  On Proclus’ works see Beutler (1957), 190–208, Saffrey-Westerink (1968), lv–lx, Rosán (²2009), 266–274, and especially Luna–Segonds–Endress (2012), as well as the short overview given below (1.2). Although a large part of his numerous writings is lost, some major commentaries on Plato have survived (though incomplete) and some important systematic works. Moreover, later Neoplatonists such as Damascius, Olympiodorus, Simplicius, and Philoponus have conserved many extracts of lost work, but these fragments have never been collected (see now, however, Luna–Segonds–Endress (2012)).
