Biblical scholars, archaeologists and others have tried to determine the exact location of Ophir. Vasco da Gama's companion Tomé Lopes reasoned that Ophir would have been the ancient name for Great Zimbabwe in Zimbabwe, the main center of southern African trade in gold in the Renaissance period — though the ruins at Great Zimbabwe are now dated to the medieval era, long after Solomon is said to have lived. The identification of Ophir with Sofala in Mozambique was mentioned by Milton in "Paradise Lost" (11:399-401), among many other works of literature and science.
