Leucothea was worshipped as a protector of sailors and those in distress at sea, often appearing to guide lost seafarers to safety. She was also associated with fertility, childbirth, and child-rearing. Palaemon, on the other hand, was venerated as a protector of harbors, fishermen, and seafarers in general. He was believed to have the power to calm storms and ensure safe passage for those navigating the seas.
