The Problems (or Problemata) is an Aristotelian or possibly pseudo-Aristotelian collection of problems written in a question and answer format as its authenticity has been under questioning. The collection, gradually assembled by the peripatetic school, reached its final form anywhere between the third century BC to the 6th century AD. The work is divided by topic into 38 sections, and the whole contains almost 900 problems.
Later writers of Problemata include Plutarch, Alexander of Aphrodisias, and Cassius Iatrosophista.[1]
