The phrase ἶβις Λυκούργῳ functions as a specific, contemporary allusion to the trial of the general Nicias in 415 BCE, where he was mocked for his alleged resemblance to the ibis (or, more accurately in this context, the grotesque association of the ibis with the effeminate or foreign). However, the primary force here is the juxtaposition of the ibis (a bird associated with Egypt and the god Thoth) with Lycurgus, the legendary Spartan lawgiver. This creates a jarring anachronism and cultural clash: Lycurgus is the archetype of Spartan austerity, while the ibis is an Egyptian symbol. The scholia suggest this may be a reference to a specific physical resemblance or a metaphorical insult regarding Lycurgus's character or appearance that was current in the 410s, though the precise nature of the 'resemblance' is lost to history. The second half, Χαιρεφῶντι νυκτερίς, is a direct insult to the philosopher Chaerephon (Socrates' friend), calling him a 'night-jar' or 'owl,' likely alluding to his nocturnal habits or, more likely, his association with Socrates (who was often compared to a gadfly or associated with the owl of Athena, but here the 'night-jar' is a derogatory term for a bird of ill omen or a clumsy, nocturnal creature). The sentence relies entirely on the audience's knowledge of these specific individuals and the cultural connotations of the birds in 5th-century Athens.
