What body of water was known as the Pontus Euxinus and is located north and east of the Mediterranean Sea?

The body of water known as the Pontus Euxinus is the Black Sea. In ancient times, this body of water was referred to by that name, which translates to "Hospitable Sea," perhaps as a contrast to its earlier designation as the "Inhospitable Sea." The Black Sea is situated to the north and east of the Mediterranean Sea, bordered by several countries including Turkey, Ukraine, and Russia. Its importance in ancient trade, navigation, and agriculture highlighted its role in connecting various civilizations, which is why it was well-known to ancient peoples, including the Greeks and Romans. The other bodies of water listed do not share the same geographical position nor historical significance in relation to the Mediterranean Sea as the Black Sea does.
