William de la Mare, de Mara, or Lamarensis, may have studied at Oxford[1389] before he went to Paris, where he was a disciple of Bonaventura. In 1284 he published a criticism of Thomas Aquinas, called Correctorium operum fratris Thomae[1390], which afterwards won for him the title of standard-bearer of the Anti-Thomists[1391]. This treatise, which may perhaps be still extant in an Italian library, is generally known only through the reply to it, attributed sometimes to Aegidius Romanus, but with more probability to Richard Clapwell[1392]. ‘The serious part of the work of William de Lamarre,’ says M. Charles, ‘seems directly inspired by Bacon[1393].’ He had no doubt come under Roger’s influence either at Oxford or Paris. William de Mara appears also to have written in favour of a strict observance of the Rule of St. Francis. In a dispute on the interpretation of the Rule in 1310, Friar Ubertino de Casali, one of the leaders of the ‘Spiritual’ party, quoted, in support of his views,
‘the opinion of St. Francis expressed in his Rule, and of Pope Nicholas in his Declaration, of Friar Bonaventura in his Apologia, of Friars Alexander and Rigaldus ... and of Friar John de Peckham in his book on Evangelical Perfection, and of Friar William de Mara, who were all solemn masters of our Order[1394].’
