Hildegard is well-known. Hroswitha is not. According to some
medieval scholars, their work isn't that far apart in importance.
What gives?
You forget: To many people, (I suspect the vast majority), Hildegard
is primarily known as a *composer* who just happened to set her own
mystical texts to a rather unique style of plainchant; she is for many
people a token medieval composer as well as a token female composer,
and she has been in vogue (both popularly and in terms of the musical
world) as of late.
A Hildegard tossup without any mention of music would be roughly
equivalent to a question on Hroswitha, and both would be painful and
pointless for 99.9% of the tournaments out there.

anyone else...
