Definition: The word "Bosporus" appears in ancient Greek mythology to be a symbol of the world's great ocean, the Mediterranean Sea. In its earliest meaning, it was believed to contain an abundance of fresh water for life. Over time, its usage broadened to refer to all bodies of water in general or the whole earth. The word "Bosporus" is derived from the Greek word "bosporon," which means "mouth of a river." In the ancient world, this term often referred to a mouth like an oyster or worm. This interpretation was used in its more refined modern meaningβalso known as "port," port city, or "port town." In biblical imagery and mythology, "Bosporus" can also symbolize the waters of the earth's surface, which are frequently depicted as reflecting God's presence, warmth, and life force. It is often associated with the Mediterranean Sea, which is the most important source of fresh water on Earth. The term has a wide range of meanings and uses across different cultures, illustrating its versatility in ancient Greek and biblical contexts.
