I want to know the answer to the following question:
Who mentions a Daurentius (577–579) that slew an Avar envoy of Khagan Bayan I?
All the background I'm provided with is that "The Avars asked the Slavs to accept the suzerainty of the Avars, he however declined and is reported as saying: "Others do not conquer our land, we conquer theirs –". Is that enough to answer the question?
Answer: no
