The Monophysites for their part were not disposed to compromise with the hated Greeks, and periodically imperial conciliation was replaced by savage per- secution. Thus the breach with the Levant provinces was never bridged ,and they were ripe to fall to any invader who would offer them greater freedom from imperial interference.
