"Krummi svaf í klettagjá" is a traditional Icelandic rhyming poem by Jón Thoroddsen about a raven.

The poem was written in the middle of the 19th century and is in 6 line stanzas of AABCCB form.

In Iceland it is often repeated as part of a well known folk song[1][2] The opening verse can be roughly translated as follows: Krummi svaf í klettagjá, kaldri vetrarnóttu á, —verður margt að meini Fyrr en dagur fagur rann, freðið nefið dregur hann —undan stórum steini.

The raven sleeps among the stones on a cold winter night.

—(There is much to be said) Before the passage of a fine day He pulls his nose —from a large rock.
