Philoponus, On Aristotle’s Categories 5.15–20

Next is the third heading, where in Aristotle’s writings one should start. Well, Boethus of Sidon says that one should start from the treatment of physics, since this is more familiar and knowable for us, and one should start from the things that are more clear and knowable. But his teacher, Andronicus of Rhodes, examining [the issue] more exactly, said that one should first begin with logic, which is concerned with demonstration.

Elias, On Aristotle’s Categories 117.17–25

Let us investigate three things, where to start on Aristotle’s writings, where to end, and the route between. We make this investigation not only because of the number of [the writings] but also because of the disagreement among the ancients; for some said that one should begin with physics, some with logic, others with ethics, others from mathematics. Boethus of Sidon says with physics; Andronicus of Rhodes, the eleventh of the successive heads of the Aristotelian school, said with logic, and of the Platonists some with ethics, others with mathematics.
