In some cultures, the peacock is honoured as the bringer of good fortune, and sometimes associated with royalty and glory. The "eye" is reputed to ward off evil spirits. The iridescent feathers are often used in jewellery and ornaments, and are associated with purity and pride.
My mum's opinions about peacock feathers were completely the opposite. She would never allow a peacock feather in the house. It was OK to have a peacock feather in the garden but woe betide anyone who dared to bring a peacock feather home. It was the "evil eye" on the feather, the bringer of bad luck. And not only simple bad luck.... misfortune, illness and even death. So, no peacock feathers ever crossed our doorstep. And I know it's only a superstition, but there are no peacock feathers in my house either! Just staying on the safe side.
And I had no idea that peacocks had such cute fluffy bottoms.
