Agis and Cleomenes (Agis.19.2-Agis.19.3)

But at a certain point the road branched off towards the prison, and when they were come to that place, Amphares, by virtue of his office, laid hands on Agis and said: I shall lead thee, Agis, to the ephors, to answer for thy measures of state; and Damochares, who was tall and robust, threw his cloak about the king’s neck and dragged him along.

Others pushed him along from behind, as had been agreed, and since he had no helper but was without a friend, they thrust him into the prison. At once Leonidas was at hand with a large band of mercenaries and surrounded the prison, while the ephors went in to Agis. After sending for those of the senators who were of the same mind as themselves, as though the king were to have a trial, the ephors ordered Agis to defend his conduct of affairs.
