The "Leiden Riddle" is an Old English riddle (which also survives in a similar form in the Exeter Book known as Exeter Book Riddle 33 or 35). It is noteworthy for being one of the earliest attested pieces of English poetry; one of only a small number of representatives of the Northumbrian dialect of Old English; one of only a relatively small number of Old English poems to survive in multiple manuscripts; and evidence for the translation of the Latin poetry of Aldhelm into Old English.
