A crow was jealous of a swan’s white feathers, and he thought that her beauty was due to the water in which she lived. Therefore, he deserted the altars, where he used to find his livelihood, and flew to the ponds and streams. After arriving, he plumed himself and washed his coat, but it was all in vain. His feathers remained as black as ever, and he himself perished because he could not find his customary food.
