From Burnet's Note on the Sources
The fragments of the pseudo-Plutarchean Stromateis, quoted by Eusebios in his Praeparatio
Evangelica, come from a source similar to that of the best portions of the Philosophoumena. So far
as we can judge, they differ chiefly in two points. In the first place, they are mostly taken from the
earliest sections of the work, and therefore most of them deal with the primary substance, the heavenly
bodies and the earth. In the second place, the language is a much less faithful transcript of the original.
