Either a stone jar or a prison. The Greek word εo (kermos) means either an earthen jar or a prison, as in ε εε (chalko en keram), in a brazen prison. When Venus complained to the immortals that Diomed had wounded her, Din bade

Thus we say, “He was sent to the treadmill, meaning, to prison to work in the treadmill.
