One of the two elegiac poems that Critias addressed to Alcibiades (fr. 5 W.2) may contain a further allusion to the Theognidean sylloge, in addiction to the one concerning the sphragis (seal). Such an hypothesis seems to be supported by Libanius’ testimony (Decl. 1,62) about the criticism Socrates once directed at the supposedly alluded verses (Theogn. 173-178). It therefore seems plausible that they were well known to both Critias and Alcibiades and perhaps even used by the former to convey an anti-democratic message.
