This Aesop Fable was originally called the The Cock and the Pearl.
A rooster was strutting up and down the farmyard among the hens when suddenly he noticed something shining amongst the straw. “Ho! ho!” he said, “that’s for me,” and soon pulled it out from beneath the straw. It turned out to be a Pearl that by some chance had been lost in the yard. “You may be a treasure,” said the rooster, “to people that prize you, but for me – I would rather have a single barley-corn than a single pearl.”
Precious things are for those that can prize them.
