Tyrtaeus 12

Tyrtaeus 12.

1-9: I would not remember or set in speech a man for speed, size, good looks, wealth, kingliness, or speech, or any virtue,

10-22: unless he is good in war, the greatest prize for the polis and demos, risking his soul enduring on the front lines and encouraging his comrades.

23-34: if he dies, all will mourn him and build a tomb; his fame will live forever, and despite being underground he will become immortal

35-42: if he lives, all will honor him distinguished among the citizens, and the young and old will yield their seats to him

43-4: so let each man try to reach this peak of virtue, refusing to yield in war

Language and ideas are generally similar to Homer. I think the biggest differences are in the rewards / ideological justification for fighting in the 'if he dies' and in the 'if he lives' sections.

If he dies: At least some Homeric heroes get tombs and immortal kleos for dying in battle (though now that I think about it it's actually pretty rare in Homer), but here we have explicit reference to hero cult; the idea of immortality in the tumbos is more like Pindar.

If he lives: Homeric heroes are generally pretty big on the physical spoils and markers of status, e.g. the famous Sarpedon bit in Iliad 12 puts a lot of emphasis on seating at the feast, better cuts of meat, and the sacred precinct they own. None of that here; people are respected in the demos, but no physical advantages as far as I can tell.

Not sure I see any traces of polis-ideology here, or at least any more than in Homer. Like:

ξυνὸν δ᾿ ἐσθλὸν τοῦτο πόληί τε παντί τε δήμῳ, (Tyr. 12.15)

is not too far off from

πατρί τε σῷ μέγα πῆμα πόληΐ τε παντί τε δήμῳ, (Il. 3.50)
