During the Middle Ages, several Latin works which show no connections with his surviving Greek writings have been attributed to the Greek philosopher Aristotle (384/3 BC - 322 BC), one of the greatest intellectual authorities of the period. This manuscript is the only witness of this short text which concerns a dream about the perfection of the philosophers' stone.

It begins on f. 129r and it is introduced by the words Incipit somnium preclarissimi philosophi Aristotelis commentatum a [...] de tota philosophici lapidis perfectione. It starts with the words Vidimus quasi somniantes in templo sancto dei; it ends on the same folio with the words Hec dormienti mihi a deo in somnis revelata sunt quae sapientibus tradenda. Nec rudibus arbitramur.
