The influence of specific ideas of Grosseteste’s may be found in numerous thinkers, especially those who flourished at Oxford. Their number includes Adam of Wodeham, John Wyclif, Robert Kilwardby, Thomas Bradwardine, Thomas Buckingham, Thomas of York, Walter Burley, William of Alnwick, William of Ockham, and others. But his greatest influence as a philosopher, if we leave aside his commentary on the Posterior analytics, was perhaps as a source of ideas for thinkers flourishing in the first half of the thirteenth century. In particular, Richard Rufus of Cornwall makes extensive use of Grosseteste’s writings in his large Scriptum on Aristotle’s Metaphysics and his Oxford commentary on the Sentences of Peter Lombard, as does his Oxford contemporary Richard Fishacre in his commentary on the Sentences. These thinkers were heavily influenced by Grosseteste’s On Free Decision as well as by his writings on the eternity of the world. Rufus also praises Grosseteste’s scientific and mathematical expertise, as does Roger Bacon, a man by temperament more given to scorn than praise.
