This entry illustrates LSJ's e)/naulos (B) I.2. In this sense the adjective e)/naulos, -on is connected with musical practice, literally meaning "in the pipe" (au)lo/s; cf. Maximus of Tyre, Dialexeis 1.7.a5-6; Hesychius epsilon2700); hence the metaphor lo/gos e)/. "ringing in the ears", then "fresh in memory". See e.g. Plato, Menexenus 235C and Laws 678C; Lucian, Dream 5; and further, next note.
[1] The headword is masculine accusative singular or neuter nominative/accusative singular of the adjective. It must be quoted from somewhere, very probably -- in which event it will be neuter -- Aeschines 3.191, on recalling his father's memories of the restoration of democracy to Athens in 403/2; cf. the scholia there.
[2] George of Pisidia, Heraclias fr. 34 Tartaglia. Here, the Suda transmits o(rma\s krei/ttonas bouleuma/twn, suggesting a genitive of comparison. The original text, however, reads o(rma\s kreitto/nwn bouleuma/twn: impulses for better decisions, a genitive of value construction. That the Pisidian's sense is the latter seems to be confirmed by the last two lines of the fragment (not given by the Suda):
(/otan ma/lista kai\ kata/llhlon fu/sin teqhgme/nhn eu(/rwsin ei)s eu)tolmi/an (especially when they also encounter an adequate nature and a readiness for boldness). Tartaglia notes (233, note 91) that the Pisidian's fragments 31-36 relate to events before Heraclius's (cf. eta 465 generally) attack on the Persians at Nineveh (cf. nu 415, Barrington Atlas map 89 grid F4) in early December 627. Fragment 34, in particular, refers to the Persian general Rhazates (cf. PLRE IIIb s.v.) who decided to alter the order of his lines before the battle, but was defeated and killed; cf. Tartaglia op. cit.
