This week we interview Dr. Matthew Harpster about his research using polygons to measure the density of maritime activity in the ancient Mediterranean Sea. He was a guest on the show back in 2020, and 4 years later he returns to discuss his new book that reveals patterns in ancient maritime activity and creates a narrative for this activity based on archaeological data from the sea floor.
