Some of you might be interested in this, an article from Scientific
American magazine in which the case is made for Egill Skallagrímsson
having been a sufferer of Paget's Disease. It's illustrated with
quotes from Egils saga and Egil's own poetry, and includes some
discussion of the wordplay there.
