As where for the protection of the walls Many and many moats surround the castles, The part in which they are a figure forms, Just such an image those presented there; And as about such strongholds from their gates Unto the outer bank are little bridges, So from the precipice's base did crags Project, which intersected dikes and moats, Unto the well that truncates and collects them.
