I want to know the answer to the following question:
Who was the most famous prose writer in early Estonian history?
All the background I'm provided with is that "Among the most popular writers of the late 20th and early 21st centuries are Tõnu Õnnepalu and Andrus Kivirähk, who uses elements of Estonian folklore and mythology, deforming them into absurd and grotesque.". Is that enough to answer the question?
