Among the fragments, we may distinguish
In Tim. fr. 3 as it discusses the particular
function of grades of daemons and also shows the relationship between
the grades, correcting
his predecessors on the matter and
In Tim. fr. 6, which discusses the place of the Demiurge in Syrianus’ structure of the cosmos, as well as how the placement of the
Demiurge corresponds to his function.
In Tim fr. 11 is also important, as it gives
evidence of Syrianus’ explanation of Platonic arithmetic and geometry in
terms of ontology.
The connection between geometry and hierarchical
metaphysics is also to be found in Syrianus’
In Met. 85.38-86.2, but his thought becomes clearer through Proclus’ elaboration, as Wear rightly points out.
In Parm. fr. 5 is also of key importance, as it shows how Syrianus develops the system of Platonic principles, in which reality is
the result of the conjunction of Limit (Monad in the
In Metaphysica) and Unlimitedness (Dyad in the
In Metaphysica).
