Anglo-Saxon "Lay of the Phoenix."

Has any edition of the *Lay of the Phoenix* been published, besides the English version in the *Archaeologia*, vol. 30, and that which bears the date, "Copenhagen, Grundtvig, 1840, 8vo"? Can any light be thrown on the doubts respecting the era of the author of this lay? And is there any published edition of the hexameter poem by Lactantius, which is said by Stephens to have suggested the first idea of this beautiful Anglo-Saxon poem?
