“ Tyrwhitt first pointed out the person here alluded to, and says—'there is some account of him in Panzirolus, de Cl. Leg. Intrepret. l. iii. c. xxv:—Joannes, a Lignano, agri Mediolanensis vico, oriundus, et ob id Lignanus dictus,' &c. One of his works, entitled Tractatus de Bello, is extant in MS. Reg. 13 B. ix [Brit. Mus.] . He composed it at Bologna in the year 1360. He was not however a mere lawyer. Chaucer speaks of him as excelling in philosophy, and so does his epitaph in Panzirolus. ”
