It has been treated by the pen of a Jesuit, the P. de Cerceau whose posthumous work (Conjuration de Nicolas Gabrini, dit de Rienzi, Tyran de Rome, en 1347) was published at Paris, 1748, in 12mo. I am indebted to him for some facts and documents in John Hocsemius, canon of Liege, a contemporary historian (Fabricius Bibliot. Lat. Med. Aevi, tom. iii. p. 273, tom. iv. p. 85).
