 On the other hand, natural treatises reflect the availability of the rich range of mineralogical, botanical and agricultural works, but none of the works by Aristotle on minerals or plants were known to the Arabs. The corpus aristotelicum on animals reached them (apart from the De partibus and the De generatione animalium) in an abridged form under the title of Kitâb al-hayawân, but Epistle 22 On animals is quite far in its content and goals from the Aristotelian corpus. In fact, it places the whole matter within the well-known metaphysical dispute on the superiority of man on animals (besides some attempts of viewing it even in an "ecological perspective"; see, more recently, Darraz 2012; Raymond 2014, 151). .
