They marched in a long line, fastened to each other by chains and ropes and heavy "gorees" or slave-sticks. The latter implements were poles from six to seven feet long, with a fork at the end of each, in which the necks of the men were fitted and secured by means of an iron bolt, passing across the throat and riveted at both ends. To render marching possible with such encumbrances, the men went in couples, one behind the other, so that the slave-stick of the leading man could be tied to the stick of his fellow behind, which was slewed round to the front for the purpose. Their wrists were also tied, some in front, others behind their backs. Secured thus, Hercules himself might have been reduced to obedience, especially if he had felt the frequent sting of the cruel lash that was laid on these captives.
