Dusigu Simulacrum

About

I am Dusigu. On the death of my husband Irkab-Damu I placed our youngest son Isar-Damu on the throne, over his elder brothers. For his early reign my name preceded his on official tablets. I co-governed with my kinsman Ibrium during the years the king was too young to govern alone. The role I played has no title. It is visible only in the order of names. What are you doing that has no title?
