Here is a special quote from the site above for Maria:
Till Ulenspiegel
[Ger.,=owl-mirror, hence English Owlglass], a north German or Dutch peasant clown of the 14th century who was immortalized in chapbooks describing his practical jokes on clerics and townsfolk -- his name reveals him as "the man who holds up mirrors for owls to look into". The first Till chapbook (c.1510) was probably in Saxon in a book by H. Bote, but the story it told spread all over Europe and North Britain. He allegedly was born in Kneitlingen (Braunschweig/ Lower Saxony) and died in 1350 in Moelln (Schleswig-Holstein). Till is the hero of a tone poem by Richard Strauss and of many novels, poems, and stories. Tyll Ulenspiegel is one of the variant spellings.
