Like Adelard also he withdrew from the schools of Gaul after teaching there for a time--longer apparently than Adelard; like Adelard he followed the guidance of reason and took an interest in natural science; like him he employed the dramatic dialogue form in his works. John of Salisbury, who studied grammar under William of Conches and Richard Bishop (_l’Évêque_) from about 1138 to 1141,[120] represents those masters as successors to the thorough-going educational methods and humanistic ideals of Bernard of Chartres; but adds that later, when men “preferred to seem rather than be philosophers, and professors of the arts promised to transmit all philosophy to their hearers in less than three or two years’ time, overcome by the onslaught of the unskilled multitude, they ceased teaching.”[121] William then seems to have entered the service of Geoffrey Plantagenet, to whom as duke of Normandy as well as count of Anjou we find William addressing his _Dragmaticon_ or _Dramaticus_, which takes the form of a dialogue between them. It thus was written at some time between 1144 and 1150, the period when Geoffrey was duke of Normandy.[122] His son, the future Henry II of England, was in Normandy from 1146 to 1149, when William appears to have been his tutor.[123] In the _Dragmaticon_ William praises Geoffrey for training his children “from a tender age” in the study of literature,[124] and before the boy was made duke of Normandy by his father in 1150 at the age of seventeen William prepared for his perusal a collection of moral extracts from such classical Latin authors as Cicero, Seneca, Juvenal, Horace, Lucan, and Persius, entitled _De honesto et utili_.[125] The last we hear of William seems to be in 1154, under which date Alberic des Trois Fontaines,[126] a thirteenth century chronicler, states that he had attained a great reputation. He might well have lived on for some time after that date, since his former associate, Richard Bishop, was archdeacon of Coutances
