Riddles

A riddle is usualy a short composition which entails a doubled meaning or mystery in its words. Riddles have formed part on literature for centuries. In English literature, the first riddles were written in Old English in the Anglo-Saxon period. They were anonymous and they were composed to entertain the reader and to spread popular wisdom. These riddles refered to objects or processes related to war or religion, or they described household items or aspects of the natural world such as plants or natural phenomema. These compositions started to appear around 800D.c. in an oral form. Later, they were written in a book called Exeter Book between 915 and 1025. Thanks to this book about 90 of these traditional riddles have survived.

Now, I propose an easy Anglo-Saxon riddle to be solved. Do you dare to reveal the mystery?

"At night they come without being fetched,
And by day they are lost without being stolen."
