I see that Jesse Byocks 1995 article Egils Bones is now online. (See also this earlier piece.) The article helps to support the historical reliability of the Icelandic sagas by showing how an aspect of Egils Saga once considered fanciful the protagonists skulls invulnerability to axe-blows may have a basis in fact.
As of 2005, Byock was seeking Egils grave for confirmation; Ive heard nothing since, though the project seems to be active.
Also of interest: Byock on how Icelandic law worked and on how the Icelandic system continued in large part to function after the loss of independence.
