7 Furthermore, neither can D. Schulckenius in my opinion sufficientlie prooue, that Ioannes de Poliaco, whose errours were condemned by Pope Iohn the 22. in that Extrauagant Vas electionis, was this Ioannes Pa∣risiensis, who made the Treatise of Kingly and Papall power, but some other Doctour of Paris, who was called by that name, and liued about that time.

Fourthly, neither is, there any Authour that I haue read, who doth affirme, that Ioannes Parisiensis,
