 Damascius recorded that he returned in 538 to his home country of Syria (Hoffmann 1994: 590–591). Did the others follow him, or did they return to Athens, Syria, or Harran (ancient Carrhae, in the north of Mesopotamia, close to the Syrian border)? This question has not been satisfactorily answered (for the ongoing discussion, see Goulet &amp; Coda 2016: 343–346; Watts 2005: 290–298). However, it seems clear that, in order to write his commentaries—which, as most scholars assume, were composed after returning from Chosroes’ court (I. Hadot 2014: 135)—Simplicius needed quite an extensive library. Therefore, he could only have returned to a place that provided such a library.
