Gerber (1997), p. 104 (see also n. 5); p. 105 n. 8. Gerber states that "most critics have been convinced" by Jaeger's defence of fr. 12 as Tyrtaeus' work (Five Essays. 1966 [1932]. pp. 103–42), but that Fränkel (EGPP. pp. 337–39) assigns it "to the time of Xenophanes" and G. Tarditi ("Parenesi e arete nel corpus tirtaico". 1982. RFIC 110. pp. 257–276) to shortly before Pindar's Pythian 10 (498). Gerber, Douglas E. (1997). A Companion to the Greek Lyric Poets. Brill.

"After listening to Phoebus, they brought home from Pytho the god's oracles and sure predictions. The divinely honoured kings, in whose care is Sparta's lovely city, and the aged elders are to initiate counsel; and the men of the people, responding with straight utterances, are to speak fair words, act justly in everything, and not give the city (crooked?) counsel. Victory and power are to accompany the mass of the people. For so was Phoebus' revelation about this to the city."—adapted into prose from Plutarch, Life of Lycurgus 6, and Diodorus Siculus World History 7.12.5–6, by Gerber (1999), p. 41. Gerber, Douglas E.
