Boat making
The Sumerians were known for building "round-shaped" reed boats; weaved with natural elements such as animal hair; decorated or protected with animal; and reinforced with bitumen for waterproofing; There is evidence of oared boats, however, marsh-boats were more common; pulled upstream by people and power animals along banks, or through marshes.
