EXTRAVAGANTES, 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.
