u, f., or rún-hending, f., is the name of the metre with end-rhymes, consecutive, not alternate; the word is now obsolete, and in ancient writers it only occurs in two places, the Ht. R. verse 24 and in Edda (Ht.), where the Cod. Reg. gives rún-, Edda i. 696 sqq. (the foot-notes); but one is tempted to suspect that this is corrupt, and that the true form was rim-, as im and un can hardly be distinguishedin MSS.; rím- would yield good sense, whereas rúm- is meaningless. The metre itself is evidently of foreign origin, borrowed from the A. S.: the first poem in this metre was the Höfuðl. of Egil, who had lived in England; it was little used throughout the 10th and the following centuries, and the few poems and fragments composed in it can be traced to Egil’s poem as their prototype. The single verse in Eg. ch. 27 is prob. a later composition.
