The first Pseudo-Aristotelian works were produced by the members of the Peripatetic school, which was founded by Aristotle.
Attaching his name to such a work guaranteed it a certain amount of respect and acceptance, since Aristotle was regarded as one of the most authoritative ancient writers for the learned men of both Christian Europe and the Muslim Arab lands.
These can be separated into three groups based on the original language used for the work, namely Latin, Greek or Arabic.
The majority of these cover occult subjects, such as alchemy, astrology, chiromancy and physiognomy.
Others treated Greek philosophical subjects, more often the Platonic and neoplatonic schools rather than the thought of Aristotle.
