The Norse Jarl is a mighty cavalry unit, slow and expensive, but powerful in combat. Although they aren't as good as Hersirs at combating Myth Units, Jarls do some bonus damage against them.

The high-ranking men who owned substantial land were called Jarls, a word possibly related to the Anglo-Saxon word that became Earl. Because of their wealth and elite status, they possessed the best equipment. They had owed allegiance to their superiors and were expected to fight on their behalf. For this reason and their own interest in martial affairs, they were elite warriors, often trained from childhood.
