GENTILLET, zhan''ti''lye', INNOCENT: French Reformed jurist; b. at Vienne; d. at Geneva, the dates of his birth and death being unknown. After the massacre of St. Bartholomew he fled to Geneva, but after the peace of 1576 was made head of the council of Die, and became president of the Parliament of Grenoble a short time later. He was deprived of his position, however, by an edict of 1585, whereupon he seems to have again sought refuge in Geneva. One of his two political works, the Diacoura our lea moyerta de bier gouverner et maintenir en borne pain un royaume ou suite print cipautE . . . contre Nicolas Machiavel Florentin (Geneva, 1576), was translated into English by S. Paterieke, A Discourse upon the Means of Wei Governing . . . a Kingdom . . . against N. Maehiavell (London, 1602). His Apologia pro Christiania Gallic religionis evangelicd aeu reformats (1578) ranks as one of the best defenses for the Reformation, while his Le Bureau du co7:cile de Trente (1586) forms one of the ablest attacks upon the Council of Trent.

GENTILLYzhän"ti"yi' (GENTILIACUI), SYNOD OF, 767 An assembly mentioned in the Frankish annals, at which, in the presence of Greek and Roman emissaries, the doctrine of the Trinity, especially the procession of the Holy Spirit, and image-worship were discussed. It took place at Gentilly, a southern suburb of Paris, and was occasioned by a Byzantine embassy which had probably come for the purpose of winning the Frankish Church to the standpoint of Constantine V. on the question of image-worship. The proceedings and resolutions of the synod are not known. The question concerning the procession of the Holy Spirit was only secondary and was probably stirred up by the papal nuncios for the purpose of sowing discord between the Franks and Greeks. There seems to have been no agreement, and this is only natural in consideration of the political conditions of Italy and the resolutions of the synod at Constantinople in 754 against image-worship.

GEOFFREY OF MONMOUTH (Galfridus or Gaufridus Arturus, Galfridus Monemutensis; Welsh Galffrai or Gruffyd ap Arthur): English chronicler; b., probably at Monmouth, c. 1100; d. at Llandaff 1154. He is thought to have been a monk of the Benedictine abbey at Monmouth, and about 1140 was made archdeacon of Llandaff. He was consecrated bishop of St. Aeaph Feb. 24, 1152, but seems to have died before he actually entered on his duties there. Geoffrey is famous for his Historia reguna Britannia, which was highly popular in all lands during the Middle Ages, furnished Sir Thomas Malory the material for his Mort d'Arthur, and has been drawn upon by poets from Shakespeare to Tennyson. It is a skilful mixture of history, legend, and pure romance, beginning with the fall of Troy and the story of Brutes, a descendant of lEneas, who is made the ancestor of the Britons, and ending with Cadwalader and the downfall of the Celtic power in Britain. The main source, Geoffrey states, was a "very old book" given him by Walter, archdeacon of Oxford, but he also used Gildas, Nennius, and Bede. The seventh of the twelve books appears to have been originally an independent work of Geoffrey's (De prophetiia Merlint). The text has been published by J. A. Giles (London, 1844) and in Gottfried's von Monmouth Historic regum. Britannia and Brut Tysylio . . . herausgegeben von San. Marie [A. Schulz] (Halle, 1854); transl. by Aaron Thompson, The British History (London, 1718), revised -and corrected by J. A. Giles, Geoffrey of Monmouth's British History (1842).
