Portunus, Portumnes, and Portunes are all variant spellings of the name of the Roman god of gates, doors, harbors, fords and possibly warehouses. Linguistically, the words opportunity and importune both derive from Portunes, who had influence over the timing of waves and thus could dictate the moments and events in the lives of those on or near the sea.
