Lycurgus

The training of the Spartans lasted into the years of full maturity. No man was allowed to live as he pleased, but in their city, as in a military encampment, they always had a prescribed regimen and employment in public service, considering that they belonged entirely to their country and not to themselves, watching over the boys, if no other duty was laid upon them, and either teaching them some useful thing, or learning it themselves from their elders.

For one of the noble and blessed privileges which Lycurgus provided for his fellow-citizens, was abundance of leisure, since he forbade their engaging in any mechanical art whatsoever, and as for money-making, with its laborious efforts to amass wealth, there was no need of it at all, since wealth awakened no envy and brought no honour.
