Asterix and the Normans

The Normans are depicted with such humor and charm—I'm curious whether this was based on historical stereotypes or a deliberate comic choice.

Their over-the-top attempts at intimidation made me laugh, but I wonder if it also subtly comments on how cultures view strength and bravado.

The mix of history and humor creates a unique atmosphere. I'm interested in whether the author had specific historical sources or just a love for that period.
