 Themistius interpreted that since Aristotle said that the heavenly body (coelum) is in place per accidens, he assumed another heavenly body to be in place (I add, per se) and Averroes explains “another heavenly body” as all celestial spheres, orbium. According to Themistius, per accidens is such a wide category that the commentators before him did not find the term adequate and they said the heavenly body to be in a place because of its parts. Themistius and Averroes share the view that Aristotle here was using the term per accidens freely (LC 141M). Themistius is a highly regarded authority but Averroes will formulate his own solution.
