Tliis reference is important, because it places those grammatico- 
logical treatises, which gave a distinctive character to the logic of 
the moderni, outside of the “nova logica.” 
In the Liber Decanorum of the University of Prague, the Vetus 
ars Aristotelis is always kept separate from the books of the Prior 
and Posterior Analytics, the Topics, and the book on Fallacies; f 
and this division is elsewhere referred to as that of “ Vetus ” and 
Nova Logica.” J 
Ascbbacb, in bis history of the University of Vienna, says that 
the Ars Vetus treated of the Predicables of Porphyry, and of the 
Categories or Predicaments, and of the de Interpretatione of 
Aristotle. The Logica Nova looked at argumentation as a whole, 
and considered—(1.) The Resolution or analyses of syllogisms given 
in the Prior and Posterior Analytics; (2.) Inventive, or ways of 
discovering true middle terms, given in the Topics; and (3.) 
Fallacies, given in the libri Elenckorum. Prof. Ascbbacb shows 
that Logic, as taught in Vienna, consisted of three parts—the 
Vetus Logica, which was studied as an introduction; the Parva 
Logicalia, for the Vienna Students were Moderni; and the Nova 
Logica.§ The lists which be quotes bears out bis statement, with 
this exception, that after some time the Parva Logicalia, not the 
“ Ars Vetus,” came to be looked on as the introduction to Logic. || 
These quotations may, perhaps, serve to prove our assertion, that 
the scholastic use of the terms “vetus” and “nova logica” is 
almost exclusively confined to the designation of parts of the

lists a course of lectures on the Ars Vetus cost 5 groschen, but, if taken with 
exercises and colloquia, or qusestiones, it cost 18 groschen. A course on the 
Parva Logicalia cost 10 groschen, including queestiones. While a course on 
the Nova Logica cost 12 groschen, and 36 including qusestiones (p. 95). In 
the last decade of the 14th century, the course on the Parva Logicalia con¬ 
sisted of 104 lectures, and cost a gulden ; the length of the course on the 
Vetus Logica was the same, and the fee the same ; while the courses on the 
Nova Logica consisted of 132 lectures, and the fee was 35 groschen (p. 352).
