Lycurgus

but now, by making the power of the senate a sort of ballast for the ship of state and putting her on a steady keel, it achieved the safest and the most orderly arrangement, since the twenty-eight senators always took the side of the kings when it was a question of curbing democracy, and, on the other hand, always strengthened the people to withstand the encroachments of tyranny. The number of the senators was fixed at twenty-eight because, according to Aristotle, two of the thirty original associates of Lycurgus abandoned the enterprise from lack of courage.

But Sphaerus says that this was originally the number of those who shared the confidence of Lycurgus Possibly there is some virtue in this number being made up of seven multiplied by four, apart from the fact that, being equal to the sum of its own factors, it is the next perfect number after six. But in my own opinion, Lycurgus made the senators of just that number in order that the total might be thirty when the two kings were added to the eight and twenty.

So eager was Lycurgus for the establishment of this form of government, that he obtained an oracle from Delphi about it, which they call a rhetra. And this is the way it runs: When thou hast built a temple to Zeus Syllanius and Athena Syllania, divided the people into phylai and into obai, and established a senate of thirty members, including the archagetai, then from time to time appellazein between Babyca and Cnacion[*](Probably names of small tributaries of the river Eurotas.) and there introduce and rescind measures; but the people must have the deciding voice and the power.
