Pseudo-Dionysius and Transubstantiation

Q. Did Pseudo-Dionysius advocate the Roman dogma of transubstantiation?

Pseudo-Dionysius, the Areopagite (c. 5th Century A.D.):

And sacredly observe this, that the divine Symbols [συμβόλων] placed upon the holy altar, by which Christ is signified [σημαίνεται] and partaken of, etc. (J. P. Minge, Patrologiæ Cursus Completus, [1857], Patrologiæ Græcæ, Tomus III, S. Dionysii Aeropagitæ, De Ecclesiastica Hierarchia, Cap. III, § IX, Col. 437). Here Trans. (J. H. Treat, The Catholic Faith; Or, Doctrines of the Church of Rome Contrary to Scripture and the Teaching of the Primitive Church, [1888], p. 226). Here

But these things being celebrated according to the rite  spoken of, the priest, standing before the holy Symbols [συμβόλων], washes his hands with water, etc . (J. P. Minge, Patrologiæ Cursus Completus, [1857], Patrologiæ Græcæ, Tomus III, S. Dionysii Aeropagitæ, De Ecclesiastica Hierarchia, Cap. III, § X, Col. 437). Here Trans. (J. H.
