The term "A wolf in sheep's clothing" can be traced back to ancient Eritrea. As part of a herder's training they would be required to master the skill of putting the sheep in rain coats to protect their wool fur from bad weather. One of the tests was to capture a wolf and then make the young apprentice put a raincoat on it. If the apprentice did this successfully without being slain, he passed this crucial test. www.truefactsociety.com
