The stone seats are mentioned only in the description of a judicial assembly: but all assemblies met, there is no doubt, in the same place.
[23] Odyssey II. 14 ἕζετο δ' ἐν ἕζετο δ' ἐν (Τηλέμαχος), ϝεῖξαν δὲ γέροντες (and Telemachus sat down in his father's seat, and the elders made way for him).
[24] See Grote's note in his History, Part I. ch. XX. His instances (Iliad II. 96 and Iliad XVIII. 246) are both taken from time of war: but it is not in the least likely that this detail was peculiar to assemblies held at such times.
[25] Iliad II. 96
ἐννέας δά σφεας
κήρυκες βοόωντες ἐρήτυον, εἴ ποτ' ἀϋτῆς
σχοίατ' ἀκούσειαν δὲ διοτρεφέων βασιλήων
(and nine heralds were calling them to order, to stop clamouring and hearken to the heaven-born kings).
[26] At the Ithacan assembly the suitors Antinous, Eurymachus, and Leiocritus were among the speakers. Odyssey II. 84-254.
