Categoriae decem
The Categoriae decem (Latin for "The Ten Categories"), also known as the Paraphrasis Themistiana ("Themistian Paraphrase"), is a Latin summary of Aristotle's Categories thought to date to the 4th century AD. Traditionally credited to St Augustine, it is now variously attributed to Themistius or Pseudo-Augustinus. From the eighth century onwards, this text became one of the major sources of logical teaching in medieval Europe, where it was taken at times as a full translation of Aristotle's work, rather than a compression.
