canon law. This is the name given to the constitutions of the popes posterior to the Clementines; they are thus called quasi vagantes extra corpus juris, to express that they were out of the canonical law, which at first contained only the decrees of Gratian; afterwards the decretals of Gregory IX., the sexte of Boniface. VIII., the Clementines, and at last the extravagantes were added to it. There are the extravagantes of John XXII., and the common ‘extravagantes.’ The first contain twenty epistles, decretals or constitutions of that pope, divided under fifteen titles, without any subdivision into books. The others are epistles, decretals or constitutions of the popes who occupied the holy see, either before or after John XXII. they are divided into books like the decretals.
