What is it about?
This paper examines the value of the sixth century AD Platonist Simplicius for the study of nature written by the fourth BCE philosopher Theophrastus. The latter’s work is not preserved except in fragmentary passages but Simplicius adds helpful information to reconstruct the work entered ‘Physics’.

Why is it important?
Without an assessment of Simplicius’ comments on the structure and content of Theophrastus’ Physics, we would not be able to reconstruct the work. This reconstruction in turn helps to put the continuity of Aristotle’s studies on nature in historical context as well as the further developments and innovations.
Perspectives
It is remarkable that the transmission of Theophrastus’ works in writings produced nine centuries later can help to reconstruct his Physics, although he was often marginalised next to his teacher and mentor Aristotle.
