I want to know the answer to the following question:
What type of instrument are the Sumerians thought to have invented to use at royal funerals?
All the background I'm provided with is that "It was believed that when people died, they would be confined to a gloomy world of Ereshkigal, whose realm was guarded by gateways with various monsters designed to prevent people entering or leaving.". Is that enough to answer the question?
Answer: no
