DUBOIS, PIERRE (Petrus de Bosco). — Writer, born c. 1250 at Coutances or its vicinity (Normandy), died c. 1321. Between 1269–72 he studied in Paris. In 1300 he was advocate for royal causes at Coutances, an office which from 1306 he also exercised in the service of Edward I of England.
A typical figure of a medieval writer, he played an important part in the struggle of Philip the Fair against the Church, especially in the controversies involving Boniface VIII and the Templars. His most significant writings on this subject are the *Deliberatio super agendis a Philippo rege contra epistolam Bonifacii papae VIII* and the *Supplication du peuple de France au roi contre Boniface VIII* (ed. P. Dupuy, *Histoire du différend*, etc., Paris 1655, pp. 44 for the first and 214–19 for the second). His principal work, dedicated to Edward I of England, is the *De recuperatione Terrae Sanctae* (ed. V. Langlois, Paris 1891).
