote several works, a list of which may be seen in Bale. Some letters written to him by John of Salisbury, bishop of Chartres, are still extant. See Godwin, De Praes. Anq. p. 403; Dupin, Hist. of Eccles, Writers, ii, 369; Tanner, Bibl. Brit. p. 78.
