or Robert Grosseteste, Bishop of Lincoln, in the reign of Henry III., the author of some two hundred works. He was accused of dealings in the black arts, and the Pope ordered a letter to be written to the King of England, enjoining him to disinter the bones of the too-wise bishop and burn them to powder. (Died 1253.)
None a deeper knowledge boasted, Since Hodgé, Bacon, and Bob Grosted.
