What does poured oil on troubled waters mean?

Poured oil on troubled waters is an idiom that means to make a situation better or more peaceful. It is often used to describe a person or thing that brings calm to a chaotic or tense situation.

The phrase is based on the ancient practice of pouring oil on water to calm the waves. This was a common practice among sailors and fishermen, and it is believed to have originated in the Mediterranean Sea. The oil would form a thin layer on the surface of the water, which would help to reduce the friction between the water molecules and the air. This would result in a smoother, more peaceful sea.

The idiom "poured oil on troubled waters" was first recorded in the English language in the 16th century. It has been used by many famous writers and poets, including William Shakespeare and John Milton. The phrase is still commonly used today, and it is a powerful reminder that even in the most difficult of times, there is always hope for peace.
