Some writers say that he actually consulted the allies about the advisability of selling the whole population for slaves, in which debate the Theban erianthus proposed to destroy the city and make the site of it a sheep walk.
"Plutarch's Lives, Volume II"
Aubrey Stewart & George Long
To quote from Plutarch, Life of Lysander: The proposal was made in the congress of the allies, that the Athenians should all be sold as slaves; on which occasion erianthus, the Theban, gave his vote to pull down the city and turn the country into sheep-pasture; yet afterwards, when there was a meeting of the captains together, a man of Phocis singing the first chorus in Euripides' Electra, which begins,- Electra, Agamemnon's child, I come Unto thy desert home, they were all melted with compassion, and it seemed to be a cruel deed to destroy and pull down a city which had been so famous, and produced such men.
