Problems (Greek: Προβλήματα; Latin: Problemata) is an Aristotelian or possibly pseudo-Aristotelian[1] collection of problems written in a question and answer format. The collection, gradually assembled by the peripatetic school, reached its final form anywhere between the third century BC and the 6th century AD. The work is divided by topic into 38 sections, and the whole contains almost 900 problems.
