ABSTRACT
The contours of what was to become medieval Latin scholastic philosophy began to emerge in the eleventh century and became rather clear in the first half of the twelfth. In the formative years grammar and logic were the predominant disciplines. In grammar, Priscian, a sixth-century Latin pupil of Apollonius Dyscolus from the second century, was the auctor read by people who wanted to study serious linguistics. In logic, the auctor was Aristotle whose works, as opposed to Priscian’s, came with a number of auxiliary treatises, of which one, Porphyry’s Isagoge, had a status almost equal to Aristotle’s own works. The following table shows the parts of the Latin Organon that the medievals inherited from late antiquity and the most important companion volumes:
