Theophrastus, Aristotle's successor, wrote an encyclopedic book Opinion of the Physicists that was the standard work about the pre-Socratics in ancient times.

The disciple of Aristotle who wrote a digest on the opinions of the pre-Socratic philosophers was Andronicus of Rhodes. Andronicus was a Greek philosopher and scholar who lived in the 1st century BC and was a leading figure in the Peripatetic school, which was founded by Aristotle. He is known for his work on the teachings of Aristotle and the pre-Socratic philosophers, and for his contributions to the development of the study of logic. Andronicus is credited with creating the first systematic summary of the works of Aristotle, which became known as the "Old Logic," and with producing a digest of the opinions of the pre-Socratic philosophers, which was known as the "Preambles".
