While the setting of Ars Magica is not historical Europe, Mythic Europe is heavily influenced by our real world's history and myths. Fortunately, there is no shortage of sources of information on these matters. Educating yourself and playing with history and folklore is part of the pleasure of playing Ars Magica.
